How to propagate string of hearts
Ceropegia woodii
Propagate string of hearts by stem cutting. Roots in 14 to 28 days in water. The cutting must include a node.
Why stem cutting works here
Roots form at the node — the slightly swollen point where a leaf meets the stem. That tissue can still turn into root tissue; the smooth stem between nodes cannot.
Doing it
Cut a few millimetres below a node with at least one leaf above it. Strip anything that would sit underwater. Put the node in the medium, the leaf in the light.
Where it goes wrong
A cutting with no node will sit green for weeks and then rot. It is the commonest way to waste a month.
The other routes
Slower or lower-yield for this species, but each has a case.
layering
A trailing stem left in contact with soil roots at the nodes on its own. You are just encouraging what it already does. Nothing much. It is the lowest-risk method there is, and the slowest.
tuber division
The storage organ can be cut so that each piece carries at least one growth point. Rot at the cut. This is the riskiest method here, and buying a second plant is often the better trade.
Before you cut
- Sap is not a concern here. String of hearts is listed non-toxic to cats and dogs, so offcuts and rooting jars are lower risk than with most houseplants.
- Take more than you need. Losses are normal. Three cuttings in one jar costs nothing extra and changes the odds.
- Use a clean blade. Scissors crush the stem and crushed tissue rots. A craft knife wiped with alcohol is enough.
- Do not fertilise a cutting. There are no roots to take it up, and the salts sit in the medium and burn what does form.

Rooting times are typical ranges for indoor conditions, not guarantees. Warmth and
light move them more than anything you do to the cutting. How this is sourced.
