The string of hearts (Ceropegia woodii) is an evergreen vine from South Africa and Zimbabwe. This plant is often grown as a hanging plant or trained to grow up a trellis. In the wild, it grows up plants, using them as a living trellis. If you are thinking of growing a string of hearts vine, you may wonder, “What kind of soil does string of hearts need?”
When growing a new plant, it is always tricky figuring out what soil mix they will grow best in. This guide will help you make that decision.
What Kind of Soil Does the String of Hearts Need?
String of hearts needs a fast-draining soil. A commercial cactus and succulent potting mix will work well. You can mix your own soil from perlite, sand, and a regular potting mix. You can use one part coco coir and one part pumice instead of a commercial mix.

String of Hearts Potting Soil Requirements
The string of hearts has to have well-draining soil. The roots and tubers will rot otherwise. You can use a commercial potting soil for cactus and succulents. This soil mix has the advantage of being easy to find and ready right out of the bag.
Use the same soil for a variegated string of hearts (C. woodii f. Variegata) as for the regular string of hearts. Both string of hearts types prefer a soil pH that is acidic or neutral.
String of Hearts Potting Soil Recipes
If you prefer to mix your own soil mix for your string of hearts, there are several recipes you can use. Here are a few of the most common.
- Three parts cactus potting mix
- One part coco coir
- Two parts pumice
If you can’t find cactus potting soil, you can use a regular indoor plant potting mix with this recipe.
- One part regular potting mix
- One part perlite
- One part sand
This recipe does not use any potting mix.
- One part coco coir
- One part pumice
Coco coir is the fibrous material on the coconut and is a by-product of the coconut industry. Use the ground coco coir for these recipes.
Type of Planters for String of Hearts
In addition to the right potting mix, you need to put your string of hearts plant in the correct type of pot. First, make sure any pot or planter you use has drainage holes.
Although the vines can get quite long, the actual crown and root system is small, two to four centimeters tall. Place your string of hearts in a small hanging basket about one inch in diameter larger than your plant.
If you are training your string of hearts to grow up a trellis, choose a shallow pot or planter that is about six inches deep.
Repotting String of Hearts
You should repot the string of hearts every year.
If the crown of the plant is growing bigger, go up in pot size by one inch. If the crown of the plant is the size you want, remove the plant, discard the used potting mix, and use new potting mix with the same pot. Repot in the spring.
Pruning String of Hearts
A good time to prune the string of hearts is when you repot it. Cutting the vines back will result in vigorous vine growth during the spring and summer. Save the trimmings from the vines to start new plants.
Propagating String of Hearts
The soil for the propagation of the string of hearts is the same as the regular potting mix. You can propagate the string of hearts in three ways: from seed, tubers, or cuttings.
Plant the seed in a fresh pot of potting mix. Just cover it with soil. Keep the soil moist but not soggy until the seedling has become established, then transition to a regular watering schedule.
Another name for the string of hearts plant is the rosary vine. Bead-like tubers form on the vines. To propagate the plant, place a tuber in a pot while it is still attached to the parent plant. Do not bury the tuber. When roots are established, cut the tuber away from the parent plant after about eight weeks.
All those vines you cut back can be used to grow new plants. Take a four to six-inch cutting and put it in the potting mix. Water the cutting in. Water once a week for about eight weeks until the plant is established, then transition to a regular watering schedule.
Before planting a string of hearts plant in new potting mix, soak the potting mix in water overnight. Coco Coir may have trouble absorbing water otherwise. After the initial wetting, let two-thirds of the pot’s soil dry out between waterings in the spring and summer.
In the fall and winter, let the ground in the pot get almost completely dry before watering. Overwatering will cause root rot. When watering, water until water runs out of the drainage holes. Let sit for fifteen minutes, then empty any water in the pot’s saucer.
