It is important to note that Hoya australis plants are not suitable for use in cold-climate areas. If grown outdoors, these Hoya varieties should be placed in a warm and sheltered location with plenty of space around the plant so it can grow freely without harsh competition from other nearby plants.

Additionally, Hoyas require adequate sunlight. Hoya australis plants should not be grown in shady areas.

This Hoya australis was given to me by a friend, and I didn’t know much about it.

Hoya is the genus name for over 200 species of attractive vines or shrubs, all with showy five-petaled flowers. Most Hoya plants are tropical evergreens that thrive in low light indoors when kept on the windowsill. This plant is a beautiful plant that can grow to about 30 inches in height and has glossy, waxy leaves with white edges. This Hoya does well indoors as long as it’s provided enough light – I put mine near my window so the sun hits just one side of it for three hours per day.

How do you care for a hoya australis?

Hoya australis

  • Water the plant with room temperature water. It should not be too cold or hot, as this may cause harm to the Hoya australis (remember that they hail from a relatively warm climate).
  • If you notice any signs of rot, remove all infected parts and discard them in your outdoor garbage bin for safe disposal. This will prevent the rot from spreading to your other plants.
  • Fertilize with a water-soluble fertilizer monthly at half strength (or as recommended by the manufacturer) for best growth and flowering. Fertilizer spikes can be helpful in providing nutrients but should not make up more than 25% of the total dosage rate, as this may harm your plant.
  • It is very important to keep your plant in an area where it receives bright, indirect light for best growth and flowering. However, they may not be able to tolerate direct sunlight all day long or a location with harsh shadows; make sure there’s plenty of shade when you place them outside.
  • Avoid overwatering the Hoya australis, as this can cause root rot. Make sure to water them when they are dry and not drip wet (the best way is with a spray bottle).
  • Place in an area that has good air circulation to prevent fungal growths on leaves. If placed near any heat source, the leaves may become dry and brown.
  • Maintain a temperature of between 15°C to 22°C (59°F to 72°F) for best growth and flowering; any less than this will slow its progress. However, if placed near heat sources or in direct sunlight it can be exposed to temperatures up to 29°C (84°F) for short periods of time without harm.
  • Use a clean cloth or sponge to wipe down the leaves and stems every few weeks so that they will stay cleaner, fresher, and more attractive over time. Alternatively, you can simply place them in an area with plenty of light which should help keep dust off.
