Hoya - “Wax Plant”
Light: Hoyas like a range of light: from bright indirect light, to being exposed to a few hours of direct sun. So placing them in or near an east, west or southern window is ideal. In order to bloom they need at least four hours of bright light a day.
Water: Hoyas are a type of succulent, so allow the soil to dry out before watering. Depending on the size of the plant and your environment, this could take 1-2 weeks in the summer and 2-3 weeks in the winter. They require well aerated, fast draining soil and a vessel that has a hole in the bottom for water to drain through is ideal. Using room-temperature water that has been “aged” or left sitting in an open container for at least 24 to 36 hours is beneficial. Hoya plants are epiphytic tropical plants that could be stressed by cold tap water.
Environment: Hoya plants can adapt to almost any moderate temperature, but prefer 60°- 65° at night and 70°- 80° during the day. Be sure to keep them away from drafty windows or doorways.
They like to climb, so it's suggested to plant them in a hanging pot or near something the plant can climb on. They grow particularly well over a trellis or around a window.
*When planting in a pot without a drainage hole, avoid over watering by estimating 25% of the container’s overall volume, with appropriate drainage materials incorporated when planting.
