"I needed invasive vines and poison ivy removed from areas around my property.Matt went over the whole job with me and explained the way he would do it and assured me about the safety of his method. He even noticed something that needed to be be treated on a magnolia in my yard. He arrived the next day and did the job quickly and thoroughly. Hi price was more than fair. The fact that he was a licensed arborist and had other certifications was doubly ressuring."

"They are incredible! Julio is a perfectionist, him and his team are second to none! Besides all of them being completely professional and real gentleman's! They do my lawn, my gardens and mulching, tree work, trimming hedges, and beautiful masonry. I will never not use them unless I want to do something, but once you get spoiled using them you stop doing work yourself! Great company!"

Arborists questions, answered by experts

Generally speaking, you’ll want to avoid flush cuts, which are cuts made as extremely close to the trunk or main branch. These cuts can weaken your tree, lower its natural defense mechanisms, and even cause decay. You’ll also want to avoid tree topping, which is the total removal of the leader and upper main branches of a tree. 

Most pros will advise against either of these methods, which is why hiring a pro is often the best choice when it comes to tree trimming.

Most plum trees are pruned into a vase or open wine glass shape. They’ll have a shorter central leader (the trunk) that supports three to four main branches. Of course, this isn't always the case. If you have a European plum tree, you can grow it in a pyramid shape. Let the central leader extend the length of the tree and prune smaller branches to create the pyramid.

While palm trees can bring aesthetic appeal to your yard, they have a couple of drawbacks. The main disadvantage is that many types require warm climates, so if you live in a cold region, you need to ensure you pick a palm that can withstand the freezing temperatures. Another downside is that maintenance can be difficult because of their height, which means you will need to pay a pro to prune the tree as needed.

Yes, it’s okay to trim low branches on a tree, also known as limbing up or raising the crown. Essentially, you’ll trim the lower third of the tree (trunk) and leave the upper two-thirds of the tree (crown). Arborists recommend trimming 20% of a tree’s leaves per season for two to three seasons. Trimming low branches allows light to flow through the tree, increasing circulation and making the tree stronger and healthier.

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.
