Growing condition of Hoya plants

Soil and Location

For this, well-drained soil is required. You can use the orchid potting mixture or the homemade potting mix with lots of perlites. Wax plants are epiphytic and do not require heavy, more conventional soil. To develop this, the mixture of pine bark, perlite, and peat moss is most suitable. The most popular mixture is that one portion of pine bark and two parts of Pete Moss, in which a small quantity of dolomitic lime is added, this mixture reduces acidity. You can add perlite to increase its drainage capacity.

Hoya carnosa likes bright and indirect light, although they can tolerate full sunlight in spring or fall, the excessive summer sun can damage its lush leaves and lose its natural color. If you want to develop the Hoya Plant, it is necessary to light up at least 6 hours of bright and indirect sunlight.


Hoya plants are tropical plants that can be given water by cold tap. When potting soil almost completely dries, then water the plant. Give the plant water early in the morning, so that the plant will get adequate moisture throughout the day, but also make sure the leaves dry out by night. Pour the water in the pot normally, until it starts moving out of the surface. Do not allow the soil to wet due to excessive water, because its roots prefer oxygen and its deficiency can root rot.


During spring and summer, you feed your plant in a balanced and water-soluble fertilizer every three to four weeks. Fertilizer with a ratio of 5-10-5, 8-8-8, or 10-10-10 is most suitable for it. Depending on the plant’s health and the nature of bloom, you give fertilizer to your plant. If its leaves and stems start to yellow, fertilizer should be given every two weeks. If fresh leaves remain small and deep, then give Hoya fertilizer every six weeks. Read more.


The easiest way to propagate by either stem cutting or air-layering, but many people also propagate it through leaf cuttings or seeds.
