Light Needs

Give it bright indirect sunlight to encourage growth and blooming.

How Often To Water

Check it once a week and water only when the soil is dry all the way down. They really must not get overwatered. It is a good idea to wait ten minutes after watering and then tip out any water that is left over in the saucer.

Tip: make sure you do not water the plant until the soil is completely dry all the way down, as the biggest killer of hoyas is root rot. If in doubt, underwater it!

Fertilizer

A well diluted balanced feed once a month in spring and summer will encourage growth and flowering.

Soil

A cactus mix mixed with the same amount of orchid mix. It must be really well draining, as hoyas grow in bark in the wild, not in soil. For more on hoya soil (what to buy and how to make your own) see our guide here: Hoya Soil.

Tip: make sure you give them a soil mix suitable for epiphytes that has plenty of orchid bark, as they hate to sit in heavy wet soil and will get root rot easily. Remember that they grow on tree bark in the wild and not in soil. For more info see our guide: Hoya Soil.

When To Repot

If it’s roots are getting crowded, repot at easter time, before the spring and summer growing season. you can take it out of it’s pot to check it if unsure.

Humidity

A hoya fungii will thrive if given good humidity levels. Aim for 50% or above. They are not fussy when it comes to humidity, but giving the the right conditions can really help the plant flourish.

Temperature

Hoyas do well in most homes, the best range is 15-28°C (59-82°F).

Hoya Fungii Propagation

You can propagate hoya fungii by taking stem cuttings. Each cutting needs at least two nodes: one node which you take the leaves off and which will be under the water/soil, and another that will keep the leaves on it and be above the surface. You can root the cutting in water or soil, keeping it humid for a couple of months. They are slow growing but they should root, and then you can pot them up separately.

FAQ And Common Problems

The biggest killer of hoyas is root rot from overwatering as they are really sensitive to sitting in wet soil. They must be grown in a well draining potting medium, and only watered when the soil is totally dry.

Another issue is that they do not bloom. The best way to get them to flower is to give them plenty of indirect sunlight, and meet their other care needs, like watering well but not overwatering.
