Stem layering

On an adult plant, the strongest shoot is chosen, a 1 cm long incision is made on it, wrapped in wet moss, then tied with a film.

As soon as the roots break through the moss, they remove the bandage, cut off the shoot from the mother plant, and plant it in a mixture of peat and sand mixed in the same proportion.


This is the most popular method used by flower growers. Cuttings are cut in the spring or summer during the active growth phase. Cut off segments 15-20 cm long with 2-3 leaves and buds. All the leaves are cut off from below, dipped in Kornevin's solution for half an hour. Then they are planted to a depth of 3 cm in a peat-sandy substrate.

For fast rooting, cuttings are provided with stable heat within 23-25 ​​° C and regular moisture. As soon as they release 2 pairs of leaves, they are seated in separate flowerpots.


Several thick and adult leaves with axillary buds are selected, pinched off the stem, dipped in Kornevin's solution, planted in a peat-sand mixture. To make them take root faster, they are covered with transparent film or glass. Ventilate daily, moisten as the substrate dries.
