The tropical trees and shrubs are a diverse group of plants. Most of these plants have the potential to get quite large and will require regular pruning and repotting with root pruning to stay a manageable size. The trees should be able to fit through doorways and be under ceiling height for the labs. The best time to prune these plants is in the early winter after they are no longer needed for courses and they will flush out come spring and be ready for summer courses.
