"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."

"Alex and his team did a great and professional job with trimming one tree and cutting down another and removing the stump. They arrived on time and finished everything in a prompt and professional manner. They cleaned up well after all the work was done and did a great job on pruning the one tree nicely. This is the 3rd time weâ ve used their services and will definitely do so again."

"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

The recovery time for pruning depends on how much you prune, the species of tree, and how well you care for it afterward. All trees grow new wood and often sprout additional branches after pruning. Ideally, trees should recover from normal pruning after one or two years. Heavy pruning or slow-growing trees may take several years to fully recover.

Horticulturist is a broad term for any type of plant and soil expert. An arborist, meanwhile, specializes in all aspects of tree care. You should hire an arborist when you need assistance with tree-related tasks, such as pruning large trees, removing trees, diagnosing a sick tree, or emergency tree services. Horticulturists aren’t qualified to handle those types of tasks.

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.

Trees should be pruned every two to five years, depending on its age and type. Young trees should be inspected and pruned every two to three years. Mature trees should be inspected and trimmed every three to five years, and fruit trees should be pruned annually with a careful eye on seasonal growth. Evergreens typically don’t need pruning, unless branches or limbs are damaged, diseased, or harboring pests.

Late August, September, and mid-October are the ideal months for planting a young tree. However, the best time to plant a tree ultimately depends on when the weather transitions to fall-like conditions and eventually winter frost. As long as the hottest days of summer have passed and the ground hasn’t frozen yet, you can still successfully plant trees.
