The best time to trim trees is in late fall through winter when the tree has slowed its growing for the year. Cold weather stops insects and fungal growth from attacking a new tree wound. Summer and fall are considered the worst times to trim trees, but it’s permissible in certain scenarios, such as tree disease, damaged branches, or small, aesthetic cuts.

Pruning trees is important for several reasons. It improves tree health and strength by removing dead, diseased, or unwanted branches, which in turn encourages new growth and can help treat disease. For fruit trees, proper pruning can lead to a larger and better-quality harvest. Pruning also enhances safety by removing weak limbs that could break and fall, potentially causing injury or property damage, especially during storms. Beyond these functional benefits, pruning can also improve a tree's appearance. To ensure pruning is done correctly for the tree's long-term health, consider hiring a professional.

While palm trees can bring aesthetic appeal to your yard, they have a couple of drawbacks. The main disadvantage is that many types require warm climates, so if you live in a cold region, you need to ensure you pick a palm that can withstand the freezing temperatures. Another downside is that maintenance can be difficult because of their height, which means you will need to pay a pro to prune the tree as needed.

It depends. Smaller, younger trees take longer to mature, but they're more resilient, their roots don't get as damaged during transplanting, and they recover faster. Plus, they're much more affordable to plant, and it's possible to DIY the planting. 

On the other hand, mature trees produce fruit faster and provide more shade and privacy immediately. Ideally, a small or medium tree is the better choice if you can wait a few years for it to mature. But if you need immediate maturity, a larger tree is the only option.
