"We had a very large elm tree die this past winter. I got quotes from four reputable companies, and Hellmann's responded first and was the lowest, with the others 5 - 23 % higher. I selected Hellmann's on May 6, and they took down the tree on May 15 as scheduled. I was very impressed by how efficiently Ray and his crew worked. They were extremely safety conscious and careful to not damage an adjacent tree and the deck that they were working beside. All four men were always busy, and they did an amazing job of cleaning up the entire work area. I highly recommend them."

Arborists FAQs, answered by experts

A grafted tree is a tree grown by combining two trees. It takes expertise. Branches from grafted trees don’t grow strong roots. Save yourself the time and frustration by having an arborist help you with this advanced project.  

You can often tell if a tree is grafted because it will have a noticeable line. Above the line, the bark will look different than it does below the line. It’s most common with fruit trees.

A tree branch should start to form roots in about three months. It can take about a year for a tree branch to develop roots strong enough to go in the ground. For best results, start several branches because, no matter how closely you follow instructions, they won’t all form roots. Compost any that aren’t thriving.

For safety reasons, leaning trees are best removed by a professional, as they may often tear away from the hinge, causing you to lose control over where the tree falls. If you choose to cut down a tree leaning slightly, avoid cutting off root protrusions before you start. Make your hinge a little longer than usual by cutting it deeper (up to 30% of the diameter) and applying a wedge into the felling cut on the side the tree is leaning. Stand away from the direction the tree leans while making your felling cut.

Although the terms tree trimming and tree pruning are used interchangeably, they are very different types of tree maintenance. Tree trimming involves enhancing the appearance of your tree by removing unruly branches, providing your tree with ample sunlight and nutrients and prevents unsightly overgrowth. 

Tree pruning helps keep your trees disease-free. This process removes unhealthy growths, dead branches, and other unhealthy parts of the tree. It’s more common for deciduous and ornamental trees but not so common for evergreen trees. To determine which method you need, discuss it with a tree trimming specialist.

Any cutting of tree roots can hurt or kill a tree, which is why it's recommended you don’t do it unless the roots are damaging or invasive on a nearby structure like your home. You should never cut more than 15 percent of above-ground tree roots at one time. If you have any questions about cutting tree roots, contact your local arborist.
