Hoya Australis Lisa Growth Facts

Quick-growing, gorgeous, and low-maintenance, this multi-colored plant is a favorite for many houseplant collectors. 

How Big Does a Hoya Australis Lisa Get?

Hoya Australis Lisa may grow up to 10 feet long. However, when grown indoors, this plant will rarely grow those proportions, seldom growing over 4 feet long. 

Hoya Australis Lisa Care

Hoya Lisa is an easy-to-care-for plant with few needs, making it perfect for beginners or those with little time to dedicate to houseplant care. 

Hoya Australis Lisa Soil

This Hoya likes to be grown in a growing medium that has a loose, quick-draining texture. Therefore, a commercial succulent or cactus mix will work well for this plant. Alternatively, you may create your own soil mix by combing 1 part of commercial high-quality potting soil with two parts perlite or sand and additional incorporations of peat moss. 

Hoya Australis Lisa Fertilizer

This Hoya will benefit from a monthly feeding from a balanced liquid houseplant fertilizer during the warm growing season of spring and summer. Ensure that you follow label instructions and do not overfertilize. Fertilizer should not be given during the winter when the plant is semi-dormant, as this may lead to issues. 

Hoya Australis Lisa Watering

Regarding the care of Hoya Australis Lisa, watering is probably one of the most important things to get right. As this plant is a semi-succulent, they retain water within its leaves and are semi drought tolerant. As such, this plant is very sensitive to being overwatered and having too much moisture in its soil. Therefore, you should water this Hoya only every few weeks or when about half of the moisture in the soil has dried out. In the winter, the watering frequency of this Hoya should be reduced even more. If you see the foliage of your Hoya yellowing, it is likely indicative that you are overwatering. 

Hoya Australis Lisa Light Requirements

Being a tropical plant, this Hoya likes to receive bright, indirect light throughout the day. Keep in mind that harsh, direct sunlight will cause leaf scorching to your plant. This plant will do well to be placed next to a southern or eastern-facing window. 

Hoya Australis Lisa Temperature & Humidity

Hoya Australis Lisa will thrive in average indoor temperatures, between 65 to 75 degrees Fahrenheit. You should keep in mind that this tropical plant should never be exposed to temperatures below 55 degrees Fahrenheit, as this may cause severe damage. Additionally, it is essential to note that this plant does not like large fluctuations in temperature and therefore should be kept away from air vents, AC units, heaters, and cold windows. While this plant will tolerate average indoor humidity levels, they appreciate having additional added air moisture, such as from a humidifier or pebble tray. You may also mist this plant to provide it with some extra humidity. 

Repotting Hoya Australis Lisa

It should be noted that this Hoya does not like to be repotted often, likes to remain a bit rootbound, and may experience a bit of a shock when disturbed during repotting. However, if the roots are seen poking through the drainage holes, repotting may be in order. Repotting will likely not need to be done more than every 2-3 years. Ensure that you select a container 1-2 inches larger in diameter and not significantly larger, as this may lead to issues such as root rot. 

Hoya Australis Lisa Maintenance & Pruning

Pruning of Hoya Australis Lisa should be done in spring during active growth. Old, diseased, or discolored foliage should be removed using clean shears near the base of the plant. Avoid being overly aggressive with pruning new foliage as this may stunt growth. However, long overgrown vines may be trimmed as needed. Suckers should be removed periodically. 

Hoya Australis Lisa Propagation

Propagation of the Hoya Lisa plant may be done through stem cuttings. Using a pair of sharp, clean shears, take a leaf cutting that is at least 4″ long, cutting as close to the main stem as possible. Place the cutting into water. A rooting hormone may be added to encourage rooting. After the cutting has roots that are a few inches long, they may be planted into fresh potting soil. After planting your cutting, water thoroughly and place in indirect light.
