We’ve enjoyed a good amount of spring rains in April and now into May, which is nice for the lawns and landscapes in Tulsa and Oklahoma City. But weeds are flowers also, which is the way they naturally reproduce, so they are out in full force also. The best defense against weeds is always a thick, healthy, growing lawn, which makes it more difficult for weed seeds to get to the soil and helps choke out existing weeds. And even with a nice turf, and with fall and spring pre-emergent herbicides applied, one will still have a few weeds pop up, especially in mid to late spring.
This is where post-emergent herbicides come into play, which are mixed with water and sprayed on existing weeds to take them out. Weeds are generally classified into two main groups…..broadleaf and grassy weeds, or dicots and monocots for those who paid attention in science class. Different types of herbicides are applied according to the main types of weeds they are. So other than a product such as Round-up or Glyphosate, which kills anything that is green, good or bad, it pays to have a professional such as LawnAmerica make those decisions as to what to use and how to use it.
Spot-treatment for weeds present, and they usually are, is a part of our regular lawn care service programs. We practice something called Integrated Pest Management, or IPM at LawnAmerica. This basically means we only treat for weeds if there is a weed on a spot-treatment basis for most of our applications. We do this with a backpack sprayer with specific products intended to control certain weeds. So during the main part of the growing season, after applying a granular fertilizer or a liquid organic-based soil amendment to a lawn, we’ll go over it and spot-treat any existing weeds present.
Service calls are also free for full program customers, as long as it’s been less than 30 days from one of these regular lawn treatments. So we encourage our customers to contact us if weeds are persisting, as they sometimes can during rainy spells in May.
