How To Grow And Care For Hoya Krimson Queen

Hoya Krimson Queen Propagation from Stem Cutting

Hoya krimson queen is generally propagated by branch cutting. Although it can take root and germinate by leaf cutting, the growth rate of Hoya krimson queen propagation from stem cutting is too slow. You can cut off several branches about 7 ~ 9 cm long. Each section should have about two or three growth nodes, at least one node, otherwise it will not take root and germinate normally. Just like before Hoya krimson queen cutting propagation, you can dip a little rooting powder at the bottom of the branches. In addition, you should pay attention to preparing suitable soil. It is no different from Hoya krimson queen leaf cutting propagation.

Hoya Krimson Queen Propagation from Layering

Layering is the propagation method with the highest success rate of propagation. After Hoya krimson Queen's branches grow longer, a small section can be pressed into the soil. We should pay attention to the location of Hoya krimson queen propagation from layering. We must grow leaves at the growth node and roots at the other end. After that, prepare some paper clips, or fold one branch into two sections and bend it into a V shape. Press the growth node of Hoya krimson queen branch into the soil to cover a little soil properly. In the later stage, we should pay attention to watering regularly. In addition, we should pay attention to keeping the soil in the small seedling basin moist and the air moist, which can give a little scattered light every day.
