Best Weed Preventer Buyer’s Guide
Applying the best weed control in your lawn will help you to grow a healthier and weed-free lawn. Here is the definitive guide for selecting the best weed preventer for you.
If your lawn was affected by weeds last season. Then, there are most chances that your lawn will also affect the incoming season. So, you need a weed preventer to stop the germination of weeds.
Things to Consider When Purchasing the Best Liquid Weed and Feed
Many homeowners would prefer to grow a natural lawn with little use of pesticides. But most will find out the hard way that growing a pesticide-free lawn is very difficult if not impossible. The best option for homeowners is to prevent weeds from ever occurring in their yard. This means being proactive and getting a jump start on any potential weed problems before they even have a chance to take hold.
Purchase a Pre-emergent Lawn Care Product
The two types of pre-emergent pesticide products are organic and chemical. The main difference is the chemicals can last for months after application, while organic versions must be applied more frequently throughout the season.
Pre-emergent fertilizer products will contain nutrients that “feed” your grass so it’s better able to compete with weeds once they emerge. This product also helps soil retain moisture, which means you’ll need less water regularly. Keeping the grass healthier means fewer weeds will grow because there’s no room or resources left for them to expand their colonies.
Prevent Weed Seeds From Sprouting
You should only apply pre-emergents when conditions are favorable, which typically occurs in early spring or fall. In some areas of the country, applying a pre-emergent product is not practical because winter temperatures are too warm for the chemicals to work their magic. In this case, you’d have to wait until next year’s fall season to apply a pre-emergent chemical treatment.
If an organic product is your preference, spread it evenly across your entire yard and water it immediately after application. This allows the nitrogen fertilizer to get down into the soil so grassroots can absorb it easily when they emerge from dormancy. You should water at least 1 inch of rain or liquid per week during spring through early summer months when weeds are likely to germinate. If needed, you can apply more fertilizer 2 to 4 weeks later.
Tips & Warnings For Using Weed Preventer
Mow the area 24 to 48 hours before you intend to treat it with the best weed control formula. Measure the length and width of the section of lawn you wish to treat. Multiply length times width to get the total area in square feet. If the area is an irregular shape, break it into square or rectangular sections. Then add those areas to give total square feet to be treated.
Water thoroughly the area to be treated the evening before you intend to apply weed control. You won’t be able to water again until 48 hours after treatment. This will keep the lawn hydrated. Calculate how many pounds of weed control you need to treat your total each 1,000 square.
Do not apply more than two times per year. Allow 30 days between applications because the product leeches into the ground when watered in. And should not be applied in areas with tree roots or plants you want to keep.
