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.

Licensing requirements for arborists, also known as tree surgeons, vary by state and municipality. Many areas require a license, which often involves specialized education and experience. Even if not mandated, it's wise to hire a licensed professional as they tend to have more experience. Beyond licensing, look for certifications from organizations like the International Society of Arboriculture (ISA) or the Tree Care Industry Association (TCIA), as this indicates a higher level of expertise. Certified arborists must typically pass a comprehensive exam. Always confirm that the arborist has a business license and is fully insured to protect yourself from liability. Seeking positive recommendations from local homeowners is also a good step in finding a qualified professional.

A grafted tree is a tree grown by combining two trees. It takes expertise. Branches from grafted trees don’t grow strong roots. Save yourself the time and frustration by having an arborist help you with this advanced project.  

You can often tell if a tree is grafted because it will have a noticeable line. Above the line, the bark will look different than it does below the line. It’s most common with fruit trees.

Some fast-acting products can rot a tree stump in four to six weeks. Keep in mind, these products contain harsh chemicals that may prevent regrowth in the area. Other products, like fertilizer that contains lots of nitrogen, can enhance the process and rot a stump in about a year. (This is compared to the ten years it can take naturally for a stump to rot.)
