The safest way to cut down a tree is to make sure you’re completely prepared and have done all the necessary safety checks, including double-checking your equipment is in good working order, you have plenty of clearance to fell the tree, you’re wearing all the safety gear, and you have a partner to help you (who should also be wearing safety gear). 

Most tree surgeons cost around $100 per hour or between $70 and $200 per hour for their services. You might get flat fees for more straightforward services, like a tree assessment, tree removal, stump grinding, and one-off treatments, but many times, treatments for tree diseases or pests will be charged based on an hourly rate or a per-visit rate. Since the cost of a tree surgeon can vary widely, it’s best to speak with an arborist near you to get an idea of what your particular issue will cost to correct.

The ideal depth of a tree notch depends on the tree, but it should usually be between 20% and 25% of the tree’s depth. However, if the tree is leaning towards the direction of the notch, it can be cut more shallowly—at as little as 10% of the depth. When the tree is leaning away from the direction it needs to be felled, you can cut deeper, closer to 30%.

Whether tree roots will continue to grow after a tree has been cut down depends on the species. Some tree roots will eventually die because they can no longer get nutrients through photosynthesis. However, other species that reproduce through root sprouts can continue to grow and produce new sprouts for seven years or more. For example, the roots of elms, ficus, and willows tend to regrow aggressively, while the roots of pines, oaks, and maples will typically die. To determine if a root system is still active, look for new sprouts on the old trunk, stump, or any exposed roots.
