Why is tree pruning important?

What’s the purpose of stump grinding?

After a tree is removed, the stump remains. Digging out the roots would leave a massive crater. Leaving the stump in place can be unsightly, a safety hazard, and annoying to mow around. And that’s not to mention that it takes up space in your yard that could be used otherwise.

A stump grinder can solve this problem by grinding the stump into mulch (the grinder will penetrate about 8” beneath the surface to ensure that erosion doesn’t cause the stump to resurface). The process is quick and affordable and eliminates the hassle of an unsightly, unsafe tree stump in the middle of your property.

Are trunk injections valuable?

Typically minor pest problems that do not cause serious harm to your tree can be handled without pesticides. Certified arborists trained in Integrated Pest Management or IPM, will have the insight to know when pesticides are needed in addition to PHC based on environmental conditions, seasonality and other factors.

Do trees need to be fertilized?

Depending on the condition of your soil and other environmental factors, your trees may need to be fertilized to stay strong and healthy. >Deep root fertilization restores essential nutrients that your tree may not be receiving.

Most trees will not need fertilization annually, and over fertilization can have adverse effects on the health of your tree.

The first step is to determine whether any action is necessary. In certain situations treating a cavity can cause more harm than good—an experienced arborist will be able to make a recommendation on what, if any, action should be taken.

Additionally, avoid painting pruning cuts.

Can you reduce a tree’s size?

Trees should NEVER be topped. This is a dangerous practice that not only harms the health of the tree, but also makes them less safe and more likely to fall.
