Q.Container Size
My hardy fuchsia is about 4 1/2 feet tall in a container. It’s about 4 years old. What size container should it be in?

If you are planning to repot the fuchsia, only go up one or two inches in width. Suddenly going up several sizes can cause overwatering of your plant and lead to stem or root rot. A visual cue is that the container should be about half the size of the plant. So the length of the container would be pleasing to the eye if it were about 2 feet tall.
