Types of Weed Control

Weeds can be a real pain in the old garden or grass. Seemingly impossible to kill and hard to control, weeds prevent the growth of your plants and use up resources in the lawn and garden. Controlling weeds requires equal parts chemical, cultivation and manual control methods.

Cultural Weed Control

Cultural practices prevent the growth of new weeds and kills old weeds through regular soil care. Mowing your lawn prevents weed germination, as germination occurs when lawn turf density is decreased. Fertility of desirable plants helps prevent weed damage when they do grow. An application of nitrogen to soil along with chemical weed control promotes the growth of healthy, desirable plants. Preparation of soil in a garden with disease free, porous soil keeps plants healthy and makes weed management easier. Tilling garden soil before planting helps control weed germination and destroys weed root systems.

Manual Weed Control

Pulling and digging up weeds is an organic and chemical-free method of weed control. Pulling weeds before they release seeds prevents the spread of weeds throughout the garden and lawn. However, some weeds have deep root systems that will continue to grow if not removed properly, making this method inconsistent.

Chemical Control

Chemical control requires the application of herbicide to either prevent weeds or remove them from the lawn. Herbicides come in pre-emergence formulas, which attack the seeds that grow into weeds, and post-emergence herbicides, which poison the full-grown weeds. Herbicide types break down further into selective herbicides, which target weeds only, or nonselective formulas, which will kill or injure any plant it comes in contact with. Application varies among herbicide varieties. Most herbicides are applied to the foliage while others are applied directly to the soil.
