Light Needs

Bright indirect sunlight is best. They will be fine in medium light to be honest, further back from 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 every 3 or 4 weeks in the spring and summer months. They’ll be ok if you don’t feed them, but can grow quicker and fuller if you do.

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 as much as you can, they do not want to sit in wet, water logged soil.

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, they will be ok in less, but will thrive if give 60% or more, it can really help to encourage growth and blooming.


Aim for a daytime temperature of 15-28°C (59-82°F). Try to keep it above 10°C (50°F), as minimum temperature at night or in the winter.

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.
