Cultivation and Propagation: Synadenium grantiiSN|23048]]SN|23048]] is very suited to growing on sunny terraces of warm areas need full sun to light shade with a very well drained soil mix with sand or perlite with small gravel added to ensure good drainage. Water them thoroughly and allow to dry before watering again. Fertilize the plants only once during the year with a balanced fertilizer.
Maintenance: The size of the plants is easily controlled by container size. The most important thing about growing these plants is be very careful not to over water them.
Propagation: Cutting and seed. The fresh cuts should be dipped in charcoal dust to stop the leaking of milky sap and should be struck in sand to root.

This one should not be grown around small children or animals that like to eat plants and be very careful to avoid the wounded surfaces when repotting or trimming up unwanted growth because of the corrosive milky sap.
Symptoms: Immediate or delayed irritation (burning, redness, blisters, swelling) to skin and eyes following contact with milky latex; ingestion causes irritation of lips, tongue, and throat.
Toxic Principle: Diterpene esters.
Severity: Hihly toxic, maybe fatal if eaten. Skin irritation severe.
