"High marks for following through and meeting their commitment and doing great work. I had an Almstead arborist review the property and provide recommendations on some dead limbs and trees. We came to an agreement. When the crew came, the arborist wasn't there (later found out she'd left and moved north). As far as I could tell, the crew didn't have the instructions we'd agreed on and they did some, not all of the work. What followed was back and forth, but after a few months they sent out the crew to remedy the missing work. They did a great job and I was very glad. I appreciate the office staying on it and making it right. I've used them for 24 years and happily look forward to continuing to use them. It's a lot to trust your trees to someone!"

"Very pleased with Almstead's service including speaking with Kristen, Michael's tree inspections and pruning crew. The 3 crew members were polite, very efficient, and did a great job of "cleaning up". Also impressed with Almstead's equipment and technology."

Arborists FAQs, answered by experts

Professionals use assessments, strategic cuts, specialized equipment, and safety measures to ensure healthy growth or the safe removal of trees or shrubs.

The best time to transplant a tree is when it is dormant. For many trees, this means either in the fall after the leaves have dropped (around October or November) or in early spring before new growth begins (around March). The ideal timing can depend on the type of tree. Deciduous trees do well when moved in early spring or fall, while evergreens are best transplanted in early spring or late summer. For example, pine trees are best moved in early fall, but maples prefer late fall. Avoid transplanting in winter, as the frozen or hard, cold soil poses a significant risk to the roots and prevents the tree from acclimating properly.

Stay inside or well away until the storm passes. Don’t go outside to inspect the tree until the weather clears, especially if the tree is on a hill or isolated in a field. Lightning often strikes the same easily-accessed places multiple times, and you could be a new target. If a lightning strike causes a noticeable fire, alert emergency services. When the storm is over, take a closer look to gauge the damage done.

If the roots are still alive, the dead tree will usually try to put out new shoots. That doesn’t mean the tree will survive or that the dead parts of a tree will come back to life. If parts of the tree have died and turned gray or rotten, nothing will bring them back to life and they need to be safely removed.

To maintain trees on a commercial property, perform regular pruning, monitor for diseases, and apply fertilization to promote healthy growth. It is also important to remove any hazardous branches to keep the trees healthy and prevent potential liability issues.
