Summarize the following:
By now, your branches may be too thick for pruning shears, so a fine-toothed saw ought to do the trick.  Cut as close to the base of the trunk or branch as possible. If you leave a stub, it may harbor pests and diseases. Consider pruning the small shoots at the ends of the branches as well. This will give you bigger, tastier pomegranates! This is something that you should be doing throughout your tree's lifespan. Suckers and water sprouts will appear the most in the summer, but if you see them at other times during the year, it wouldn't hurt to prune them off. Incoming suckers and sprouts will always be thin, regardless of the tree's age, so a pair of pruning shears will do the trick. You can allow the tree to grow taller, but it will be harder to harvest it. This is because most of the fruit grows on the top of the tree. You can easily reach the fruit on a 10 to 12 ft (3.0 to 3.7 m) tall tree with a 9 ft (2.7 m) tall ladder. Most pomegranate trees will reach about 10 to 12 feet (3.0 to 3.7 m), but some varieties may grow taller. In this case, trim the branches shorter. Your pomegranate will bear lots of fruit, but there may come a time when you have to pick-and-choose which branches to keep and which branches to prune.  Cut the branches as close to collar as possible. The collar is the raised ring between the trunk and the branch. If you keep all of the branches, you'll be preventing the healthy ones from getting as much energy as they could. If the tree is still very young, you only need to trim the first 4 to 6 inches (10 to 15 cm). If the tree is older, then it would be better to cut 12 to 24 inches (30 to 61 cm) instead. This will help expose the new wood, which will encourage more growth. Think ahead when pruning in the winter and use your best judgement. If a branch is long and close to the ground, give it a gentle pull. If it touches the ground, prune it shorter. If the fruit touches the ground, it may rot or get contaminated.
Remove dead, diseased, or crisscrossing branches in the winter. Prune away suckers and water sprouts in the summer. Keep the tree around 10 to 12 feet (3.0 to 3.7 m) tall. Prune away branches that don't bear good quality fruit. Trim the tips of the branches to encourage new growth. Make sure that the fruit does not weigh the branches to the ground.
