"Mike and his crew are true professionals. I would hire again without any hesitation. They removed 50' of tall hedges and 5 evergreen trees. They completed the removal and cleanup in under 2.5 hours. They were very careful not to damage other vegetation or personal property of our house and our neighbors. And dug out 2 trees by hand because they wanted to make sure that no electrical or water lines were damaged. I wish all the pros we hire were as skilled and professional as this crew."

"Excellent Tree Removal Service by LA Arbor Care In March 2023, our plumbers told us that our sewer pipe ran right under our large Deodar multi trunk pine tree, and that the treeâ  s massive roots had detrimentally damaged the sewer pipe leaving us with no other option other than to remove the tree and grind the stump so they could dig a hole under it to repair the pipe. We received four estimates from different tree removal companies. Miguel Lopez at LA Arbor Care did not provide the least expensive estimate, but we felt that his considerable experience, certifications, and great reviews made his firm our best option. We are so pleased that we selected LA Arbor Care to do this work. They did the work exactly as promised, removing the tree safely and efficiently. We were impressed by their work ethic and quality, and they were very careful not to damage the power and data lines that were coming through the tree branches. They were conscientious about leaving the entire work site impeccably clean â  for example, the tree was adjacent to our swimming pool, and unprompted, they cleaned all the leaves and branches that had fallen into the pool during their process of taking down the tree. Miguel and his staff were friendly and professional. I would highly recommend them to anyone who needs tree removal services."

"INCREDIBLE! This was the first time that my trees have be pruned and shaped correctly in over 40 years. I am so happy with the work. One tree was next to my pond; the crew put a large tarp over the pond so no debris fell into it, so I didn't have any pond clean up work to do. My yard was left in better shape than when the crew got here. I am planning on asking them to come back in the spring to get my winter garden in shape for the growing season."

"I had a landscaping design/build company until illness kept me from continuing. I felt like I was in good and knowledgeable hands when Rock came out for the estimate - he is an arborist so he understood exactly what I wanted. His crew showed up on time and were very professional with a very capable foreman who interpreted Rock's job description accurately, so the job was done perfectly and the place was clean afterwards."

Arborists FAQs, answered by experts

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.

Deciduous shade trees (the type of trees whose leaves fall off in autumn) need to be pruned in late winter—between February and March. That’s because it’s easier to find and remove sick or dead branches when no leaves are present. And wounds close and heal faster in colder temperatures so pruning them at this time also makes them less prone to infection.

Steer clear of the area and contact your utility company immediately. It will have a website portal and/or a phone number to report downed trees and electrical issues. If the tree appears to be on public land, you may want to call your local government and report the issue there, too.

Not all evergreen conifers need to be pruned, but some do. Pruning pine trees is not necessary, but you can do so during June and July if you wish. On the other hand, spruce, firs, and junipers do need to be pruned from late winter to early spring.

Homeowners are usually not responsible for trees that fall on power lines. Power companies usually have utility easements around power lines, which give them the responsibility to maintain any trees within about 15 to 20 feet of the lines.
