Hoya Care

Hoya plants are tropical vining plants which are often called as wax plants because of the thick and waxy texture of the foliage These tropical plants have few requirements to be fulfilled in order to become a good house plant.


Though the leaves of the Hoya plants are thick and waxy it does not mean that they are succulents. They should be kept away from direct and bright sunlight. Find a place where the plants could get indirect sunlight.


Potting soil with good air circulation is very important for Hoya. To create a perfect blend, mix equal parts of organic Cactus Mix, Orchid Mix, and Perlite. Hoya like to be pot-bound or crowded in their pots. They will only need to be re potted every two or three years.


Water the Hoya plants with normal room temperature water throughout the seasons. Do not water much during winters and fall as the growth potential is low during that time. Pour enough water to keep the soil moist but remember not to over water as it may cause the flowers to drop.


Temperature and Humidity

These tropical plants thrive best in humid conditions. Maintain enough humidity during winter as the air becomes dry during that time. You can use a humidifier to maintain the moisture level. Temperature should be less than 16° C. It’s also best to keep plants from touching cold windows and away from heating and cooling vents.


Hoya does not require much fertilizer. Liquid fertiliser is considered to be the best when it comes to feed Hoya. Fertilise every once in a month and that would be enough for its growth.
