Article: While pomegranates are more of a shrub than tree if left to grow untrained, you can trim the plant so that it looks like a tree. This is something that many gardeners do.   Using gardening shears or clippers, cut the suckers (the smaller branches that help the plant take on its shrub form) growing at the base of the plant so that it takes on more of a tree shape. Do this shortly after the plant has become established. If you don't care whether your plant is tree-like or not, let it grow naturally. You don't really need to prune your pomegranate tree to maintain it, but it is a good idea to cut away dead or dying branches in the spring to help the tree grow well. You can also thin the plant as you see necessary. If you are growing the pom in a container, you will need to prune and train a bit more heavily, in order to keep the pom the size and shape you want it to be. Avoid mold growth by making sure you do not over water the pom. The two other problems some pomegranates face are aphids and the pomegranate butterfly. You can kill aphids by using a spray bought at your local nursery or garden store. You can also use an integrated pest management practice for killing aphids, which may include attracting ladybugs, spraying trees with water to knock aphids down, or even purchasing predatory insects to consume the aphids. The pomegranate butterfly is not very common and should not be a problem. If it is, use a butterfly spray to rid your trees of the larvae.

What is a summary?
Train the plant into tree form, if desired. Remove dead or damaged parts of the plant. Keep the pom healthy.
