String of Coins Plant Care — Your Complete Guide

Sharing is caring!


The String of Coins is a great choice if you want a unique succulent. This unusual plant looks stunning as a spiller in a hanging basket.

It also pairs well with other succulents in an indoor cactus garden. 

The String of Coins is named after its leaves’ round shape, which resembles a coin. The leaves grow symmetrically on long trailing stems, named String of Coins.

The foliage has a very attractive blue-green to silver-green hue. Small clusters of yellow-green flowers may appear in spring.

I was thrilled to find this plant at my local nursery, and it has become a focal point on my enclosed patio. 

The official name is Xerosicyos danguyi, and the plant is native to the cliff-filled regions of south-eastern Madagascar. 

If you treat String of Coins as a succulent and give it the correct conditions, it will grow happily in your home with minimal fuss and bother. 

Here is a full guide on how to care for your String of Coins. 

String of Coins Care

The String of Coins grows in well-draining, slightly acidic, succulent, or cactus soil. It requires a warm position with ideal temperatures between 65°F to 80°F (18°C to 27°C) and at least 6 to 8 hours of bright light or partial sunlight per day. Low to average humidity is best. Water sparingly.

The String of Coins grows naturally in well-draining soil that easily dries out after watering. It is susceptible to damp soil, with the roots rotting if they remain wet. It grows well in soils with a 6.0-6.5 pH reading. A ready-made or homemade succulent or cactus mix is ideal. 

The String of Coins is a succulent, so it prefers very well-draining soil. It will not thrive well in damp soil as the roots rot and then eventually die.

I chose a ready-made cactus mix from my local nursery for my plant. A cactus mix contains a combination of clay, sand, and silt in a ratio of 20%, 40%, and 40%.

Using of all-purpose potting soil for the String of Coins isn’t recommended. It requires loose, very well-aerated soil that dries out between watering sessions. 

The String of Coins likes slightly acidic soil. Measure your soil with a home pH testing kit and check for a reading of 6.0 to 6.5.

The String of Coins enjoys light and sun with at least 6-8 hours of indirect or direct light daily. It will tolerate partial and full sunlight. South-facing rooms are ideal. North-facing rooms will be too dark and cold. This plant won’t grow in shady spots. 

String of Coins will be the perfect plant if you have a bright sunny room. It loves sunlight.

The String of Coins requires at least 6-8 hours of daily exposure to indirect or direct light. They can tolerate partial sunlight and are also happy in direct sunlight.

Their natural habitat is hot and dry, and sunny! So you need sun. 

Place your plant on a windowsill or near a window in a south-facing room, and it will flourish. 


The String of Coins is drought-tolerant and can survive with minimal water. Use the soak-and-dry watering method to thoroughly soak the soil and allow it to dry completely before watering again. Ensure that your soil does not remain damp. Water infrequently during the winter months. 

The high cliffs of Madagascar are home to String of Coins. In these areas, the soil is loose and sandy that doesn’t retain water.

The String of Coins belongs to the succulent family and can survive on very little water. 

Your soil must be very well-draining. When you water, use the soak-and-dry method – give your plant a good drenching and allow the water to run out of the pot via the drainage holes at the base.

If the water does not drain from your pot, the roots will rot, and your plant will die. 

Don’t water the String of Coins again until the soil’s completely dry. Water in spring and summer and keep it dry in winter. 


The String of Coins can survive in a range of temperatures from 20°F to over 90°F (-6°C to 32°C). The ideal temperature range is 65°F to 80°F (18°C to 27°C). Although it can tolerate some frost, it is best to protect it from exposure to frost. It will tolerate heat up to 104°F (40°C). 

The String of Coins enjoys dry and hot climates. Your plant will do fine in the USA in 9b-11b USDA hardiness zones.

It is tolerant of a wide range of temperatures and can survive in temperatures from 20°F to over 90°F (-6°C to 32°C). The ideal temperature range is 65°F to 80°F (18°C to 27°C).

Your average home is ideal for the String of Coins. 

Although it can tolerate some frost and lower temperatures, it is best to protect your plant from exposure to frost. Being a succulent, it will tolerate occasional heat up to 104°F (40°C). 


The String of Coins prefers low to moderate humidity as its natural habitat is dry and hot. Do not place your plant in warm damp rooms or near humidifiers. An average home with around 40% to 50% humidity is ideal. If your region is very humid, you could consider installing a dehumidifier.

The String of Coins does best in conditions of low to average humidity. This plant detests being in a room that’s damp or very humid.

An average home with 40% to 50% humidity will suit your plant. 

If you live in a humid region, you could consider installing a dehumidifier to dry the air. Open windows when possible so your String of Coins plant receives adequate airflow.

Many indoor gardeners run humidifiers to increase the air moisture for tropical plants. Ensure that your String of Coins does not live in this environment – it will not be happy. 


The String of Coins is a hardy plant and does not require fertilizing; if you want to fertilize, do it once in the summer months. Use a balanced and water-soluble fertilizer diluted to half the strength. Do not fertilize in winter. 

These plants do not require fertilizer. If you enjoy fertilizing your plants, you can boost them once during summer.

Do not fertilize in winter. Use a balanced and water-soluble fertilizer diluted to half-strength.

Water-soluble fertilizers give your plants an instant boost of nutrients. Pour the fertilizer onto the soil, taking care not to splash the plant.

Fertilizers poured directly onto the plant will damage leaves, stems, and flowers. 

I always look for a natural organic mix when buying ready-made fertilizer. I prefer to stay away from chemical mixes whenever I can. 


The String of Coins grows to a height of 8 inches (20cm) and a spread of 8 inches (20cm). It offers long tendrils that can reach lengths of 17 inches (45cm). The leaves are a round coin shape and have a silvery-green to blue-green color. Small yellow-green flowers may be produced in spring.

The String of Coins is ideal for planting as a pot spiller or in a hanging basket

If your plant is growing outdoors, it will grow as a scrambling vine and get much bigger, reaching a size of 12 to 16 feet (3.6m to 4.8m) high and 4 to 6 feet (1.2m to 1.8m) wide. 

The plant is named for the shape of the leaves, which resemble round coins on a long string. The leaves are a lovely silvery-green to blue-green color and can grow to a size of 1 to 2 inches (2.5cm to 5cm).

Being a succulent, the leaves don’t drop in winter, making this an attractive plant to maintain interest in your indoor garden or on a patio.

In spring, you may get a show of small insignificant yellow-green flowers followed by tiny fruits. 

The plant has a moderate growth rate at first but speeds up once established. You may have to repot the String of Coins once a year if the plant becomes rootbound. 


Plant your String of Coins into very well-draining, sandy soil. A cactus or succulent mix is best for your String of Coins. Ensure that your pot has drainage holes. Once it becomes rootbound, repot it in spring. Do not use all-purpose potting soil as it is too moist and rich.

The String of Coins does best in a hanging basket or a small pot where the stems can trail downwards. 

Choose a succulent or cactus mix. Place some gravel at the pot’s base to ensure that the water can flow freely from the pot.

Place your plant carefully into a hole in the middle of the pot. Close up the hole with sand.

Drench your plant and allow the water to drain out. Until you’re certain that the soil’s dry, don’t water the plant again. 

You can repot in the spring if you see that the plant has become rootbound or want to replenish your plant with fresh soil.

Use a pot that’s around 3 inches (7.6cm) larger than your current one. Prepare your new pot with gravel and cactus mix.

Carefully remove the String of Coins from its current pot. Shake off excess soil.

Check for any damaged roots and snip them off. Replant into your new pot. 


The String of Coins may get leggy or untidy as the branches grow long. Lightly prune trailing branches to maintain a neat shape. Snip off branches that are damaged or broken. In general, this plant requires minimal maintenance. 

Your String of Coins needs very little maintenance. If the trailing branches are becoming too long and scraggly, you can trim them off with a small cutter. 

Check for branches that may be broken or diseased and trim them off to prevent the rest of the plant from becoming infected.

1. Pest Control

This plant is not susceptible to pests. They may occasionally be attacked by scale insects.

Rubbing alcohol and a small cloth and rub directly onto the scale insects.

This will kill them, and you can then remove the scales gently by rubbing them with a dry cloth, by hand, or by picking them off with tweezers. 

2. Root Rot

Overwatering is the most common reason behind root rot in your String of Coins. This plant requires minimal water.

Ensure that you only water when your soil is dry. If your roots are rotting, remove the plant from its container, trim the bad roots, and replant it into a new pot with dry soil. 

3. Plant Starts Drooping

This is another sign of over-watering. If you examine your roots, you will probably find that they are rotting due to standing in too moist soil
