These are very easy and forgiving to work with. Depending on if you want them to remain smaller, or grow larger you will either cut the bottom 1/3 of the root ball before transplanting, or leave them for a larger plant. They will fill out the size container that you put them in. They will stay in a very small container for a very long time, though.
