Hoya Australia

Hoya australis shares enough qualities with Orchids that many gardeners use Orchid fertilizers on this species of Hoya. Make sure to use a well-aerated mix with good drainage in order to avoid suffocation and waterlogging. Something too dense, like garden soil, will choke out the roots and retain an excessive amount of water. A poorly-drained and boggy soil will cause fungal root rot. If your Hoya australis is greatly damaged by root rot, the only way to save your plant is to take cuttings immediately.

But it can do just fine in 40–60% humidity, the low end of which is about the average household humidity. Hoya Australis enjoys the sunshine year round in Australia, so its ideal temperature range is between 65 and 75 degrees Fahrenheit. Any extremes below or above that range will stunt its growth and may even kill it.

Hoya Australis Flowering

It easily allures wildlife like hummingbirds, butterflies, and bees. The Hoya australis is equally happy trailing from a basket or climbing support. This plant’s slender vines can reach 13 feet around 33 feet long. Put the pot in indirect sunlight and keep carefully the cutting warm. A well-draining mixture will certainly reduce overwatering damage and protect the plant from root-rot. The pH of the potting mixture should be ranging from 6.1 to 7.5, i.e., mildly acidic to neutral.

• You may also apply an excellent quality commercial plant nutrition treatment for boost growth for the Hoya australis.
• Each smooth, exquisite flower looks to be built from wax or sugar icing.
• Whiteflies mostly grow on the undersides of the leaves.
• You can increase the indoor humidity level in the greenhouse by keeping a water tank.
• Remove the leaves at the base of the cutting, use root hormone if desired, insert into moist starter mix .
• Hoya australis has medium to low water requirements and can take short droughts lacking any issue.

I prefer to use equal parts peat/coco coir, orchid bark, and perlite. I often add 10% worm castings to improve soil fertility. One sweet spot for light indoors is two to four feet in front of a sunny window. Hoya australis is on the light-loving side of the Hoya spectrum. In northern climes, the plant can reap the benefits of even more direct sun. Hoya australis is a wonderfully hardy, climbing, twining vine with plenty of personality. They grow at
Repotting Hoya australis shouldn’t frequently occur, no sooner than once every two years. Only consider repotting if the roots are visible above the soil.

Growth Zone

As for lowlight conditions, Hoya Australis will tolerate them, but they won’t bloom nicely and can grow slower. Hoya Australis care is easy, much like other styles of hoya plants.

Temperature and light have an outsized role in stimulating blooming. Should you choose find an infestation, repeated treatment utilizing a light horticultural oil or insecticidal soap usually brings it in order. Some growers prefer spraying the bugs with a dilution of 9 parts water to 1 part isopropyl alcohol. Test discretely on a leaf and wait a couple of days to ensure it doesn’t discolor or show other damage. Sometimes Hoyas released misshapen or “highly individualized” leaves.

I am going to move my hoyas outside once the nights stop dipping below 60 degrees Fahrenheit. In the winter, it’ll do fine with being watered only 2 times or so per month. Move your wax plants to a bright window to expose them to more daylight. With a bit more sun exposure, it can help your Hoya australis develop those gorgeous star-shaped blooms. The simplest way to expand your Hoya australis collection is through stem cutting propagation. Doing this provides enough drainage to avoid overwatering your plant.
The plant requires different watering schedules for different times of the year. Hoya australis has medium to low water requirements and will take short droughts lacking any issue. Being an epiphyte, it prefers having well-oxygenated roots.
