Below is a general care guide for Dieffenbachias which can slightly differ depending on variety.
Light & Temperature
Dieffenbachias or Dumb Canes are popular indoor plants because they do well in shady conditions. They prefer dappled shade or indirect light. The plant will grow more on the side of the light source so regularly rotating the plant will keep its growth even and balanced.
This plant loves fairly warm conditions and will lose its lower leaves when exposed to cold drafts.
Watering, Humidity & Misting
Dieffenbachias love regular moisture and do not like to completely dry out. About once a week of watering for small to medium dieffenbachias will keep its soil damp. Make sure the top 1-2 inches of the soil is fully dried out before watering again.
Soil and Repotting
Use a fast-draining, well-aerated potting mix. Make sure drainage is good to avoid root rot.
Repot the Dieffenbachia annually for healthy results. Wear gloves when repotting to avoid contact with its sap.
Propagation
Propagating a Dieffenbachia can be done by dividing offsets and planting them in their own pots. You can also cut off to the top and pot it or cut pieces of the cane and lay them horizontally on a potting mix and wait for the pieces to root.
Fertiliser
Use a balanced fertiliser formulated for houseplants. Follow the directions on the label of our Down to Earth. organic plant food.
