"Sixto’s crew showed up on time and got right to work taking down my 30 yr old jacaranda tree. They did a superb job being careful not to damage surrounding plants, grass or sprinklers. They cleaned up so well that you’d never know a tree was there! Great job!"

"Robert Duran and his crew from 3-D Tree Services, Inc. were top notch today from the quote/survey to completion! I am amazed how quick, efficient, professional and kind this entire team is to work with! This was a tough job (Old/Invasive Pepper Tree). The crew was in sync with each other, allowing the process to be quick and safe. I’m so happy I found them through Home Advisor and the response to my inquiry was quick. Thank you everyone! Referrals will flow!"

Customers say: True professional

"Excellent experience. I had to have two huge eucalyptus removed. Gilbert's bid was fair and that he's thoroughly insured was most reassuring. But what sealed the deal was not feeling I had to hire an arborist diagnose the problem because Gilbert is so knowledge. He not only told me the reason the trees had to be removed but was able to show me the proof. The crew was efficient, hard working and impressive. I also felt I was working with a very honest person. Happy to recommend Gilbert's Green Essence."

"I'm looking for more quotes just to see who can handle the jobs I have, but Pedro called me very quickly after I had set-up a HomeAdvisor. He was very prompt and respectful over the phone and spoke with me in an extremely professional manner. I would definitely recommend Castaneda's Tree Trimming service to anyone looking for Tree Removal or other arborist services."

Arborists questions, answered by experts

Generally, you do not have the right to take fruit from a neighbor's tree, even if the branches overhang your property. The fruit is considered the property of the tree's owner. While you may have the right to trim branches that cross into your yard, the fruit on them typically still belongs to your neighbor. However, laws can vary by state and municipality. In some areas, branches that extend into your yard or trees that straddle a property line may entitle you to some of the fruit. The best course of action is to speak with your neighbor, as they may be happy to share. If a conversation is not possible, check your local regulations before picking any fruit.

A dead tree should always be cut down, because it could fall and cause injuries or damage, and it can also attract insects like carpenter ants. A tree that’s diseased beyond repair should also be cut down, but it’s not always easy for a homeowner to tell. Signs of disease include dying branches, a hollow trunk, leaning, and discolored or missing leaves, but your best bet is to hire a local arborist who can evaluate the tree and tell you if it can be saved or should be cut down.

No. Most of the time, suckers are only a sign that the tree is experiencing stress. However, they can also be the canary in the coal mine, letting you know that something else is stressing your tree. If you have lots of suckers on your tree, calling in an arborist or a tree care expert is always a good call to determine the cause and develop a solution that de-stresses your tree.

You can shape a cherry tree by trimming vertical branches, dense branches, and intersecting branches. Your personal aesthetic comes into play, as well. If you want to simply thin and shape the tree, you can get away with trimming the aforementioned parts of your cherry tree. If you want to shorten branches, however, consider thinning cuts, which alter the length of the branches while encouraging light penetration, new buds and shoots, and a structurally-sound shape.

Large, established tree branches won’t grow roots, but if you find a young tree branch that’s less than about a year old, you’ve got a shot. Put it in water or soil as soon as possible for best results. You’ll know the branch is viable if it’s about the thickness of a pencil and has some leaves or needles.
