Everything it needs
9 essentials at a glance
Watering
Hoya linearis prefers to dry out slightly between waterings.
Water every 1-2 weeks during the growing season (spring and summer), allowing the top 1-2 inches of soil to dry out. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaves to shrivel and drop.
Light
This plant thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, it should receive 6-8 hours of light daily. Avoid placing it in low-light conditions, as this can hinder growth and flowering.
Soil
Hoya linearis prefers a well-draining potting mix, ideally a blend of peat, perlite, and orchid bark.
A pH range of 6.0 to 7.0 is optimal. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
Hoya linearis enjoys high humidity levels of 50-70%.
To increase humidity, consider using a pebble tray with water or a humidifier. Signs of low humidity stress include browning leaf edges and stunted growth.
Temperature
The ideal temperature range for Hoya linearis is between 65-80°F (18-27°C).
It is hardy in USDA zones 10-12. Protect it from temperatures below 50°F (10°C) and avoid cold drafts.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 every 4-6 weeks during the growing season.
In fall and winter, reduce feeding to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune Hoya linearis after flowering to maintain its shape and encourage bushier growth.
Use clean, sharp scissors to remove leggy stems and spent flowers. Deadheading spent blooms can promote new growth.
Repotting
Repot Hoya linearis every 2-3 years or when it becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Gently remove the plant from its pot, loosen the roots, and place it in fresh potting mix.
Propagation
Hoya linearis can be propagated through stem cuttings.
Take 4-6 inch cuttings with at least two leaves and place them in water or moist potting mix. Ensure the cut ends are treated with rooting hormone for best results. Propagation is best done in spring or early summer.
When it's unhappy
Yellow leaves
Why it happens
Over-watering or poor drainage.
How to fix it
Ensure the pot has adequate drainage and allow the soil to dry out between waterings.
Shriveling leaves
Why it happens
Under-watering or low humidity.
How to fix it
Increase watering frequency and humidity levels to prevent leaf shriveling.
Leaf drop
Why it happens
Sudden temperature changes or stress from repotting.
How to fix it
Maintain stable temperatures and avoid moving the plant immediately after repotting.
Pests (e.g., mealybugs, spider mites)
Why it happens
High humidity and poor air circulation.
How to fix it
Regularly inspect the plant, and treat infestations with insecticidal soap or neem oil.
Poor flowering
Why it happens
Insufficient light or nutrients.
How to fix it
Ensure the plant receives bright, indirect light and fertilize during the growing season.
Care through the year
Spring
In spring, resume regular watering and fertilizing as the plant begins its active growth phase. Prune any leggy growth after flowering.
Summer
During summer, ensure the plant receives bright, indirect light and maintain humidity levels. Water more frequently as the plant actively grows.
Fall
In fall, gradually reduce watering and fertilizing as the plant enters dormancy. Monitor for pests as indoor conditions may change.
Winter
In winter, water less frequently and keep the plant in a warm area, away from drafts. Consider using a grow light if natural light is insufficient.
Toxicity & Safety
Hoya linearis is considered non-toxic to pets and children. However, ingestion of large quantities may cause mild stomach upset. Always monitor pets around houseplants.
