"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."

"ETC has true arborists in it. They know trees and they can remove them with the minimum of damage. My wife has plants everywhere and they avoided damage to far more of the plants than we had hoped. I asked them to do some extra work at the time and they got it done, too. At my son's house he pointed out that the Oak he had could only be worked on after the beginning of November or it could harm the tree, too. That's what I mean that they know trees and have true arborists doing the removal. They do my house and my son's and I have recommended them to several people. I have no connection to them EXCEPT as a happy customer."

"Beaver Jacks team of employees worked efficiently to trim trees and shrubs beautifully. They also removed a large shrub. Andy an arborist was my first contact . He made suggestions to perserve the health and beauty of trees and shrubs that I identified. Then he clearly described the plan and gave me a detailed estimate. Communucation was excellent from the office as well as all the personnel on the day they arrived. I want to thank the friendly ,kind staff for thier excellent job and care to make sure the job was completed as I requested. The clean up was awesome! Thank you to: John, Preston, Jake ,"T", Logan, Devlin and Tyler! Great Job!!! Would reccomend this company to my family and friends!!"

Arborists FAQs, answered by experts

Yes, cutting a tree's roots can cause it to fall, particularly if major support roots are severed. In extreme cases, trimming roots can affect the tree's structure and stability. Many crucial roots are located just below the soil's surface. If you make severe cuts to roots more than 2 inches in diameter, you risk impacting the tree's water flow and its ability to withstand severe winds or storms. Even cutting roots less than half an inch in diameter under or outside the tree's canopy can cut off its water supply, causing it to decline, die, and eventually topple.

Yes, it is highly recommended to remove tree stumps. Leaving them in the ground can lead to several problems, as they are not only unsightly but can also reduce your property's value. Stumps can obstruct landscaping plans, make mowing difficult, and hinder new growth. More importantly, they are prime breeding grounds for pests like termites, ants, and mice, which can spread to your home and cause costly damage to its wood and foundation. Stumps also attract fungi and diseases that can infect other healthy trees and plants in your yard. As a stump decays, it might sprout new, unwanted shoots. While removing a stump is an investment, it prevents these potential issues and enhances the safety, health, and appearance of your landscape.

Professionals use assessments, strategic cuts, specialized equipment, and safety measures to ensure healthy growth or the safe removal of trees or shrubs.

An arborist specializes in tree care, performing tasks such as pruning, treating diseases, and removing hazardous trees. They also assess soil conditions, plant trees, and develop landscaping plans to ensure healthy growth. They also manage debris cleanup, inspect equipment, and record maintenance activities. Arborists often collaborate with landscapers and professional tree maintenance services, applying their specialized knowledge and problem-solving skills to maintain tree health and safety.

Completely topping a plum tree is a risky business. Cut too much, and you’ll kill your tree. That said, you do need to trim the top of your tree to encourage bushy growth, maintain your tree’s vase shape, and limit size. 

A plum tree's central leader (or trunk) should never extend more than 3 feet above the highest branch. When you first plant your tree, cut the central leader so it’s 2 to 3 feet tall. As it grows, cut it back 12 to 20 inches until it reaches its desired height. Never prune more than one-third of the new growth.
