Propagation of Cacti and Succulents: Which Method for What Species?

0

Sometimes it is very easy to identify the best way to propagate a cactus or succulent, and other times it is not as obvious. However before you start, the first thing to ask yourself is: What kind of plant do I have? If you don’t know the easiest way to learn is to organize the information you know about your plant into categories. How is it shaped? Is it tall and thin, short and round, or does it have many little leaves? How does it grow? Does it grow all by itself, are there many branches, or are there similar tiny plants that poke up out of the soil near it? Does it flower?

Questions like these are the first ones to ask your self when considering propagation. The next thing to think about is how to propagate your cactus or succulent.

Seeds

Most cacti can be propagated by seed; however due to the slow growth of some species, sometimes other methods are more practical. Cacti with solitary growth habits are usually propagated by seed. Several species grow in this manner including:

  • Notocactus spp. (now included in the genus Parodia)
  • Neoporteria spp. (now included in the genus Eriosyce).

Stem Cuttings

Propagation by stem cuttings is easy and practical. Many cacti and succulents can be propagated by stem cuttings.  In general, if the plant has an elongated stem region that is actively growing, propagation by stem cuttings should be a successful route. Some recommendations are:

Leaf Cuttings

Most succulents are usually propagated by leaf cuttings. Genera typically propagated by leaf cuttings include but are not limited to:

Grafting

Grafting requires a hardy rootstock which is compatible with the desired propagation candidate. This compatibility is very important. Without it, success in grafting in unlikely. For cacti and succulents the following rules and some successful grafts have been reported and are shown below:

Bulbils, Tubers, Plantlets, and Offsets

Many succulents asexually propagate been means of underground lateral shoots. These shoots give rise to offsets or plantlets which can be severed in the spring or summer from the parent lateral shoot to produce a self-sustaining new plant. Aloe spp. and some Agave spp. form plantlets or bulbils on their flowing stalks. These plantlets and bulbils can be removed and planted as well. Kalanchoe spp. produce small plantlets on the scalloped edges of their leaves. These plantlets can also be potted in warm conditions to produce self-sustaining plants.

  • Bulbils and Plantlets: Kalanchoe, Aloe, Agave murpheyi, Agave vilmoriniana, Agave fourcroydes
  • Offsets: Echinopsis, Mammillaria, Agave, Aloe, Haworthia, Crassulaceae family, Kalanchoe, Sedum, Graptopetalum
  • Tubers: Ceropegia.
