Hoya’s will provide beautiful, star-shaped blooms in the right environment. The blooming seasons are during Spring and Summer. Hoyas will not bloom if they do not have optimal light and water. Never overwater a Hoya but do not underwater either. Try to water your Hoya when it becomes dry a few inches beneath the soil. As for light, a Hoya needs bright, indirect sunlight. If your Hoya is not blooming during the active seasons, try to locate a sunnier spot indoors.
