"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."

Customers say: True professional

"⭐️⭐️⭐️⭐️⭐️ I found this company online and was immediately impressed with the service provided by the owner, Chris. He responded promptly with a more than reasonable estimate for cleaning up my yard, which was in dire need of attention due to the recent record-breaking winds and rains in Simi Valley. My yard was cluttered with debris, broken tree limbs, and dead trees accumulated over the past six years. Chris and his crew worked diligently and completed the entire cleanup in just one day! Chris has a firefighter background expertise 🪓 They worked hard and didn't leave until I was completely satisfied with the results. I highly recommend Chris's business for any yard cleanup and tree trimming, stump removal needs and would definitely hire them again in the future! Thank you Chris and your crew keep up the good work ⭐️⭐️⭐️⭐️⭐️"

"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."

"Went great. They showed up on time and did a fantastic job. They covered the pool filter with plywood to avoid any damage from falling palm parts. The carrotwood tree belonged to the neighbor but extended into my yard too. They trimmed that nicely on both sides. They also trimmed the Bougainvillea's back to separate the neighbors tree from my side. Cleaned up nicely afterward too. (No dirt or anything in the pool! or the street). Highly recommended. Will use again."

Arborists FAQs, answered by experts

Aside from removing dead or diseased branches, you should prune your trees somewhere between every one and three years. Some people—particularly commercial farmers—prune their apple trees yearly to produce higher yields. This is the best way to promote tree health. That said, the average homeowner can get away with hard-pruning their mature apple tree every other year or every three years. 

It takes anywhere from three to seven years for a stump to decompose on its own. This timeframe can depend on the kind of tree and your climate. The lower to the ground the stump is, the faster it rots. If you kill a tree stump with salt, boiling water, herbicide, light deprivation, or burning, the tree stump decomposes faster. 

For trimming trees, your best tool is a pair of pruning shears or loppers. Both options work best for branches that are under 3 inches in diameter. Trimming trees with a larger diameter may require a robust tool like a small chainsaw or a handsaw, so take into account your tree’s diameter when deciding between tools.

Yes, many services include stump grinding to eliminate tripping hazards and improve aesthetics.

The best time to trim trees is in late fall through winter when the tree has slowed its growing for the year. Cold weather stops insects and fungal growth from attacking a new tree wound. Summer and fall are considered the worst times to trim trees, but it’s permissible in certain scenarios, such as tree disease, damaged branches, or small, aesthetic cuts.
