"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

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.

The speed of your tree root removal process depends on a few different factors, including the size and type of tree. However, the fastest method of killing tree roots is applying chemical herbicide, which starts working quickly and efficiently. But this removal method has its drawbacks, such as having a negative effect on the surrounding vegetation and landscaping. Other options like rock salt and stump grinding work relatively quickly and cause less damage to your yard.

You can use herbicides to prevent roots from growing without killing the tree itself, however they must be used with caution. Systemic herbicides are absorbed by the root and can kill off problematic roots. However, herbicides can sometimes negatively impact nearby plants, so the solution is best used sparingly.

In most cases, leaving tree roots underground is not a problem if the stump has been removed or ground below the soil. However, some larger roots may decompose, leaving dents in your soil. Additionally, some aggressive trees, including willows, oaks, elms, maples, and poplars may grow back from roots. Large aggressive trees with established root systems are more likely to grow back.

If a tree isn’t pruned, it can inhibit proper growth and fruit production, cause damage to both the tree and your property, and create entry points for pests and diseases. Pruning a tree enhances its stability, appearance, shape, and growth. Pruning trees regularly can also save you money long-term by avoiding overgrown or dangerous dying trees.
