Get an early start to having a beautiful, weed free lawn this year. Prevent new weeds by applying a pre-emergent weed control. Most weed preventers remain effective for about three months and then need to be reapplied. You can also use a lawn weed killer a sunny, dry day when temperatures are above 50 to eliminate existing broadleaf weeds.

On recently seeded lawns, do not use any weed controls until the new grass has been mowed at least twice.
With most weed controls, you must wait 2-12 weeks following application before you can put down new grass seed. Check the product label for specific instructions.
Fill in and repair bare spots and thin areas of your lawn with one of Merrifield’s Custom Blended Grass Seed Mixtures. Cultivate the soil, broadcast the seed and fertilize with Merrifield Select Seed Starting Lawn Food. Then cover everything with a thin layer of compost and the seed will grow as the soil gradually warms this spring.
If needed, lime the lawn to raise soil pH. Lawns prefer a pH range of 6.2 – 6.8. If your tests show a level lower than 6.0, or you have not limed the lawn in the past two years, you should lime at the rate of 50 lb. of lime per 1,000 square feet of lawn area. This will raise the pH 1/2 point. If you need to apply more lime, wait six weeks between applications.
