Water
Allow the top 2-3 cm of soil to dry out completely between waterings. Hoyas prefer to be on the drier side, so avoid overwatering, which can lead to root rot.
Reduce watering frequency during cooler, less active growth periods.

Watering, pruning, propagation, and repotting details from plant data
Allow the top 2-3 cm of soil to dry out completely between waterings. Hoyas prefer to be on the drier side, so avoid overwatering, which can lead to root rot.
Reduce watering frequency during cooler, less active growth periods.
Prune to maintain shape, remove dead or leggy growth, or encourage bushier development. Pruning can be done anytime, but it's best to do it after flowering has finished.
Avoid cutting off the spurs from which flowers emerge.
Easily propagated from stem cuttings. Take cuttings of 10-15 cm with at least two leaf nodes. Remove the lower leaves and plant the cut end in moist potting mix or water.
Roots will form in a few weeks, especially in warm conditions.
Repot every 2-3 years, or when the plant becomes root-bound. Use a well-draining potting mix, such as an orchid or cactus blend, with added perlite.
Choose a pot only slightly larger than the current one to avoid excess moisture retention.
