How to Propagate Euphorbia lactea ‘Cristata’
Euphorbia lactea ‘Cristata’ is not easily propagated. The crested Euphorbia lactea is grafted onto the root stock of Euphorbia neriifolia or sometimes Euphorbia canariensis. The best time to graft your succulent will be in the Summer, when it is actively growing.
Caution: Euphorbias contain a toxic latex sap that can cause irritation. Please use gloves and goggles when handling this succulent.
After selecting a healthy root stock, cut a “V” into the top of the plant. Trim the stem of ‘Cristata’ to form an arrow. Places the two succulents together, and secure them together with twine or butcher’s string.
Allow the plant to sit in a warm room with bright sunlight for several weeks. Check your graft after this time; if the plants have healed and joined, you can carefully move it to where you will be growing it. Water as usual.
If the graft looks like it has not completely healed, tie fresh twine around it, and allow it to sit for another week or two.
Cristata is Latin for “crested.”
