How to care for the Wax plant

Our tips for helping it grow healthy and strong

Hoya carnosa, also known as the Wax plant, is a semi-succulent evergreen climbing plant that captivates with its waxy leaves and fragrant flowers. In our nursery, we consider it an excellent choice for anyone looking for an indoor plant that combines beauty with ease of care.

The right spot

The Wax plant enjoys bright light, but it is important to protect it from direct summer sun, which could damage its leaves. A spot with filtered light is ideal for promoting lush growth and abundant flowering.

When and how to water it

To keep your Hoya carnosa healthy, it is essential to water it thoroughly until the excess drains away. In winter, wait until the compost is fairly dry before watering, but do not let it dry out completely. This will help prevent root rot.

Temperature and humidity

Hoya carnosa thrives in an environment with temperatures between 16°C and 24°C. It enjoys a humid atmosphere, so if the air is too dry, consider increasing the ambient humidity for its well-being.

The right fertilizer

During spring and summer, we recommend feeding your plant every 14 days with a balanced fertilizer for orchids, preferably without urea. This supports growth and flowering.

The pot and soil

For the wax plant, choose a very well-draining, well-aerated compost. A mixture of orchid compost, peat-free multipurpose compost, and coarse material is ideal for ensuring good drainage and adequate root aeration.

How to propagate it

Hoya carnosa can be successfully propagated by air layering or semi-ripe cuttings, preferably in spring or early summer. These methods allow you to obtain new, vigorous, healthy plants.

Our final advice

Hoya carnosa is a plant that rewards patience with spectacular blooms. Give it consistent care and a suitable environment, and it will treat you to moments of beauty and fragrance. Don't forget to inspect it regularly to prevent mealybug infestations.
