FAQ

What Should I Do to Help My Hoya Houseplants Get Flowers?

Indoors, hoya plants need to be about 3 years old and sit in very bright light in order to bloom. Never cut off the older stems because that is where the flowers will grow.

Should I Prune the Old Stems Off My Hoya to Encourage New Growth?

Not a good idea!! New flowers develop on the old flower stems of a hoya plant so never cut off the old stems.

How Do I Get Rid of Mealy Bugs on My Hoya? I Have a Beautiful Plant With Long Vines Twisted Around Each Other. The Plant Has Mealy Bugs and No Matter How Much I Spray They Keep Coming Back in Areas I Can’t Seem to Reach.

You can try to get rid of Mealy Bugs on hoya plants by spraying the entire plant with the ” green solution” (8oz. water & 8oz. alcohol, add two tablespoons of biodegradable soap and two tablespoons of mineral oil). You can read more about this simple remedy in the Glossary of the website. You can also purchase a very small pesticide bomb at your local nursery. Place your plant in a plastic bag, release the bomb, and seal the plastic bag. Leave your Hoya in the bag for 24 hours. I prefer the ” green solution” since it doesn’t use chemicals.
