"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.

You can never truly stop a maple tree from growing taller, but you can rein in its growth by pruning. Proper pruning helps maintain a safe size for your tree without causing permanent damage. It’s important to start pruning a tree while it’s young, long before it becomes a problem. Otherwise, you may be left with too many hazardous branches to remove at once.

The best pro to hire for spraying trees is a tree maintenance specialist. These pros are well-versed in selecting the right spray treatment and applying it properly to ensure there’s no collateral damage to the tree or surrounding landscape. Many tree maintenance services employ certified arborists, but for these routine visits, the extra investment usually isn’t necessary.

Many consider the Fraser fir to be the most popular type of Christmas tree, but which type of tree sells out near you can depend on region and decorating trends that year. For example, the Leyland cypress is especially popular in the Southeast, according to the National Christmas Tree Association.

Salt, herbicide, light deprivation, boiling water, and burning can all help dissolve a tree stump. You can also bury the tree stump in soil or mulch to help it rot naturally. Killing a tree stump prevents future regrowth, but you may also remove it by digging it out or grinding it.
