Hoya Tips
More than beautiful flowers
Hoyas come in many varieties, with distinctive leaf shapes, textures and colours. Their ornamental value lies in both their foliage and their clusters of fragrant, porcelain-like flowers.
Light encourages flowering
Also known as wax plants or porcelain flowers, Hoyas prefer warmth and plenty of bright, indirect light. Near a south-facing window, protect them from strong midday sun with a sheer curtain.
A little nectar is normal
During flowering, Hoyas may produce drops of sticky nectar. This is completely natural. Protect nearby furniture and gently wipe any surfaces if necessary.
Plant Care Hoya
Light
Provide bright, indirect light. A little gentle morning sun can be beneficial, but strong midday or afternoon sun may scorch the leaves. Hoyas tolerate lower light, although flowering is less likely.
Watering
Allow the upper third to half of the substrate to dry before watering again. Water thoroughly, let all excess water drain and never leave the pot standing in water. Overwatering can cause root rot. Reduce watering in winter.
Temperature
Most Hoyas thrive at 18–24°C. Protect them from cold draughts and sudden temperature changes; many species should be kept above approximately 12–15°C.
Pruning
Remove dry or damaged growth and shorten overly long vines when needed. Do not cut off old flower spurs (peduncles), as many Hoyas bloom again from the same points.
Feeding
During active growth, apply a balanced liquid houseplant fertilizer at reduced strength every 3–4 weeks. Reduce or stop feeding during winter.

Height & Growth Habit
Growth rate and mature size vary by species. Many Hoyas trail or climb and can reach several metres indoors, while compact varieties remain much smaller. A support or trellis helps climbing types develop neatly.
Pet Safety
Commonly grown Hoyas are generally regarded as non-toxic to cats and dogs. However, their milky sap may irritate sensitive skin, and chewing plant material may still cause stomach upset.
Origin
Tropical and subtropical Asia, Australia and the Pacific islands.
Substrate
Use a light, airy and fast-draining mix. Because many Hoyas are epiphytic, a chunky blend containing bark, perlite or pumice works well. Repot only when necessary and avoid moving the plant into an oversized pot.
