The best way to control weeds is to have a healthy lawn that chokes them out before they get started. Don't mow your lawn too short, be sure to fertilize adequately, and water deeply. Beginning a good maintenance program will bring many weeds under control within one growing season without chemical intervention.
Which Weedkiller Should I Use?
Before applying any chemical, know what type of grass you have and the type of weed you want to kill. Always read and follow product labels carefully. Call your local lawn service company for any questions regarding this task.
Pre-Emergent?
A pre-emergence weed killer is applied before the seeds germinate in the lawn. Some of these products are combined with fertilizer, and others are sold separately.
Post-Emergent?
A post-emergence weed killer eliminates the weeds that you can see. It may be combined with fertilizer in a product called weed-and-feed, or it may be sold separately as granules or as a spray. To be most effective, it should be applied to the lawn in warm weather when the weeds are growing.
