Care Guide for Hoya australis 'Lisa':


Light Requirements:
This Hoya thrives in bright, indirect light. While it can tolerate lower light, its variegation is more vibrant with lots of light. Avoid direct sunlight, as it can scorch the leaves.

Watering Needs:
Let the soil dry out between waterings. Depending on conditions, this can take a few days to a week, so check the soil regularly. Overwatering can lead to root rot, so ensure the pot has good drainage.

Humidity Preferences:
Normal indoor humidity is sufficient, but higher humidity (around 60%) is ideal. Use a humidifier or mist the plant occasionally, especially during winter.

Soil Requirements:
A well-draining, airy potting mix is key. A mix of orchid bark, perlite, and potting soil works well. Alternatively, a cactus or succulent mix with added perlite ensures proper airflow.

Temperature Range:
This plant prefers temperatures between 18-26 °C. Avoid temperatures below 10 °C. In winter, keep the plant away from cold drafts.

Repotting & Pot Choice:
Repot every two to three years, ideally in spring. Choose a pot with good drainage, like terracotta, which allows moisture to escape and prevents waterlogging.

Fertilizing Routine:
Feed once a month during the growing season with a balanced liquid fertilizer at half strength. During blooming, switch to a bloom-boosting fertilizer. Avoid over-fertilizing to prevent salt buildup.

Pruning Tips:
Trim long stems in spring or summer to encourage new growth. Avoid cutting more than one-third of the plant. Pruning helps with branching and produces more flowers. Use clean, sharp scissors to prevent infections.

Hydroponic Growth:
Hoya thrives in a hydroponic setup with a light nutrient solution. Change the water regularly and monitor nutrients.

Propagation by Cuttings:
Take cuttings in spring, about 10 cm long, with at least three to four leaves. Place the cuttings in a mix of potting soil and sand or in water until roots form—usually in 6-8 weeks. High humidity speeds up rooting.
 
 

Common Issues & Solutions for Hoya australis 'Lisa':

Pests:
Mealybugs, spider mites, and scale insects can be an issue. Inspect regularly and treat infestations with neem oil or insecticide. Prevent infestations by wiping leaves or using insecticidal soap.

Yellow Leaves:
Yellow leaves often indicate overwatering. Let the soil dry out before watering again, and ensure proper drainage.

Root Rot:
Root rot is usually caused by overwatering. Repot in fresh, well-draining soil and reduce watering frequency.

Leaf Discoloration & Drop:
Discoloration can be due to insufficient light or nutrient deficiency. Ensure the plant gets enough light and fertilize regularly—but don’t overdo it.

Temperature Fluctuations:
Keep the plant away from drafts or sudden temperature changes. A stable environment is key.
