potting sizes

Question

can you tell me what size pot to use for a salix integra flamingo stem. the label says it will grow to 5ft tall and 5ft wide.

Answer 1

This depends on the size of pot that the plant is in now! You should only go up 1 or 2 sizes of pot, or you can cause root rot in the plant.
At maturity you will need a large container such as a half whiskey barrel or 30 gallon pot.
