Keep the soil of poinsettias slightly moist–not too wet and not too dry. Add water as soon as the surface of the soil feels powdery dry. Keep water off the leaves and bracts. Water (especially cold water) can leave ugly blackspots and cause plant diseases.
Use subirrigation (water from the base) to decrease how often you need to water the poinsettias. Each poinsettia needs a water-proof saucer or container. You can use the saucer as a subirrigation water source. You must protect poinsettias from the cold and from drafts. Poinsettias are tropical plants and like warm temperatures.
Each week, remove any dead and yellow leaves, bracts and flowers, this will keep your poinsettias looking fresh and healthy for a long time.
Q: Can I plant my poinsettia in the garden after Christmas is over?
A: Poinsettias are a tropical plant, so don’t fare well outside in Melbourne’s winter.
