Introduction

The hoya australis is originally from Australia, and is now a worldwide houseplant with many sub-varieties that are becoming increasingly popular.

Light Needs

Bright indirect sunlight is idea. They grow fairly slowly and need as much help as they can get!

How Often To Water A Hoya Australis

It is really important not to over water a hoya, they do not grow in soil in the ground, they grow in trees in bark in the wild, so make sure you do not let them sit in wet soil. So check it weekly and water it only if the soil is dry.

Fertilizer

Use a balanced fertilizer once a month in the growing months. It will encourage leaf and bloom growth.

Soil

As mentioned these plants are epiphytes and grow up in trees in bark, so you want to give them a soil that imitates their natural habitat as much as possible. I use equal parts soil, perlite and orchid bark.

When To Repot Hoya Australis

They are OK to be pot bound a bit, but check them yearly and give them a new pot if they are too crowded.

Humidity

60% is ideal, they do just fine at 50% though.

Temperature

They are fairly tough when it comes to temperature and can survive low temperatures at night, but aim for a normal range of 15-28°C (59-82°F).

How To Propagate Hoya Australis

Propagate a hoya australis by taking stem cuttings and rooting them in water until you get a good amount of healthy roots, then you can pot them up into a good hoya mix. You’ll need a section of stem with at least two or three nodes, and take the leaves off the bottom node so that there are no leaves in the water.

FAQs And Common Problems

Root rot from overwatering is a common issue with these hoyas. Do not water them until dry and don’t leave water in the saucer or external container. Keep them in a really well draining medium too so the soil does not get waterlogged easily.
