1 Light: Hibiscus are full-sun plants. Lack of sunlight can cause overall yellowing of the leaves. On the other hand, if the plant is getting sunburned, the leaves can get yellow or white splotches.  Insect Infestation: Spider mites and aphids are two major pests of hibiscus that can cause leaf damage and discoloration.
Tropical hibiscus plants hate temperatures below 45 degrees, and die when temperatures are 25 degrees or lower. So if you want to winter over a tropical hibiscus, here's what to do: â¢Prune it back. Hibiscus can be cut back by up to 50 percent, although 30 percent is more usual. Trim the stems leaving a bit of new growth and several mature leaves on the plant. â¢Mature tropical hibiscus plants thrive in 10- to 12-inch pot.
