You may have a few weeds. It happens to everyone. Will grass seed still be able to thrive and grow amidst a few weeds?
If you do see any weeds pop up in the grass seed area, pull them right away! Don’t use a weed killer quite yet. Your new grass can’t handle an herbicide at this stage.
Do I need to remove weeds before overseeding?

Look for a reputable brand of grass seed. It should list “weed seeds 0%” and “other crop seeds 0%”.
Weeds are frustrating! With a bit of patience and work, you can take back your yard with new, healthy grass!
If you are faced with a neglected lawn that’s partially dead and is being taken over by weeds, you may be able to renovate it. Restoring a deteriorated lawn may be possible if the weeds and dead spots cover less than 40 percent of the lawn area. Renovation of a weedy lawn involves more than just mowing down the weeds and throwing some grass seed over the lawn.
Most deteriorated lawns have a built-up layer of dead and partially rotted grass stems, roots and rhizomes just below the green grass leaves. This is known as thatch, and it must be removed before reseeding so water and fertilizer can reach the new seed. For small lawns, you can remove thatch with a garden rake. For large areas, go over the lawn with a power dethatcher, also known as a vertical mower or power rake. These machines can be rented from garden centers. Remove the clumps of matter left by the machine with a garden rake and level the soil by raking it.
Kill the Weeds
The soil nutrients most important to healthy grass plants are nitrogen, potassium and phosphorous. Supply these nutrients by applying a commercial fertilizer formulated for starting lawns and lightly rake it into the soil before you reseed. Buy a grass-seed blend suited to your climate and local conditions and spread it over the lawn with a drop spreader or rotary spreader. Absent a different recommendation from the grass-seed grower, spread the seed at a rate of 2 pounds per 1,000 square feet on a lawn with substantial plots of live grass and 3 pounds per 1,000 square feet on bare soil. Water lightly once or twice a day to keep soil moist but not sopping wet. Don’t mow until the new grass gets 3.5 inches tall.
The best time for lawn renovation throughout the U.S. is mid-August to mid-September. Most weeds have not yet dropped their seeds and there will be little new weed growth. Also, reseeding at this time will give the new grass a chance to establish itself before going dormant for winter. Get rid of the weeds by manually pulling up large, spreading weeds. Follow up by applying a selective herbicide product that kills common broadleaf lawn weeds while not harming grass. For tough grassy weeds, like quack grass or crabgrass, use a nonselective herbicide such as glyphosate on the spots where these weeds have established themselves. Normally, all weeds will be dead within two weeks. Apply another herbicide dose in three weeks to get newly sprouted weeds.
If you have had a dry summer with below-normal rainfall, you need to replenish soil moisture before preparing a seedbed. Give the entire lawn a thorough watering, soaking until water has penetrated to a depth of at least 6 inches, then allow the surface to dry for a day or two before starting soil preparation.
Historically, it has been extremely difficult to create a fine Zoysia grass lawn from seed. However, Zoysia seed has come a long way over the last few decades. It now germinates better producing a beautiful lawn, but still has some very particular requirements in order to be successful. Our experience is that it is possible to establish a lawn from the Zoysia seed and we now are making available Zoysia seed to homeowners. We only supply what we believe to be the best of the best and the one that meets our standard for quality and durability.
Amazoy Freestyle Plugs are shipped in 10" by 15" sheets of grass. Each sheet can produce up to 150 — 1" square plugs. The plugs can be cut bigger, that’s the freestyle part. Bigger plugs means less cutting and less planting, but you will get less plugs from each sheet.
There are very specific requirements for how deep to plant the seed, the amount of light it needs, and watering. It will be important to follow the seed planting instructions carefully for success.
Zoysia is a particularly hardy grass that grows well in a wide range of conditions and requires far less watering and mowing than most grasses. At the same time, this “tough” grass creates a thick, soft carpet that feels great in bare feet. Zoysia is ideal because it actually grows differently. It sends out runners or “stolons,” expanding sideways more than it grows tall.
After the plugs are established, you can minimize the effects of pet waste by periodically liming the soil in order to restore the pH level to an acceptable range between 6 and 7.
To determine the pH of your soil, use a pH meter or soil testing kit. We offer an easy to use pH Meter and Soil Test Kit.
Zoysia is more tolerant to pet urine and feces than most grasses. However, no grass will survive prolonged or constant exposure to pet waste. Pets should be kept off of the new plugs for at least 30 days in order for the plugs to become established.
