Hoya Care Basics
Propagating and Soil
I recommend propagating your hoya in perlite or tree fern fiber (or a mix of the two), stratum, or pon. If roots are already established or when roots become established (make sure roots are a few inches long before planting), an airy mix of medium is best. For example, Perlite, Orchid Mix, and Coco Husk (equal parts) work well for most hoya. Tree Fern Fiber and Perlite mixes can be used for both propagating and mature plants. Different mediums have different watering times, so be sure to do your research.

Repotting
When working with an already potted Hoya, plants only need to be repotted once every few years, unless a problem arises or you see signs that the plant has outgrown its pot. When potting cuttings, you should use a small pot, around 2-4 inches in diameter depending on if you are working with multiple cuttings and their size. Remember to have good drainage in your pot, or feel confident in your ability to remove excess water after watering.
Watering
If you are water propagating, be sure to change the water regularly to prevent rot and algae buildup. If your hoya is in some kind of medium, one of the best ways to tell if your hoya needs water is by paying attention to the leaves. If they look wrinkly or are not as firm as they were, it likely needs water. If they are mushy, then you have likely overwatered the plant.
Fertilizing
Give your plant time to adjust to its new environment before starting to fertilize your plant, a minimum of two weeks. If you are working with a propagation, avoid fertilizers, and opt for a rooting hormone. There are many types of fertilizers you can use, but I typically recommend orchid or hoya spray (applied when watered) and fertilizer balls 14-14-14.

Vines and Flowers
Hoyas produce vines that will eventually grow new leaves and hopefully with time, flowers. Some Hoya owners cut these when their plant has reached their desired size, but if you want your plant to continue to grow, let them grow. Hoya flowers grow on peduncles, which means it grows a separate stem dedicated to flowers. If your hoya does bloom, be sure to leave the peduncle alone, as it can continue to produce new flowers in the growing season and beyond!
