Nutri-Lawn follows the principles of Integrated Pest Management when dealing with weed infestations. The foundation of our approach is to create a healthy and competitive stand of turfgrass that is capable of out-competing weeds and tolerating minor insect feeding. This is a corner stone to delivering Ecology Friendly Lawn Care. Focus is placed on the environmental conditions that the turfgrass grows in.
A broadleaf weed herbicide application, if done properly, is very effective, fast acting, and affordable. We follow the principals of IPM and use technology that allows us to spot treat weeds efficiently. This means a significant reduction in the amount of pesticides used.
The need for follow-up applications will be determined by weed type (more tenacious weeds will require multiple applications), and the general condition and health of the turf.
We discourage the "weed control only" applications because weeds are often a symptom of poor soil conditions, and if the soil compaction, fertility, or watering are not being managed properly, then the weeds will simply return.
Applying a "pre-emergent" control will not control existing weeds. They inhibit future weed germination. Pre-emergent herbicides are often used to control crabgrass. The pre-emergent herbicides must be applied before the weed seeds germinate. They only work for a limited time period of approximately 45 to 60 days, with variable results, based on environmental conditions.
