FAQs about Hoya Plant
Why isn’t my hoya blooming?
Hoyas require bright, indirect light and time to mature. Some won’t bloom for a few years. Make sure not to remove the flower spurs, as new blooms grow from them.
Can I grow hoya in low light?
While hoyas tolerate low light, they grow and flower best in bright, indirect light. In low light, growth slows and blooming is unlikely.
How do I propagate a hoya plant?
Propagate by taking stem cuttings with at least one node. Place the cutting in water or soil until roots form, then transplant.
