Hoya plants should be kept out of the high light of the day, as this may burn the leaves. They need bright light but indirect. Water the plant frequently enough in spring and summer that the soil is kept moist. Misting is also a good, Hoya in winter do not need as much water as in summer. Wait until the top few inches of soil are dry. Mist plants that are near drying furnaces or other heat sources several times a week to increase humidity
