Complete Care Guide for Hoya kerrii:

Light

Position your Hoya kerrii in bright, indirect light for optimal growth. It thrives in spaces with consistent light levels of 500-800 foot-candles. While it tolerates low light, insufficient light can slow growth and prevent blooming. Avoid direct sunlight, which may scorch its delicate leaves.

Watering

Allow the soil to dry out completely between waterings. Hoya kerrii’s succulent leaves store water, making it drought-tolerant. Overwatering can lead to root rot; use a moisture meter if needed.

Humidity

Maintain humidity levels between 40% and 60%. In dry climates, use a humidifier to boost humidity. Avoid misting, as it can cause fungal issues.

Temperature

Hoya kerrii thrives in temperatures between 18°C and 26°C. Protect it from frost, drafts, and heating vents.

Soil

Use a well-draining soil mix, such as a blend of 50% potting soil, 20% sand, 20% clay granules, and 10% rock dust. Cactus or orchid soil mixes are also excellent choices.

Repotting

Repot every two to three years or when roots outgrow the pot. Terracotta pots with drainage holes are ideal to prevent overwatering and promote healthy roots.

Fertilizing

Feed monthly with a balanced liquid fertilizer to support growth and blooming. No seasonal changes in fertilizing are required.

Propagation

Propagate using stem cuttings with at least two nodes. Root them in water or a well-draining soil mix. Leaf cuttings can be decorative but may take years to grow into a full plant.

Semi- and Hydroponics

Hoya kerrii adapts well to semi-hydroponics. Use LECA (lightweight expanded clay aggregate) with a nutrient solution to maintain steady growth.

Pruning

Prune sparingly to maintain shape. Remove dead or damaged stems, but leave peduncles intact as they rebloom.

Placement

Position near an east- or west-facing window for bright, indirect light. During summer, it can be placed outdoors in shaded areas but must be shielded from direct sunlight.
