How to Grow and Care for Hoya Plants

Hoya plants also known as wax plants or porcelain flowers, are beloved for their beautiful foliage and unique, waxy flowers. These tropical plants are relatively easy to care for and can thrive both indoors and outdoors. This article provides a comprehensive guide on growing and caring for Hoya plants, enabling you to cultivate these stunning additions to your home or garden.

Choosing the Right Hoya Plant

Hoya Varieties

There are numerous Hoya plant varieties to choose from, each with its distinctive characteristics and growth requirements. Some popular varieties include Hoya carnosa, Hoya kerrii, and Hoya pubicalyx. Consider your preferences and the conditions in your environment when selecting the right Hoya plant for you.

Sourcing Hoya Plants

Hoya plants can be obtained from local nurseries, online plant retailers, or through plant exchanges. Ensure that the plants you choose are healthy, pest-free, and preferably in their blooming season to enjoy their beautiful flowers sooner.

Ideal Growing Conditions


Hoya plants thrive in bright, indirect light. Place them near a window with filtered sunlight or use artificial grow lights to provide them with the necessary light intensity. Avoid exposing Hoyas to direct sunlight, as it can scorch their leaves.

Temperature and Humidity

Hoya plants prefer temperatures between 60°F and 80°F (15°C and 27°C). They are not frost-tolerant and should be protected from cold drafts. Additionally, maintaining a humidity level of around 40-60% will help plants thrive. Consider using a humidifier or placing the plant on a pebble tray to increase humidity.

Soil and Potting

Use a well-draining potting mix specifically formulated for tropical plants. A mix consisting of peat moss, perlite, and orchid bark is ideal for Hoya plants. Ensure that the pot has drainage holes to prevent waterlogging, which can lead to root rot.

Watering and Feeding


Plants prefer to be slightly under-watered than over-watered. Allow the top inch of the soil to dry out between waterings, and then water the plant thoroughly. Avoid letting the plant sit in standing water, as it can cause root rot. Adjust the watering frequency according to the season and the plant’s specific needs.


Feed your plant with a balanced, water-soluble fertilizer diluted to half the recommended strength. Apply the fertilizer during the growing season (spring and summer) every two to three weeks. Reduce or cease fertilization during the winter when the plant is in its dormant phase.

Pruning and Maintenance


Regular pruning helps maintain the shape and health of your plant. Remove any dead, damaged, or yellowing leaves and stems. Additionally, you can trim back overgrown vines to encourage bushier growth and stimulate more flower production.

Support and Training

The plants are climbers, and they will produce long vines that need support. You can use trellises, stakes, or moss poles to guide the vines and encourage upward growth. Gently train the vines around the support structure to create an aesthetically pleasing display.


Propagation Methods

The plants can be propagated through stem cuttings, leaf cuttings, or by layering. Stem cuttings are the most common method and involve taking a healthy stem with a few leaves and rooting it in water or a well-draining potting mix.
