Bright indirect sunlight is best. They will be ine in medium light to be honest, further back form the window, but they may flower less.

Tip: give it plenty of light to encourage flowering.

How Often To Water

Check the soil once a week and water it when dry. You want to let hoyas dry out as they are epiphytic by nature, which means they live on trees in the wild and root in bark. So they really do not want to sit in soggy soil.


Use a well diluted balanced feed once a month in spring and summer.

Hoya Lacunosa Soil

A mix of equal parts soil, perlite and orchid bark is best, it will stop it getting too soggy and avoid root rot. You want to mimic their natural environment of living in tree bark well.

When To Repot

Check the roots once a year and pot them up if the roots have started to get crowded. They are ok if a little crowded, but heavy root crowding can slow growth.


60% is ideal.


Aim for 15-28°C (59-82°F).

How To Propagate Hoya Lacunosa

You want to take a cutting with at least 2 nodes (the joints where the leaves grow from),. Take the leaves form the bottom node and put it in jar of sphagnum moss so that the bottom naked node is under the moss and the leafy node is above the surface. Keep it humidity, warm and bright and it will root over two months, and when it stats growing new foliage you can pot it up in to a hoya potting mix.
