String of Hearts (Ceropegia woodii) is one of those houseplants that seems to have propagation built into its nature. Its delicate trailing stems can be turned into new plants in several different ways, making it an excellent choice if you are new to propagation or simply want to make your existing plant even fuller.
There are three reliable ways to propagate String of Hearts. You can lay a strand directly onto soil using the butterfly method, root stem cuttings in water, or make use of the small aerial tubers that develop along established vines. Soil propagation is our preferred method because it is simple and avoids the transition from water roots to compost, while water propagation is particularly satisfying if you enjoy watching roots develop. The aerial tubers are even easier, giving you ready-made little propagation points with very little effort.
Whichever method you choose, the most important thing is knowing where to cut. String of Hearts has delicate stems, and you need to include a node for roots and new growth to develop. Here is how to propagate Ceropegia woodii using all three methods.
Method One: The Butterfly Method
The butterfly method is our first choice for propagating String of Hearts because it allows several sections of one vine to root at the same time. Rather than planting individual cuttings, you lay sections of the vine directly onto the surface of the compost, encouraging roots to develop from the nodes.
Take a healthy strand and cut it into sections, making sure each section contains at least two pairs of leaves. The points between the pairs of leaves are the nodes, and this is where new roots will form.
- Lay each section flat across the surface of a moist, free-draining mix, keeping the leaves facing upwards.
- Gently press the nodes against the compost so they have good contact with the surface. You can also use a bent paperclip to hold the vine in place.
- Keep the compost lightly moist and place the pot somewhere warm with bright, indirect light.
Within a few weeks, roots should begin developing from the nodes. Because several sections of the same vine can be rooted at once, the butterfly method can produce a much fuller plant than rooting individual cuttings separately.
Method Two: Propagating String of Hearts in Water
If you prefer to see your propagation progress, water rooting is a simple and rewarding option. Start by taking healthy cuttings around 10 to 15cm long and remove the leaves from the lowest one or two pairs.
Place the bare nodes into a small glass of water, allowing the leaves to sit above the surface. Keep the glass somewhere warm with bright, indirect light and top up the water as needed. Change the water every few days to keep it fresh and reduce the risk of the cutting becoming soft or rotten.
Roots usually begin to appear within two to three weeks. Once they have reached a couple of centimetres in length, move the cutting into a free-draining potting mix. Try not to leave it in water for too long, as water-grown roots are delicate and can find the transition into compost more difficult if they become overly established.
Method Three: Propagating from Aerial Tubers
One of the easiest ways to propagate an established String of Hearts is to use the small, firm tubers that naturally develop along the vines. These bead-like structures are sometimes referred to as the pearls or beads of the plant, and they can produce new roots and shoots.
Rather than removing the tuber straight away, leave it attached to the parent plant and gently rest it on the surface of a nearby pot filled with moist, free-draining compost. The tuber can then develop roots while it is still connected to the parent plant.
Once it has rooted and begun producing fresh growth, you can snip the connecting stem and allow your new plant to grow independently. This is arguably the easiest propagation method of all, as the plant does much of the work for you.
How Long Does String of Hearts Propagation Take?
Under warm, bright conditions, you can usually expect to see roots developing within two to three weeks. A young plant can become visibly established within one to two months, although the exact timing will depend on the method you use and the conditions in your home.
Spring and summer are the best times to propagate, as warmer temperatures and longer days encourage faster growth. Propagation naturally slows during the darker, cooler months. If you want to continue propagating through winter, a heat mat can help maintain the warmth needed for root development.
Common Mistakes When Propagating String of Hearts
The most common mistake is taking a cutting without a node. Roots and new growth need to develop from a node, so cutting between leaf pairs can leave you with a piece of vine that has nowhere to root. Before making any cuts, it is worth familiarising yourself with what a node is and why it matters for propagation.
If your water cuttings become soft or mushy, the stems may be sitting too deeply in the water or the water may not be fresh enough. Our guide to why cuttings rot in water explains what causes the problem and how to prevent it.
You can also skip water propagation altogether and plant your cuttings directly into compost. If you would rather avoid water rooting, see our guide to propagating houseplants directly in soil.
Once you have a healthy parent plant, String of Hearts propagation is wonderfully forgiving. A few carefully placed cuttings can quickly turn a sparse-looking pot into a much fuller display, and those little aerial tubers mean your plant may even start doing the propagating for you.
