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.

In most cases, you should not use a pruning seal on trees after trimming. Applying a sealant can interfere with the tree's natural healing process, and it does not guarantee protection from pathogens. Instead of sealing the cut, the best practice is to support the tree's natural recovery by providing it with plenty of water and a dormant-style fertilizer. However, there are exceptions. Pruning seals may be recommended for very vulnerable species, like elm trees, in areas where dangerous diseases such as Dutch elm disease are prevalent. In these specific situations, the protection offered by a sealant can outweigh its downsides. For advice tailored to your situation, especially after cutting large branches, it is best to consult a local tree trimming professional.

If a tree isn’t pruned, it can inhibit proper growth and fruit production, cause damage to both the tree and your property, and create entry points for pests and diseases. Pruning a tree enhances its stability, appearance, shape, and growth. Pruning trees regularly can also save you money long-term by avoiding overgrown or dangerous dying trees.

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.
