Water weekly in Spring and Summer, reduce to every 14 days in Winter.
Feed every 14 days from Spring to late Summer.

An East or West facing windowsill suits them well. The climbing species should be trained around wire hoops, up trellis or over tripods of canes.
Hoya bella should not be placed on polished furniture because the flowers produce sticky nectar which can fall in droplets and causing damage.

Spray twice weekly with tepid water, except when the flowers are open.
Most plant cells look like little boxes full of green disks. The disks are called chloroplasts. Other organelles inside a plant cell include a nucleus (where the DNA is kept), a large central vacuole (where water and other materials are stored) and a complex internal skeleton or cytoskeleton made of various proteins.
