Overseeding is spreading grass seed over an existing lawn. Done right, it's a straightforward process that gets results. As grasses mature, thinning is normal—especially if you enjoy your lawn and use it often. Overseeding keeps your lawn competitive and steeped in youth and vigor, without starting over from scratch. via
How do you overseed a lawn?
When should I overseed my lawn?
Best Time to Overseed
The first is late Summer to early Fall, because it helps to give the grassroots a chance to become established before Winter. You can also overseed in the Spring months before Summer, as this is another high growth period for your grass. via
Does overseeding actually work?
Proper overseeding can renovate a lawn if it has at least 50% or more healthy turf. However, if your lawn has less than 50% healthy turf, it may be better to kill out the old turf, weeds, etc., and reseed the entire lawn. via
Why is overseeding bad?
Overseeding literally means putting turf grass seed over an already existing lawn. Your bare or thinning lawn may be damaged from drought, heat, insects, weeds, or from overuse resulting in compaction. Poor management practices and a lack of knowledge can also result in lawns that look lousy. via
Can you just throw grass seed down?
Grass seed will grow if you just throw it on the ground, but the quality won't be as high as if you prepared the soil beforehand. If you throw grass seed on compacted soil, it won't germinate as well as it would if the soil was prepared. via
Can you throw grass seed on existing lawn?
Overseeding. Sowing new grass seed over your existing lawn is known as overseeding. While it's possible to simply sow the new grass seed over your existing lawn, taking the time to prepare your lawn beforehand will increase the likelihood of seed germination and improve your end result. via
How do I make my grass thicker and greener?
What is the best grass seed to use for overseeding?
For instance, Kentucky bluegrass is the best grass species for overseeding if you want to maintain a healthy, lush look and heal damaged parts of the lawn and enhance its tolerance to cold weather. For low-maintenance lawns that don't need much fertilization, tall fescue is the best grass seed for overseeing. via
Do I need to aerate before overseeding?
The best time to aerate your lawn is during the fall before you begin a fertilization program or decide to overseed. Aeration will help ensure your soil is ready to absorb all of the nutrients and seeds that come its way with topdressing and overseeding. via
Is it best to aerate before seeding?
As with most larger lawn projects, such as planting grass seed, it's best to aerate during or right before the time your grasses reach their peak time for natural growth. When aeration coincides with active growth, grasses recover quickly and fill in areas where aerator equipment exposes soil. via
Should I mow before overseeding?
Mow Low. Before overseeding your thin lawn, cut your grass shorter than normal and bag the clippings. After mowing, rake the lawn to help loosen the top layer of soil and remove any dead grass and debris. This will give the grass seed easy access to the soil so it can root more easily after germinating. via
How much water should you drink after overseeding?
You should get about one inch of water each time you water for a total of three inches per week. You can also use a rain gauge to measure rainfall and adjust watering accordingly. via
Should I fertilize after overseeding?
Lightly water the lawn immediately after overseeding. Always wait until the grass is dry before you mow. Fertilize the lawn about six weeks after you sow the seed. via
How do I fix overseeding my lawn?
Can you walk on grass seed?
Avoid walking on a newly seeded lawn and any new grass that is under 3 inches tall. Wait until the new grass is over 3 inches tall before mowing, to prevent uprooting or killing young grass. Once the grass has been mowed at least 3 times, it is established enough to be walked on regularly without causing harm. via
Does grass seed need to be watered daily?
Normally a lawn should be watered deeply but infrequently, but when you are watering for new grass seed, you must water every day. Twice daily watering is essential until the new grass is up, then after one more week, reduce to once per day. Adjust this pattern according to season and temperature demands. via
What happens if you don't rake in grass seed?
If you do not rake the area or cover it thickly with soil, the grass seeds fail to grow from erosion issues and suffocation, respectively. You should be able to see some seeds poking out of the soil with a proper raking. In addition, your watering regimen should not erode the seeds from the area if they are raked in. via
How can I thicken my lawn?
Should I leave grass clippings on lawn?
It's a question we all face when mowing the grass: Should I bag my clippings or leave them on the lawn? In most cases, the answer is easy. Recycle the grass clippings by leaving them on the lawn. Doing so will not only save you time and energy, but will also return valuable nutrients to the lawn. via
What fertilizer makes grass dark green?
After turf grass selection, fertilization is the most important factor in growing a dark-green lawn. To encourage green growth, choose a lawn fertilizer with a high percentage of nitrogen and a low percentage of phosphorous. via
Does frequent mowing thicken grass?
Mowing actually helps make your grass grow thicker because the tip of each blade contains hormones that suppress horizontal growth. When you cut the lawn, you remove these tips allowing the grass to spread and grow thicker near the roots. via
Can I mix grass seed types?
Mix. When selecting a type of grass seed, you can choose one specific seed type or a blend that combines several different species. Go for a single seed type if you're trying to achieve a particular look for your lawn. via
What's the difference between seeding and overseeding?
Overseeding is a process of using a broadcast spreader to apply grass seed on the surface of the ground. Slit seeding is a process of utilizing a machine with knife blades to create slits in your lawn, which allows grass seed to drop below the surface of the ground, maximizing the percentage of germination. via
How much seed do I need for overseeding?
Overseeding requires about half the normal seeding rate, or the rate that would be used on bare soil, including totally bare spots in your lawn. For tall fescue, the normal rate is generally 6 to 8 pounds of seed per 1,000 square feet on bare soil. via
Is it better to aerate or dethatch?
So should you dethatch or aerate? Core aerating not only breaks up thatch buildup but also relieves compacted soil. Dethatching mostly loosens the top layer of soil and also removes the layer of debris (dead grass) from the soil. Dethatching can really help when overseeding your lawn. via
Do I need to rake in grass seed?
Raking is necessary because the seeds need to come in contact with the soil to germinate properly. You will still see some seeds poking out after raking but you will not see the seeds erode from the soil after watering. This is important because a newly seeded lawn will need to be watered at least every other day. via
Does aeration and overseeding work?
Yes, Aeration and Overseeding Can Work For You
Aeration and overseeding does work, and it can work for you if you choose to let it. via
What fertilizer should I use when overseeding?
Starter fertilizers vary, but most are either a 10-10-10 or a 20-10-10 formulation. The extra nitrogen helps green up the existing grass as well as feed the fescue as it germinates and grows. Apply at a rate of 1/2 to 1 pound of nitrogen per 1,000 square feet of lawn. Water thoroughly after fertilizing. via
Can I mix grass seed with compost?
Mix the seed in a bucket with equal proportions of a suitable carrier such as general purpose compost and sand; a light garden soil could be used but would need to be sterilised in order to eliminate the numerous weed seeds liable to be present. via
How much will a 50 lb bag of grass seed cover?
If your question is, “does a 50-pound bag of grass seed cover the area I want” then read the bag. Don't just buy a bag and hope it's enough. Read, then follow the recommended guidelines. Most seed bags will recommend a range such as 250-400 square feet per pound. via
How long after overseeding can I mow?
You mow too soon.
After you lay down your seedlings, they'll need time and the right environmental protection to grow. They'll need to acclimate and set roots before the first mow, so during the first two to four weeks post aerating and overseeding, don't mow. via
Will grass seed grow without watering?
Not only do you need your soil to be the right temperature for germination, the most critical component of germination is appropriate moisture. To sprout, the seed needs to be moist and warm. Without enough water, grass seed is unlikely to sprout, and without some sort of mulch or top-dressing, most seed will dry out. via
Should I bag or mulch after overseeding?
A mulch over your newly overseeded lawn is helpful but definitely optional. The most important benefit of a mulch is to reduce water evaporation and therefore reduce the chances of the grass seed drying out and reducing seed germination rates. via
