    Do I need to aerate before overseeding?

    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?

    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.

    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.

    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.

This is important because a newly seeded lawn will need to be watered at least every other day. via

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

    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.

    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
