Late winter is ideal, but if you’re pruning apple trees in the spring, prune them as early as possible in the season. You want to ensure your tree is just creeping out of dormancy and hasn’t started pushing out new growth. If you prune your tree too late into spring, you generally won’t see results until the following year.

That said, there’s no pruning season for unhealthy growth. Remove dead, dying, or diseased branches as soon as you notice them, regardless of the time of year.

Full decorating services often provide rental trees for their Christmas packages, so you shouldn’t have any trouble finding one. However, individual interior decorators and others may not offer rented trees, so always check the specifics of their services before booking. Keep in mind that you’ll need to prepare the Christmas tree for pick-up shortly after the holidays.

Whether tree roots will continue to grow after a tree has been cut down depends on the species. Some tree roots will eventually die because they can no longer get nutrients through photosynthesis. However, other species that reproduce through root sprouts can continue to grow and produce new sprouts for seven years or more. For example, the roots of elms, ficus, and willows tend to regrow aggressively, while the roots of pines, oaks, and maples will typically die. To determine if a root system is still active, look for new sprouts on the old trunk, stump, or any exposed roots.

Any tree that needs to be pruned should be pruned to remove dead branches at least once a year. You may need to prune far more often if you’re trying to maintain a certain shape or to save a tree that suddenly becomes infected.
