"They did a real good job. They were real professional. We can now open the garage door from the inside of the house and now it is so smooth that we have to check to see if we hit the button to open it or close it.  Before we used to know when it was opening or closing because it used to make a noise. It helps when you move to a city where you are new. "

Arborists questions, answered by experts

You should not trim an oak tree in the summer. Oak trees are especially susceptible to disease, and open tree wounds are an invitation for beetles that carry tree-killing fungus. If there’s no risk that the oak tree will do damage to your property or hurt someone, it’s best to save the trimming for fall or winter. If you can, seal the wound with latex to prevent fungus from getting inside.

An arborist specializes in tree care, performing tasks such as pruning, treating diseases, and removing hazardous trees. They also assess soil conditions, plant trees, and develop landscaping plans to ensure healthy growth. They also manage debris cleanup, inspect equipment, and record maintenance activities. Arborists often collaborate with landscapers and professional tree maintenance services, applying their specialized knowledge and problem-solving skills to maintain tree health and safety.

DIY is risky and not recommended for large trees; professional services ensure safe removal and proper disposal.

If you don’t cut down a dead, dying, or diseased tree, it can become a nesting place for pests like mosquitos, bees, beetles, wasps, fly larvae, and more. Some pests will live in the tree, while others will feed off the decaying wood. Unhealthy trees are also more likely to fall over, potentially injuring people and causing damage to your property.

Light-bark trees are most notorious for producing lots of sap when wounded. These varieties include maples, birches, poplars, dogwoods, magnolias, and elms, and they will bleed more when the trees are dormant. That’s why it’s a good idea to prune them in the summer months rather than waiting until winter.
