"On time, reasonable cost, fast job with two people. Cut and disposed off our Queen Palm Tree, and trimmed the height of two hibiscus trees - cleaned the backyard after the job. All professionally done, but lost my original check given to them; asking for another one!"

"This company goes way beyond expectations. They trimmed all my trees and brushes around my house to look healthy. They removed 4 sets of bushes. They cleaned up everything. He noticed my sprinklers were not working and replaced the parts ( of course with my permission). All workers were polite and had a great work ethic. I wish I had more work for them. I am sharing their work with my friends to get them more business. They are reasonable in their charges. They are easy to communicate with. I would highly recommend them."

"I called HomeAdvisor looking for a tree trimmer. They responded within minutes and within an hour Robert was at the work site to evaluate the job abd managed to schedule a two-man crew for 0800 the next morning. They. were on time, worked in a safe and prifessional manner, and did a thorough clean-up. I was very impressed."

Arborists questions, answered by experts

As a general rule, the protected area should be about 1½ times as wide as the canopy of the tree’s leaves. This digging measurement can vary by tree species and the age of the tree. Of course, that can be a lot of fencing for larger trees, which is why our first step is about making difficult decisions on which trees to save.

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.

Your neighbor is not in a good position to know if your trees are truly dead or pose any kind of danger. That’s why hiring an arborist or tree service expert can be such an important part of the process. If the trees are still alive and don’t pose any threat, you’re in the clear (but you may want to document and photograph everything in case events turn sour down the road).

But if a tree is visibly dead and near the property line, you should remove it to be safe. If a dead tree falls on a neighbor’s property, they may have grounds to sue for negligence. If any branches on trees have died, it’s a good idea to cut them back for similar reasons.

You’ll have to balance up the cost, the value of the tree (sentimental or otherwise), and the risk factors. An experienced arborist will help you understand whether transplanting is likely to be successful. The cost and hassle of transplanting a large, well-established tree are often not worth it, especially if the species is fast-growing and easy to source. The decision depends on the age and species of the tree, the conditions in the new site location, and how careful the company is when digging out and moving the tree.

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.
