Can I Use Lawn Pesticide Around Trees?

We all want great-looking lawns. So treating them for weeds is a common practice adopted by many homeowners all across the world. The problem is that weed killer doesn’t just kill weeds; it can harm many other living organisms too, including trees. This can be a big problem since trees have a significant impact on the overall appeal and value of a property. If you want to kill off weeds and unwanted grass in certain areas of your lawn, but there are trees in the same vicinity, you will need to take extra precautions.

Pre and Post-Emergent Herbicides

There are two common types of products available to treat weeds and grass. Pre-emergent lawn herbicides prevent weeds and unwanted grass from germinating, and ultimately, growing. They generally come in granule form that can be sprinkled into the soil by hand, but are only effective when seedlings have not yet appeared; they will not work against grass that grows from rhizomes. Post-emergent herbicides usually come in spray form, and can be used to treat grown patches of weeds and grass. They enter the vascular system through leaves or blades, and kill the plants from within.

Lawn Herbicides Around Trees

It is important to read all manufacturer’s instructions before applying an herbicide product around the base of a tree. Keep in mind that they are not all the same. Some herbicides contain chemicals that will quickly soak into a tree’s root system and do all kinds of irreversible damage. Look for herbicidal products that contain active ingredients like glyphosate or sethoxydim; these two ingredients are generally safer to use around young and mature trees.

Proper application is still vital when using herbicide products around trees, even if they are deemed safe. Using too much or placing it in the wrong locations can cause damage to a tree. You want to prevent chemical drifting by wrapping the base of your tree with cardboard or plastic tarp. This will protect the bark and prevent the trunk from absorbing unwanted herbicide. In fact, it is best to apply your herbicides on a day when wind is mild to prevent drift.

Alternative Weed Killers

Aside from using chemical herbicides, you can implement some alternative methods to prevent weeds from growing around the base of your trees. One of the most effective techniques is to mulch. Mulch is an excellent organic method of thwarting grass and weed seed germination. Using mulch in combination with landscaping fabric is a highly effective method of preventing weed growth beneath trees.
