Sweetheart Hoya Sunlight Requirements

Sweetheart Hoya prefers bright indirect sunlight but will survive in lower light conditions. This plant does not tolerate full or direct sun. Place it in a south- or west-facing window. 

Sweetheart Hoya Care

Sweetheart Hoya can be particular about its growing conditions. It requires well-drained soil and performs best in a cactus soil mixed with a bit of orchid mix; select a pot with a drainage hole. Do not repot when flowering; Sweetheart Hoya likes to be pot bound and does not need repotting regularly. Do not trim or prune off the bare vines if you want Sweetheart Hoya to flower. Bright light encourages flowering. Sweetheart Hoya prefers warmer temperatures from 65-80 degrees Fahrenheit.

Watering Sweetheart Hoya 

Sweetheart Hoya is drought tolerant with low water needs. Water Sweetheart Hoya thoroughly once or twice a month, allowing the soil to dry out completely between waterings. Sweetheart Hoya has moderate humidity needs and typically does not need additional humidity in the home. 

Feeding Sweetheart Hoya

Sweetheart Hoya is a light feeder and can be fed with a balanced, gentle houseplant fertilizer one time a month. Do not apply fertilizer in the winter while the plant is dormant.
