Recently several clients received wax plants (hoya plants) with very long vines. One of the best ways to propagate wax plants is from a growing vine without cutting the vine first. It’s the dip the vine in dirt method which is easy and usually 100% successful. This method of propagate is for wax plants you already own. Yes, you can air layer long hoya plant vines too, however, it takes longer and you need to make sure the area stays moist. We use three methods of propagation of hoya plants: air layer, vine dipping and cuttings planting. By far the best way is to use wax plant vine dipping.
The only problem with vine dipping is that you need room in the same pot as the parent plant. Yes, you can stretch the wax plant vine into another pot, however, now you have two pots to water.
How to Propagate Wax plants From Vines
How to do it step by step: 1) Get a piece of wire about 6..8 inches long an bend into a U-shape to hold the vine in the soil or a rock with enough weight to keep the vine in contact with the soil, 2) Select a vine section with at least 3..4″ of length beyond where you want to create the new plant. 3) Place/dip the wax plant vine in or on top of the soil in the same pot as the parent plant. Do not cut the vine! 4) Use the wire or rock to hold down the hoya plant vine and 5) wait a couple months for roots to grow.
It’s simple and easy. Plus, its 100% successful as long as your main plant is healthy. The actual time it takes the hoya plant to grow roots will depending upon the season and size of the parent plant. Consider using fertilizer, such as, Dyna-Gro Gro and even use Dyna-Gro K-L-N the first month.
