IPM Weed Control

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.

  1. Ensure proper soil fertility, aeration, and soil pH. Without good soil your lawn will not compete well with weeds. Nutri-Lawn programs are designed to encourage healthy soil for your landscape.
  2. Water your lawn properly. This is also critical if you hope to maintain a thick, beautiful lawn. Over watering or under watering of a lawn can lead to weed infestation.
  3. Mow at the right height. Unless you have a bentgrass lawn, your mowing height should be up at 2.5” to 3.5”. Mowing too short can encourage weed infestations.
  4. Mow once a week. Rule of thumb is not to remove more than 1/3 of the leaf blade. Scalping a lawn by cutting too short or waiting too long between cuts and then cutting short can set back a lawn for weeks.
  5. Annual aeration with an overseeding or slitseeding will introduce new vigorous cultivars of turfgrass and help keep the lawn thick so weeds are crowded out.
  6. Apply Organic Plus Topdressing to add nutrients, and organic matter to your soil, without the fear of weed seed. Other topdressings can be full of nasty weed seeds.
  7. Consider hand-pulling the weeds. Two people and a couple good weed pullers can go a long way. Think of it as good exercise. After hand-pulling, it is strongly recommended to overseed the bare soil areas left from pulling the weeds and apply a starter fertilizer. This will help stop weed seeds from getting established in these spots. Hand picking weeds to establish weed control will only address the present weed problem, but does not address the source of the problem. Simply hand weeding does not prevent or discourage new weeds from getting established. Hand-pulling should be considered as simply one part of the whole approach, which includes regular feedings, core aeration and annual overseeding.
  8. Follow the principals of IPM. If hand-pulling is not an option, then consider using our IPM (Integrated Pest Management) programs that are designed to control pests using a multitude of approaches, including the responsible and professional use of pesticides. We strongly recommend that you use a professional, licensed service like Nutri-Lawn, when dealing with pesticides.

Regarding Weed Control With Herbicides

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.
