H. cumingiana is a vigorous, scrambling, epiphytic shrub with broadly oval to rounded, fleshy, bright green leaves and, throughout summer, umbels of fragrant, pale yellow flowers with maroon coronas.
Hoyas should be fertilized monthly; The International Hoya Association suggests feeding them with a fertilizer that includes nitrogen, phosphorus, and potassium.
A well-draining, lightweight soil mix is what hoyas should be planted in. Too much moisture and the roots will rot.
When your hoya plant finishes blooming, leave the flower stalk, as it may produce new flowers. Removing the stalk forces the plant to produce a new stalk, which delays blooming and wastes the plant’s energy.
Hoyas like the security of a snug pot and plants that are a bit root-bound will flower more prolifically than those that are swimming around in a giant pot.
