"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."

"Joel and his team did an excellent job on our spring cleanup and mulching. They were very hard working and paid great attention to detail. Everything turned out better than expected. They have also began to mow our lawn weekly and have been great. The pricing is very reasonable and I highly recommend to anyone in the area."

Arborists questions, answered by experts

When a palm tree no longer produces new fronds and old fronds start turning yellow-brown, that’s a sign the tree is dying. However, transplanted palm trees can show these signs for the first several months as they re-establish themselves. It’s best to keep watering and not give up on the palm tree until a couple of seasons have passed and you’re sure it’s not coming back to life.

There are four common ways to prune a tree correctly: crown thinning, crown reduction, crown raising, and crown cleaning. The method you choose depends on the purpose of pruning. However, making the correct cuts is a vital part of the process, regardless of your method. Pruning incorrectly can damage or even kill the tree. So, you may want to hire a professional tree-trimming company to tackle the task. 

No, you cannot throw branches from your neighbor’s tree back into their yard, nor can you discard leaves or other plant matter that originated from their yard back over there if it happens to land in your yard. You are responsible for cleaning up plant matter that made its way into your yard.

Before you cut down a dead palm tree, try to revive it using the methods listed above. However, there are instances when it makes sense to remove a dead palm tree, including:

  • The heavily infected tree will infect nearby trees, bushes, and plants.

  • The palm’s roots are overtaking your yard, foundation, and sidewalk and causing structural damage.

  • The tree is unstable and a hazard to your property, your neighbor’s property, and pedestrians.

Poison oak is similar to poison ivy in that it's in the same family of plants. Poison oak is identifiable by its rounded-off leaves and hairy leaf texture. Tree-climbing varieties live primarily in western states while low-growing poison oak bushes occupy the eastern states. Treat poison oak like poison ivy to get rid of it permanently.
