Hoya Nummularioides Light

They need bright indirect light to thrive. Direct sunlight can burn the leaves so be careful. They will do ok further back from the window in medium light but may flower less often.

How Often To Water?

Check the soil weekly and only water it if totally dry. Hoyas need to dry out like cacti, and similarly can be overwatered easily. They grow in tree bark in the wild, up in the branches, and do not grow in the ground in wet soil, so keep this in mind before drenching them.


Do not feed in winter, but you can use a high in phosphorous feed while they are blooming and before, if you can time it right, to encourage flowers. The rest of the year you can use a balanced feed every month, making sure it is well diluted.


A mix of cactus soil, perlite and orchid bark is a great mix for hoyas. For more on hoya soil see our guide here: Hoya Soil.

When To Repot?

Hoyas are ok to be root bound a bit, so you can wait to repot them see roots growing out of the drainage holes on the bottom of the pot. They will grow quicker if the roots are given space to grow. The best time to repot is during spring or summer when the plant is growing.


Aim for humidity of 50% or more. Increase humidity by placing the plant on a pebble tray or grouping plants together.


Aim for 18-26°C (64-79°F) during the day and no lower than 10°C (50°F).
