Yes, pruning makes trees stronger because it fosters proper growth, weight distribution, and balance of the crown. By increasing the structural integrity of the tree through pruning, it’s less likely to experience disease, pests, broken limbs, and storm damage. Pruning the right branches and limbs is key to improving a tree’s strength and balance.

The cost of professional tree service, such as trimming, is $460 on average, but the price can range from $75 to $1,800. A more typical range is between $200 and $760. The final price depends on several factors, including the size and type of the tree. For example, trimming Crepe Myrtle trees costs an average of $80 to $400, while giant pine trees can range from $200 to $1,800. Other factors that influence the cost include the time of year, as services are often more expensive in the spring. Your location can also play a role; costs may be higher if you live in a remote area or if the tree is difficult to access. However, some professionals may offer a discount if you have multiple trees that need service.

Not all leaning trees are dangerous, but they can be a hazard as gravity may eventually cause them to fall. A key factor is whether the lean is new or has been present for a long time. Trees that have grown with a lean for years are not typically an immediate danger, but a sudden lean is a cause for concern as it often indicates weakening roots. If a tree is leaning more than 15% from vertical, you should consider having it straightened or transplanted. To be safe, it's always best to hire a professional arborist to inspect any leaning tree to assess the risk and avoid potential accidents.

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.
