The genus Yucca brings together about fifty species. Yuccas are grown as houseplants, but they enjoy being set up outdoors as long as they can get plenty of sunlight. We love them exotic look and more their sculptural flowers in the form of bells. The hardiest species can withstand up to -20 ° C without difficulty, and all Yuccas are plants without special needs, ideal for structure rocky massifs. You might as well know when and how to cut a Yucca to multiply at leisure this easy-going plant with spectacular flowering. Let’s do a check in.
Ideal time to cut a yucca and method of cuttings
It is in spring that it is preferable to carry out the cuttings of a Yucca, when the recovery of the vegetation has begun.
In a single intervention, we realize a head cutting and one or several trunk cuttings. This does not pose any particular difficulty and success is almost guaranteed if the following few steps are respected.
- Select a vigorous stipe (false trunk) or a beautiful branching,
- Cut with a saw 30 cm above ground level. The mother plant must therefore retain part of the stipe which will produce new lateral shoots.
- Saw the part removed in several sections so as to have:
- a top cutting (upper sections) of 50 cm,
- several trunk cuttings of about 15 cm each.
- Make a pencil mark on each cutting so that you can distinguish the top from the bottom when potting.
- Put the cuttings aside and allow a drying time before applying a putty.
It is advisable to move on to the preparation of the pots, knowing that a container with pierced bottom by section.
- Place a few shards of terracotta at the bottom of each pot to prevent the substrate from leaking through the hole.
- Place a bed of clay balls or gravel in the pots to ensure a good drainage.
- Fill the pots with a substrate suitable for yucca cuttings.
- Make a hole in the center of the substrate and plant each section in it, taking care to respect the direction indicated previously in pencil.
- Either 1/3 of sand, 1/3 of potting soil and 1/3 of vermiculite,
- Or 50% coarse river sand and 50% leaf mold,
- Or 100% leaf mold.
It remains only to install the cuttings of Yucca in an extremely luminous and hot enough.
Successful yucca cuttings for sure
It is very important to let the sections dry for a few hours to one or two days and then coat their ends with a healing balm or from agricultural putty, or even failing that, tar. This allows to protect pruning wounds and limit the risk of rotting.
About the choice of substrate, it is essential to offer your Yucca cuttings a nutritious mixture. Three solutions are available to the gardener, namely:
We advise to wait a few days after planting to carry out the first watering. Thus, the healing balm has time to dry perfectly. If you are in too much of a hurry to water, you simply risk exposing your Yuccas to the risk of rot.
Finally, when each stump has formed a few leaves, it should be repotted in a potting soil for Mediterranean plants and in a pot a little larger than the previous one, always with the bottom pierced so that the roots of the young Yuccas do not bathe in the water. But it is also possible to transplant them in the ground, in a corner of the garden that is well suited to them, namely warm and bright. And to give Yucca cuttings a boost, a few liquid fertilizer applications are welcome.
