Basic plant care for Hoya Australis

 

Hoya australis is a fast-growing climbing vine with trails up to 3m. It is an easy-to-care plant, and the air-purifying qualities make it a classic houseplant.

 

Soil

 

Choose a well-draining mixture for growing your Hoya australis. 

 

Fast draining and well-aerated compost are essential for the plant to thrive. You can create your own mixture using 1 part (by volume) peat-free compost, 1 part orchid bark, and 1 part coarse perlite.

 

A well-draining mixture will reduce overwatering damage and protect the plant from root-rot. 

 

Watering

 

This plant has low to medium water requirements. The succulent leaves will store water, so on average, water the plant every 10 days.

 

Monitor the soil using a moisture meter or check it manually before watering the plant. It is crucial to allow the upper half of the potting mix to dry out between watering.

 

In summer, the soil should be moist and hydrated but not waterlogged. When watering a Hoya australis, thoroughly saturate the soil until water flows out of the bottom of the pot. Rainwater or filtered is best for watering, especially in areas with hard water.

 

In winter, you should water the plant sparingly. It is always better to underwater Hoya plants than overwatering them. If overwatered, the lower leaves will start yellowing and even fall off.

 

Hoya australis will easily indicate under-watering through its leaves. If the leaves get crinkly, your plant needs a drink. And don’t worry; the leaves will get back to their original form after a good watering session.

 

Light

 

Based on where Hoyas originate from- tropical climates and how they grow –by climbing up trees, they need bright, dappled sunlight for growing and blooming.

 

Just like several other Hoya plants, Hoya australis also needs bright but indirect light and embraces the sun all year round. It will also enjoy some early morning or late afternoon direct sunshine.

 

This plant needs full sun, but to protect it from sunburns, I would suggest keeping the plant a few feet away from direct sun. Intense direct sunlight will damage and burn the leaves. Never place your Hoya australis in a drafty window.

 

Choose a spot close to a window with the right combination of sunlight and shade to create optimum growth conditions.

 

Keeping in good light will help the Hoya plant to not only grow better but also prevents the soil from staying too damp. You can always readjust your plant’s position based on its growth and behavior.

 

Hoya Australis can survive in low light, but it is unlikely to bloom under such conditions. It does well under artificial light, making it a suitable plant for small office spaces or places with minimal sunlight.

 

Humidity

 

Although Hoya Australis grows naturally in subtropical or tropical climates, it is now widely grown in different climates as an indoor plant. Therefore it is important to imitate the natural environment for healthy plant growth.

 

Hoya australis loves high humidity levels. However, it can also withstand low humidity levels with no harm, i.e., 40-60%.

 

To create a humid atmosphere, place the container on a gravel tray, expanded clay granules, or recycled lightweight aggregate. Keep the tray moist with water levels slightly lower than the gravel surface. Alternatively, you can also use a humidifier.

 

The growth rate depends on the Hoya species, but high humidity can really help accelerate growth.

 

Fertilizer

 

You can apply any general-purpose fertilizer during the summer season. Hoya australis is a light feeder, so fertilize it with ¼ teaspoon of fertilizer per gallon of water once a month. Use balanced fertilizer like a 15-15-15 or a blooming fertilizer like a 7-9-5.

 

Hoya australis stops growing in winter, so discontinue feeding.

 

You can also add a good quality commercial plant nutrition solution to encourage growth for Hoya plants. It will increase the fertility of the potting mixture. Simply dilute 5ml (1 teaspoon) of nutrition per liter of water. Spray or mist the mixture over the plant foliage.

 

I would suggest feeding Hoya australis monthly spring through fall with a high-potassium liquid fertilizer diluted by half. Many gardeners highly recommend using an organic fertilizer biweekly instead of a chemical one.
