Things to Remember with your Trees
- Do not top your trees. Topping a tree promotes sucker growth and produces multiple weaker branches at the top of tree.
- Cut dead wood out of trees and shrubs.
- Monitor for insects and only treat them when the tree cannot support the number of insects and/or they are causing physical damage to the tree.
- Keep vegetation within the right-of-way and at corner lots at acceptable heights (below 3 feet for visibility reasons).
- Remove tree suckers Opens a New Window. from base of the trees.
- Water young street trees (planted 2 years or less) at least once a week with approximately 15 gallons of water.
- Remove the tree stakes from young trees after the first year. Tree stake ties will prohibit proper growth if not removed.
- Don’t dump landscape materials into the street. During heavy rain events it will wash into the inlets and plug the water’s way, which could cause flooding.
Tree Pruning the Basic Cuts
It is important to prune your tree the right way, the health of the tree depends on it. Whether you are training a tree to grow a certain way when it is young or removing dead branches. If you cut them the proper way it will heal better and be less susceptible to problems, such as: Cutting too close into the branch collar will cause the tree to not heal over correctly and may cause a cavity to form over time; also cutting too far away from the branch collar will cause a branch stub which will prevent the tree from healing over the part of the branch left over. Below is a diagram of the three-cut method that will insure that a proper cut has been made.
- First make a bottom cut to prevent peeling of bark down the side of the tree trunk.
- Then cut off the bulk of the branch.
- Last step is to cut off the remaining stub at the branch collar; this enables the tree to compartmentalize over the wound.
If these instructions are followed your tree will be in good health and after time the cut will no longer be noticeable. This is the basic technique for removing small 1 ½ inch to 4 inch branches. Branches less than 1 inch may only require one cut, And branches over 4 inches may require many other cuts further out on the limb to remove more end weight prior to finishing with step 3.
