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.
