Cool Season Weeds

Now that high temperatures are hitting the mid 70’s in my area it is time to start thinking about preventing cool season weeds. Before tackling a weed control program it is important to know that complete suppression of any weed from your yard is not practical. It is only possible to manage (not eliminate) the weeds by reducing the invasion to an acceptable level. The best method for preventing a weed problem is maintaining the health and density of your lawn. Accurate mowing height, irrigation and fertilization of the grass are the best defense against weeds. With that done; pre-emergence herbicides should be applied to well-established lawns in late summer or early fall. In this area sometime around Halloween seems to be a good time.
Keep in mind that you'll never get rid of all the weeds in your lawn. The wind will blow weed seeds from nearby lawns into your lawn, birds will deposit them and kids running from one lawn to the next will transport weed seeds on their shoes. So do what you feel you must to battle the weeds in your lawn, but do it wisely.
