Complete Guide To String of Nickels (Dischidia) Care and Growth

Ideal Light for String of Nickels: The Dappled Canopy

In its natural habitat across Southeast Asia, the String of Nickels grows as an epiphyte. This means it lives on the branches of trees, tucked away under the canopy of larger forest giants. Because it lives under the shade of larger trees, it has adapted to thrive in dappled, filtered sunlight rather than the harsh, direct rays of the open sun.

For your home, this translates to bright, indirect light. A window facing North or East is usually perfect. If you have an East window, the plant will enjoy the gentle morning sun, which is rarely strong enough to burn the leaves. If you have a South or West window, make sure to set the plant back a few feet or use a sheer curtain to soften the rays. The goal is to mimic that forest canopy where the light is bright but the sun never hits the leaves directly for long periods.

I have found that the String of Nickels is slightly more sensitive to light than many Hoyas, like the Hoya Callistophylla. If the light is too harsh, the leaves will bleach and lose their lovely sage-green color. On the other hand, if the light is too low, the plant will effectively stop growing. It needs that bright environment to fuel its slow metabolism. Finding the 'sweet spot' is the key to seeing those lush, overlapping coins.

Signs of Light Stress in Dischidia Nummularia

Watching your plant's leaves is the best way to tell if the lighting is correct.

• Too Much Sun: If the leaves start turning a pale yellow or develop a reddish tint (sun-stressing), it is getting too much direct light. While some growers like the stressed look, too much will eventually lead to crispy, brown patches and stunted growth. The leaves might also feel thinner and more like paper than succulent coins.
• Too Little Light: If the spacing between the leaves (the internodes) starts to get very long and the new leaves look tiny and weak, it is searching for more light. This is called etiolation. In low light, the plant loses its characteristic 'dense' look and starts to appear stringy and sparse. Move it closer to a light source to keep that tight, coin-like growth pattern that makes the plant so attractive.

If you are using artificial lights, like LED grow lights, aim for a placement about 12 to 18 inches away from the plant. This provides plenty of photons without the risk of heat damage.

The Soak and Dry Method for String of Nickels

Because the leaves of the String of Nickels are succulent, they are designed to store water for dry periods. This means the plant is much more tolerant of underwatering than overwatering. In the wild, they experience periods of heavy monsoon rain followed by drying winds on the tree branches. This cycle is what we want to replicate in the home environment.

The best way to water is the 'soak and dry' method. Wait until the potting media is completely dry before giving it a thorough drink. Unlike many tropical plants that want consistent moisture, the String of Nickels needs its roots to dry out and breathe. If the roots stay wet for too long, the lack of oxygen will cause them to rot almost instantly. I often tell people that it is better to forget to water for a week than to water it a day too early.

When you do water, make sure to saturate the media until water runs out of the drainage holes. If your plant is in a very dense moss mix, you might find that bottom watering is more effective. Fill a bowl with an inch or two of water and let the pot sit in it for 15 to 20 minutes. This allows the moss to wick up moisture through capillary action without disturbing the delicate aerial roots on the surface.

Using the Touch Test for Moisture

Forget about a strict calendar schedule like 'water every Monday.' The temperature and humidity in your home change with the seasons, and so does the plant's water usage. The best way to know if your Dischidia needs water is the squeeze test. Gently pick a leaf near the base of the plant and give it a very light squeeze between your thumb and forefinger.

• Firm Leaves: The plant has plenty of water stored in its tissue. Do not water yet.
• Soft or Wrinkled Leaves: The plant has used up its reserves and the leaves are losing their turgor pressure. This is the signal that it is ready for a drink.

This method is foolproof because it accounts for the actual state of the plant. During a hot summer, you might find yourself watering every week, while in a cool winter, the plant might go three weeks without needing a drop. Always trust the plant over the calendar. It's the most reliable way to avoid the dreaded root rot.

The Role of Water Quality

While the String of Nickels is not as fussy as a Calathea, it does appreciate clean water. If your tap water is very hard or contains high levels of chlorine and fluoride, you might notice white mineral deposits forming on the leaves or the tips of the roots. This can eventually lead to 'salt burn' on the sensitive growing tips.

If possible, use rainwater or distilled water. If you must use tap water, let it sit out for 24 hours to allow some of the chemicals to dissipate. This simple step can keep your foliage looking vibrant and prevent the build-up of salts in the potting media.

Why Standard Soil Fails the String of Nickels

If you plant your String of Nickels in standard bagged potting soil, you are likely setting it up for a short life. In the wild, these plants are not 'grounded' in the traditional sense. They live on trees with their roots exposed to the air. Their roots have evolved to grab onto bark and moss, not to sit in dense, heavy, peat-based dirt that stays wet for days.

Standard soil holds far too much moisture and lacks the structural gaps needed for air to reach the roots. For an epiphyte like the String of Nickels, this lack of oxygen at the root level leads to rapid rot. I have seen many people lose their plants because they thought 'potting soil' was a universal requirement. For a Dischidia, it is a death sentence. You need a mix that is incredibly chunky and provides maximum airflow to the root zone.

The Perfect Dischidia Potting Recipe

To keep your plant happy, you want to create a mix that mimics a tree branch. I recommend a blend of:

• Orchid Bark (Large or Medium): This provides the large surfaces for roots to cling to and creates massive air pockets in the pot. It is the 'bones' of the mix.
• Coco Chips or Husk: These hold onto a tiny bit of moisture without becoming soggy or breaking down quickly.
• Perlite or Pumice: These inorganic materials ensure the mix never compacts over time, keeping those air gaps open even after years of watering.
• Long-Fiber Sphagnum Moss: Adding just a handful of moss to the mix helps maintain a bit of humidity around the roots without making the entire pot a swamp.

Think of it more like an orchid mix or a Hoya Potting Mix than a succulent mix. For a deeper understanding of why drainage is so important, take a look at our Complete Soil Guide. The goal is to create a substrate that you can pour water through and have it run out the bottom almost instantly. If you can't make your own, look for a high-quality 'epiphyte mix' or a chunky orchid bark blend.

More Than Just a Pretty Face: A Partnership in the Wild

One of the most incredible things about the Dischidia genus, including our String of Nickels, is its relationship with ants. In its native tropical forests, the String of Nickels is what we call a myrmecophyte, or an "ant plant." This isn't just a random occurrence; it is a complex, mutually beneficial partnership that has evolved over millions of years.

The plant provides a home for certain species of ants. In some Dischidia varieties, the leaves are hollowed out like balloons (like the Dischidia pectinoides) specifically to house ant colonies. While the String of Nickels doesn't have those large balloon leaves, it still participates in this relationship. The ants find shelter among the dense, overlapping coin-shaped leaves and within the crevices of the tree bark where the plant is rooted.

In return for this free housing, the ants act as a private security force. They protect the plant from larger herbivores, like caterpillars or grasshoppers, that might want to eat the succulent leaves. The ants also provide a surprising source of fertilizer. Their waste products and the debris they bring into their nests are rich in nitrogen, which the plant's aerial roots absorb. It is a perfect closed-loop system of protection and nutrition.

What This Means for You as an Indoor Grower

While you probably don't want a colony of ants living in your living room, understanding this relationship tells you a lot about the plant's needs.

• Aerial Roots are Important: Those little white 'hairs' you see on the stems are actively hunting for nutrients. When you mist or fertilize, remember that the plant is designed to 'eat' through these roots as much as its main root system.
• Vulnerability to Pests: Because the plant doesn't have its ant defenders in your home, it is much more vulnerable to things like mealybugs. You have to step in and be the 'security force' that the ants would normally be.
• Airflow is Everything: In nature, the nests are well-ventilated by the movement of the ants and the wind in the trees. This is why stagnant air is so deadly for a Dischidia indoors. It simply isn't built to live in a still, humid box.

I find that knowing the biological history of a plant makes the care much more intuitive. You aren't just watering a pot; you are managing a tiny piece of evolution that is used to a very active, complex environment.

Why Mounting is the Best Way to Grow String of Nickels

As we discussed in the soil section, the String of Nickels is a true epiphyte. While it can live in a pot for a long time, it never looks more 'at home' than when it is mounted on a piece of bark. Mounting allows the plant to grow in all 360 degrees, just like it would on a tree limb in Southeast Asia.

Moreover, mounting virtually eliminates the risk of root rot. Because the roots are exposed to the air and any excess water drips right off the bottom of the mount, the roots never sit in a stagnant pool of moisture. If you have a history of overwatering your plants, a mount is a fantastic way to 'idiot-proof' your Dischidia care.

Materials You Will Need for Your First Mount

Before you start, gather these supplies:

• A Support: Cork bark is the gold standard because it is porous and lasts forever without rotting. You can also use cedar wood or even a rough piece of driftwood. Avoid treated woods from hardware stores as the chemicals can be toxic to the plant.
• Media: High-quality long-fiber sphagnum moss. This will act as the 'root ball' for the plant.
• Binding: Clear fishing line or green floral wire. Fishing line is nearly invisible, which looks great once the plant matures, but wire is easier to handle for beginners.
• The Plant: A healthy String of Nickels with at least 5 or 6 well-developed strands.

Step-by-Step: The Mounting Process

1. Soak Your Moss: Place your sphagnum moss in a bowl of warm water for about 10 minutes until it is fully hydrated. Squeeze it out thoroughly so it is damp but not dripping.
2. Prepare the Base: Lay your piece of cork bark flat. If you want to hang it, drill a small hole in the top and attach a wire loop now, before the plant is on it.
3. Create a Moss Bed: Take a handful of the damp moss and flatten it out on the bark where you want the plant to live. This creates a soft, humid cushion for the roots.
4. Position the Plant: Gently remove your Dischidia from its pot and shake off any loose soil. Place the root system directly onto the moss bed. You can even lay some of the stems onto the moss to encourage more attachment points.
5. Secure with Line: Wrap your fishing line or wire around the bark and the base of the plant. You want it to be firm enough that the plant doesn't wobble, but not so tight that you cut into the succulent stems. I usually make about 10 to 15 wraps in different directions to ensure it is very secure.
6. The First Soak: Once the plant is secured, give the entire mount a good spray with water to settle everything into place. Hang it in a spot with bright, indirect light and enjoy your new living wall art!

Feeding a Light Eater

The String of Nickels is a slow-growing plant that does not require much heavy feeding. Because it lives on trees, it is used to getting its nutrients from decaying organic matter like fallen leaves or bird droppings that wash down the bark during rainstorms. It is a very efficient scavenger of nutrients.

I find that fertilizing about three or four times a year during the active growing season (Spring and Summer) is plenty. If you over-fertilize, you risk burning the sensitive roots or causing weak, leggy growth that ruins the plant's tight, coin-like shape. In the winter months, when growth naturally slows down, you should stop fertilizing entirely.

Best Fertilizer Types for Dischidia

Since this plant can actually absorb some nutrients through its leaves and its numerous aerial roots, a liquid fertilizer is far better than slow-release pellets.

• Orchid Mist: A diluted, spray-on orchid fertilizer is excellent for Dischidias. You can simply mist the leaves once a month during summer. This mimics the way they get 'washed' with nutrients in the forest.
• Diluted Liquid Feed: If you prefer a traditional approach, use a standard balanced houseplant fertilizer (like a 10-10-10), but dilute it to about one-quarter of the recommended strength.

Always make sure the potting media is slightly damp before applying a liquid fertilizer. Applying fertilizer to bone-dry roots can cause 'fertilizer burn,' where the salts in the fertilizer pull moisture out of the root tissue, causing it to die.

Warmth is Key for Tropical Success

Coming from tropical regions in Southeast Asia, the String of Nickels loves warmth. It is most comfortable in temperatures between 60°F and 80°F (15°C to 27°C). If you are comfortable in a room wearing a light shirt, your plant probably is too.

It can tolerate higher temperatures, even into the 90s, as long as the humidity is also very high and there is good airflow. However, it will suffer if the air becomes too stagnant and hot, which can lead to fungal issues or leaf drop.

Protecting From Cold Drafts and Winter Shocks

The number one climate killer for this plant is a cold draft. Because it is a tropical epiphyte, it has zero frost tolerance. Do not place it directly in the path of an air conditioning vent or near a drafty window in the winter.

Even a few hours of exposure to temperatures below 50°F can cause the plant to go into shock. You might notice the leaves turning a dark, translucent color before they eventually turn black and fall off. If you live in a cold climate, make sure your hanging baskets are pulled away from the window glass during the coldest nights of the year.

Mimicking the Rainforest Air in Your Home

In the wild, these plants are constantly bathed in high humidity. While the String of Nickels is surprisingly tough and can survive in average home humidity (around 30 to 40%), it will not truly thrive there.

Ideally, you should aim for a humidity level of 50% to 70%. In high humidity, the plant feels 'safe' enough to grow its leaves much closer together, creating that dense, coin-like appearance that everyone wants. In dry air, the leaves tend to stay smaller and flatter, and the plant grows even slower than usual as it tries to conserve moisture.

Easy Ways to Boost Humidity Without a Greenhouse

You don't need a professional greenhouse to keep a Dischidia happy. There are several simple tricks:

• Grouping Your Plants: Place it near other plants. As they transpire, they release moisture into the air, creating a little micro-climate of humidity.
• Pebble Trays: Set the pot on a tray filled with pebbles and water. As the water evaporates, it rises directly around the plant. Just make sure the bottom of the pot isn't sitting in the water, as this will lead to root rot.
• Humidifiers: If your home is very dry (especially during the winter when the heater is running), a small ultrasonic humidifier nearby is the most effective solution for consistent growth.
• Bathrooms: If your bathroom has a window with bright light, the steam from your daily shower will make the String of Nickels feel right at home. For more tips on maintaining the right environment, read our guide on Boosting Indoor Humidity.

What do the Flowers Look Like?

While we mostly grow the String of Nickels for its stunning foliage, it does produce flowers. They are tiny, urn-shaped, and usually a creamy white or pale yellow. They are so microscopic that you might miss them if you aren't looking closely! They often appear at the leaf nodes, tucked between the round leaves, during the Spring months.

I remember the first time I noticed them; I thought my plant had some white bumps until I looked through a magnifying glass and saw the perfect little bells. They don't have a strong scent, but they add a wonderful bit of detail to a healthy plant.

How to Encourage Your Dischidia to Bloom

If you want to see those tiny flowers, you need to provide the plant with its ideal conditions consistently. Bright, indirect light is the most important factor. Without enough light energy, the plant simply won't have the resources to prioritize leaf growth over blooming.

A slight reduction in watering during the late winter, combined with the naturally increasing day length in the Spring, can often trigger the plant to bloom. It is its way of saying 'thank you' for the good care. Once the flowers fade, you can just leave them; they will eventually dry up and fall off on their own.

Dischidia Nummularia vs Dischidia Ovata: The Round and the Oval

The most common lookalike is its cousin, Dischidia Ovata, also known as the Watermelon Dischidia. While they share the same trailing growth habit and epiphytic nature, the leaves are the giveaway. Ovata has oval-shaped leaves with distinctive white or silver stripes that look like watermelon rinds.

Dischidia Nummularia is prized for its perfectly round, solid pale green or silvery-green leaves. If you see stripes, you are looking at an Ovata. Both are wonderful, but the Nummularia has a much more 'graphic' and clean look that fits perfectly into modern, minimalist decor. I often suggest people get both and hang them together; the contrast between the stripes and the solid green coins is visually fantastic and really highlights the diversity of the genus. You can find similar round-leafed beauty in the String of Turtles, though its care is slightly different.

Other Fascinating Dischidia Species for Collectors

If you enjoy the String of Nickels, the world of Dischidias has plenty more to offer. These plants all share the same basic care requirements but look drastically different:

• Dischidia Ruscifolia (Million Hearts): This one features tiny, heart-shaped leaves that grow in dense pairs along the stem. It is incredibly prolific and creates a thick curtain of green hearts. It is a bit faster-growing than the String of Nickels.
• Dischidia Pectinoides (Ant Plant): A truly bizarre variety that grows hollow, balloon-like leaves. In the wild, these leaves provide a home for ants, which in turn protect the plant and provide it with nutrients. It is a fantastic conversation piece and a favorite for terrarium lovers.
• Dischidia Vidallii: Similar to the Ant Plant but with even more complex 'bladder' leaves that look like little puffed-up sacks.

I recommend starting with the String of Nickels as it is one of the most resilient members of the family. Once you master its watering and understand its need for airflow, moving into the more exotic species becomes much easier.

When is it Actually Time to Repot a Dischidia?

The String of Nickels is not like a Monstera that will bust out of its pot in a year. It has a very small, shallow root system because it is designed to live in the crevices of tree bark where space is limited. It actually prefers to be 'root bound' or 'pot bound.' In fact, putting it in a pot that is too large is one of the quickest ways to kill it, as the extra soil will stay wet for far too long, starving the roots of oxygen.

You should only consider repotting every three or four years. The main reason to repot isn't usually because the plant has grown too large for its space, but because the potting media itself is starting to degrade. Over time, orchid bark and moss break down and lose their ability to hold air. When the mix starts looking like dark, soggy mush, it is time for a refresh.

Choosing the Right Container for an Epiphyte

Because the roots of the String of Nickels are so small and need so much oxygen, always use a pot that has excellent drainage.

• Terracotta Pots: This is my top recommendation for almost everyone. The porous clay allowed moisture to evaporate through the sides of the pot, which prevents the 'swamp effect' that kills Dischidias. It's a natural air-conditioner for the roots.
• Plastic Nursery Pots: These are fine as long as they have plenty of holes. If yours doesn't have enough, you can even use a soldering iron or a drill to add extra holes to the sides of the pot for better airflow.
• Shallow Pots or 'Bulb Pans': Avoid deep, traditional pots. A shallow 'bulb pan' or a small hanging basket is ideal. The roots of the String of Nickels will rarely go deeper than three or four inches, so any soil deeper than that is just a risk for rot. If you are new to this process, our Step-by-Step Repotting Guide will show you exactly how to handle delicate roots.

How to Encourage a Fuller, Lush Appearance

As a trailing plant, the String of Nickels can sometimes become thin or 'bald' at the top of the pot while the strands get very long. This is usually because the plant is putting all its energy into the growing tips at the ends of the vines. This is called apical dominance.

To fix this and encourage a fuller look, you can prune the ends of the vines. When you cut a vine, it triggers the plant to branch out from the nodes further up the stem. Often, it will produce two or three new vines where there was once only one. This is the 'secret' to those incredibly thick, lush hanging baskets you see in professional plant shops.

Routine Maintenance and Tool Hygiene

Always use sharp, clean scissors or snips. I recommend wiping your tools with rubbing alcohol before and after pruning to prevent the spread of any potential bacteria or fungus.

You can remove any dead, yellowing, or shriveled leaves at any time. If a strand gets damaged or looks unhealthy, don't be afraid to cut it back to a healthy node. These plants are quite resilient to pruning, and the sections you remove can actually be used for propagation. It is a win-win situation for you and the health of the plant.

Winter Care: The Rest Period

As the days get shorter and the temperature drops, your String of Nickels will naturally enter a semi-dormant state. Its metabolism slows down, and it will stop producing new leaves. This is a very sensitive time for the plant.

The most important winter rule is to reduce watering significantly. Because the plant isn't growing, its roots aren't pulling up much moisture. If you continue to water like you did in July, the soil will stay wet for far too long, leading to winter root rot. I recommend waiting for the leaves to look slightly thinner than usual before even considering watering during December and January. Check out our blog post on How to Water Houseplants in Winter for more specific seasonal advice.

You also need to watch out for dry air from heaters. While the plant likes to be dry at the roots, it still needs humidity in the air. Placing it near a radiator is a double-whammy: the heat will bake the soil while the dry air shrivels the leaves. Keep it in a bright spot, but far away from any direct heat sources. We have more tips on this in our guide to Preparing Houseplants for Winter.

Spring and Summer: The Growing Season

When the first signs of Spring arrive, you will see the plant 'wake up.' The growing tips will start to turn a brighter green and tiny new leaves will appear. This is the time to slowly increase your watering frequency and start your fertilization routine.

The String of Nickels loves the extra light of summer, but be careful of the magnifying effect of window glass. Afternoon sun in July can be much more intense than in March. If the leaves start looking a bit yellow or 'bleached,' it might be a sign to move it a few feet back from the window or add a sheer curtain. This is also the best time for propagation, as the warm temperatures and bright light give cuttings the best chance of rooting quickly.

The Moss and Box Method: High Success Propagation

The most successful way to propagate String of Nickels is the propagation box method. Because these plants have tiny roots, they often dry out before they can establish in a traditional soil-potting setup.

1. Take Cuttings: Use clean snips to take a strand of the plant that is about 4 to 6 inches long. Ensure the cutting has at least 4 nodes.
2. Prepare the Bed: Get some high-quality long-fiber sphagnum moss. Soak it in water and then squeeze it out until it is damp like a wrung-out sponge, but not dripping wet.
3. Lay it Down: Instead of sticking the stem into the moss (which can sometimes lead to rot), lay the entire strand FLAT on top of the moss. This is the most important part of the process!
4. Contact is Key: Make sure the nodes (the joints where the leaves meet the stem) are in direct contact with the moss. This is where the new roots will emerge. You can even use a small piece of bent wire or a 'Bobby pin' to gently pin the stem onto the moss so it doesn't move.
5. Seal for Humidity: Place the moss and cuttings into a clear plastic container with a lid. This traps the humidity, creating a tiny, humid greenhouse.
6. Patience and Airflow: Place the box in a bright spot with no direct sun. Open the lid once every few days to let in some fresh air and prevent mold. Within three to four weeks, you should see white roots diving into the moss. Once the roots are about an inch long, you can move the cuttings into a small pot with the epiphyte mix we discussed earlier.

The Butterfly Method for Faster Bushiness

If you want to create a very full pot quickly, the Butterfly Method is your best friend. Instead of long strands, you use single-node cuttings.

1. Prepare Cuttings: Cut a long vine into sections where each section has two leaves and a small piece of stem (it looks like a butterfly!).
2. Planting: Lay these 'butterflies' flat on top of damp moss or a very airy soil mix.
3. Growth: Each node will eventually send out a new vine. By planting many 'butterflies' in one pot, you create a much denser plant than by just planting two or three long strands. It takes a bit more effort to set up, but the result is a professional-looking, lush basket in half the time.

Dealing with Mealybugs: The Common Enemy

The most common pests for Dischidia are mealybugs. These annoying insects love to hide in the tight, protected spaces between the round leaves and along the vines. They look like tiny bits of white cotton or fuzz. If you see sticky residue on your leaves (honeydew), that is another sign that you have uninvited guests.

If you see them, don't panic, but act quickly.

• Spot Treatment: For a small infestation, use a cotton swab dipped in 70% rubbing alcohol to dab the bugs away. The alcohol dissolves their waxy coat and kills them almost instantly.
• Total Coverage: For a larger problem, a spray of Neem oil or an insecticidal soap is effective. Because the leaves are so small and dense, make sure to spray from all angles - literally turn the plant upside down if you have to - to reach every hiding spot. Repeating the treatment every week for a month is usually necessary to catch any newly hatched bugs.

Scale Insects and Their Disguises

Another common issue is scale insects. Unlike mealybugs, scale doesn't look like an insect at all. They look like small, hard brown or tan bumps on the stems or the undersides of leaves. They are often mistaken for natural growth or woody parts of the plant.

To treat scale, you can also use the alcohol dab method, but you might need to gently scrape the bumps off with a fingernail or a soft toothbrush. For serious infestations, a systemic pesticide that the plant absorbs through its roots is often the only permanent solution.

The Hanging Waterfall Aesthetic

The most classic way to style a String of Nickels is in a hanging basket. As the vines grow, they will spill over the sides like a green waterfall. This works perfectly in macrame hangers or simple ceramic pots hung from a ceiling hook.

I love hanging mine in front of a window where the light can shine through the pale green leaves. It is a great way to add a layer of 'vertical green' to a room without taking up valuable shelf or floor space. Over time, the vines can reach several feet in length, creating a stunning natural curtain.

Vertical Living Walls and Terrariums

Because the String of Nickels is a true epiphyte, it is an absolute star in tropical terrariums and living walls. You can mount it directly to the background wall of a large terrarium using a bit of moss and some fishing line.

It will slowly grow and 'curtain' the wall, providing a lush, wild forest feel. They are particularly good for vivariums housing small reptiles or frogs, as the leaves provide excellent hiding spots. Just make sure the terrarium has good airflow, as stagnant, wet air is the enemy of this plant and can lead to mildew or rot issues in a closed environment.

Success Strategies for the Long Haul

If you want your String of Nickels to not only survive but truly thrive for years, keep these ten insider tips in mind:

1. Don't Overpot: A big pot holds too much water for too long. Keep the plant in a small, tight container that reflects its small root system.
2. Airflow is Vital: These plants breathe through their roots and their porous leaves. A stuffy, closed room is a recipe for fungal trouble. A small fan in the room can make a world of difference.
3. The Rainwater Advantage: If your tap water is very hard, the leaves might develop white mineral spots that are hard to clean. Using rainwater or distilled water keeps the leaves looking pristine and vibrant.
4. Morning Sun is a Cheat Code: A little bit of gentle morning sun (the first two hours of the day) is the secret to faster growth and more prolific leaf production.
5. Patience is Your Best Tool: This is not a fast-growing plant. Don't worry if you don't see new growth every week. Enjoy the slow, steady progress.
6. Mist with Caution: While they love humidity, constant wet leaves in a cool, dark room can lead to fungal issues. If you mist, do it only in the morning so the water has time to evaporate before nightfall.
7. Check for Ants: In nature, their hollow leaves can house ants in a symbiotic relationship. If you see ants on your plant indoors, check for hidden pests like aphids, as the ants might be protecting them for their sweet 'honeydew.'
8. Winter Rest Period: Reduce your watering significantly in the winter months when the light is lower and the plant's metabolism slows down.
9. Terracotta is a Lifesaver: If you tend to be a 'heavy-handed' waterer, a terracotta pot will help pull excess moisture away from the roots, potentially saving your plant's life.
10. Get to Know the Feel: Frequently touch your plant's leaves. Once you learn the 'feel' of a healthy, fully hydrated leaf, you will have the most accurate moisture meter in the world right at your fingertips!

Is the String of Nickels toxic to cats and dogs?

According to the ASPCA, most Dischidia species are considered non-toxic to domestic pets. However, like many members of the Apocynaceae family, they produce a milky white sap that can be irritating to the skin and eyes. If your pet decides to take a bite, it might cause mild stomach upset or drooling. I always recommend keeping your plants out of reach of curious pets and children, just to be safe.

How fast does Dischidia Nummularia grow indoors?

I'll be honest with you: it is very slow. Unlike a Pothos that can grow several inches in a week, the String of Nickels might only put out a few new nodes every month, especially during the winter. Don't be discouraged if it looks like nothing is happening for a while. It is a slow and steady grower.

Can I grow String of Nickels in a regular succulent soil mix?

I wouldn't recommend using a standard succulent soil right out of the bag. While it drains better than regular potting soil, it is often still too dense for the delicate aerial roots of a Dischidia. Most succulent mixes are designed for desert plants that live in the ground. The String of Nickels lives in the air! You are better off using a mix that is at least 50% orchid bark.

Why are the leaves on my String of Nickels turning yellow?

Yellow leaves on a Dischidia are almost always a sign of overwatering or poor drainage. If the roots stay wet for too long, they begin to die, and the plant can no longer pull up nutrients, which causes the leaves to yellow and drop. Check the bottom of the pot to make sure the drainage holes aren't blocked, and verify that your potting media hasn't broken down.

Does the String of Nickels need a lot of humidity?

It definitely prefers high humidity, ideally between 50% and 70%. In a very dry home, you might notice that the leaves stay small and the vines don't grow as quickly. While it can survive in lower humidity, it won't have that classic 'lush' look. Using a humidifier or placing the plant in a bright bathroom is an excellent way to keep it happy.

Can I mount my String of Nickels on a wall?

Yes, and it looks beautiful! Mounting them on cork bark or cedar is one of the best ways to display a Dischidia because it mimics its natural environment. Just remember that mounted plants dry out much faster than those in pots. You will need to be diligent about misting it or giving the whole mount a soak in water at least once or twice a week.

What are the tiny white bumps on the stems?

If they look like little cottony balls, they are likely mealybugs. If they are harder and look more like nodes, they might be aerial roots starting to form. Dischidias use these aerial roots to grab onto trees and to pull moisture from the air. If you see them, it's a sign your plant is healthy and looking for something to climb! However, always check closely with a magnifying glass to make sure they aren't pests.

How do I get my plant to look fuller at the top?

The best way to get a full 'bald-free' top is to prune the ends of the vines. This stops the plant from putting all its energy into the growing tips and forces it to branch out from the nodes at the base of the plant. You can also take small cuttings and plant them directly back into the top of the pot to fill in any sparse areas.

Can I grow this plant under grow lights?

Absolutely. The String of Nickels does very well under artificial lighting. Aim for a full-spectrum LED grow light and place the plant about 12 to 18 inches away. Keep the lights on for about 12 to 14 hours a day to mimic a tropical day-length.

Why are the leaves on my plant turning red?

A reddish tint on the leaves is usually a sign of 'sun stress.' This happens when the plant is getting a bit more light than it strictly needs. Many growers actually prefer this look as it can be quite attractive. However, if the leaves start to look bleached or develop brown, crispy spots, it means the sun stress has turned into a sun burn.

How often should I repot my String of Nickels?

Rarely. These plants have tiny root systems and hate being disturbed. I only recommend repotting once every three to four years, and only if the potting media has broken down. If the plant is growing well and the water is still draining through the pot quickly, there is no reason to move it.

What should I do if my plant drops its leaves?

Sudden leaf drop is usually a sign of a shock to the system. This could be a sudden cold draft, a dramatic change in lighting, or a severe case of overwatering. Check the stems first. If they are still firm and green, the plant will likely recover once you address the underlying stress. If the stems are black and mushy, you are dealing with rot.

Why are the leaves shriveling?

Dehydration. The leaves store water. If they pucker, it means the plant has used up its reserves. Water it!

Is it a succulent?

Technically an epiphyte succulent. It behaves like an orchid (needs air at roots) but stores water like a succulent.
