When To Start Seeding Grass

Planting in late spring and early summer gives warm-season grasses the advantage of warm soil and early seasonal rains, which help keep soil moisture available during germination and establishment. Moderate spring weather helps spring-planted grass seed flourish.

Is it too early to seed my lawn?

It would seem that it is never too early to sow grass seed in the spring. Throwing seed down before the snow has melted or seeding before the last snow is often recommended. Grass seed will not germinate until daytime temperatures begin to average 60 to 65 degrees.

What month should I plant grass seed?

Although you can sow grass seeds at any time of the year, it is best to sow in spring or autumn where possible. In the autumn you can expect fewer problems with weeds and the rain will make it easier to keep the seedbed moist and the soil temperature will still be high.

When should I seed my lawn in the spring?

Aim to seed early in the season, but wait until daytime temperatures are in the 60 to 75 degree Fahrenheit range. This roughly corresponds to the optimal soil temperatures for cool-season grass seed germination. Spring sunshine and rain both contribute to strong grass growth.

Can you just sprinkle grass seed on lawn?

Can you just sprinkle grass seed on top of your existing lawn? 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.

Is March too early to plant grass seed?

In nearly all regions, March is too early to plant grass seed. Temperature is a better barometer; wait until days average about 80 degrees before planting grass seed for summer. March is too late to sow cool-season grasses.

Is it OK to overseed in the spring?

There are two ideal times of the year to overseed your lawn – fall and spring. Fall is the best choice. Also, weed growth tapers off after summer, so your new grass won’t have to compete for sunshine, water, and nutrients. Overseeding in spring is the next-best option.

What temperature is too cold for grass seed?

If you’re wondering how cold is too cold for grass seed germination use our rule of thumb and check the weather reports. If the daytime temperature is below 60°F then soil temperature is below 50°F, making it too cold; if there is frost or still a danger of frost, then it’s too cold.

How long does it take grass seed to grow in April?

Assuming optimal weather and growing conditions, some seed can germinate in as quickly as 4-7 days , or it can take as long as 21 days before germination begins.

Is April a good time to plant grass seed?

If you have your heart set on planting grass in spring, early April is, in fact, the best time to do it. But, depending on where you live, spring seeding could come with complications. Stressful summer heat could slow or completely stop the growth of cool-season grasses.

Should I put topsoil over grass seed?

You don’t need to turn the topsoil over. Just break it up so the new grass seeds’ roots can easily grow through. If you just have a small area to seed, a digging fork will do the trick. For larger areas, consider a core aerator.

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.

Can I put topsoil over grass and reseed?

Adding soil over grass can be another effective form of repairing a lawn. It is possible to dump new soil over top of what you have, and prepare it for sod or seed. If you are not putting down a thick enough layer of soil to kill everything underneath, you may have to make some other choices.

Do birds eat grass seed?

Even after your grass seeds have germinated and you get a nice, new lawn growing, there’s still a chance that birds will eat the grass. Some birds, such as finches and parrots, enjoy the young blades of grass, especially in spring.

Can you plant grass seed in December?

Grass seed can survive the winter, and planting during the winter season is known as dormant seeding. If you put down grass seed in November or December, the seed will just lay dormant until the soil starts to warm in spring. While this comes with risks, it can also be beneficial and save you time on seeding in spring.

How late can you plant grass seed?

Although September is the best time, often we can still plant grass seed up to October 15 with good results. The problem with late season seeding is that Mother Nature is working against us. Shorter days and cooler temperatures prolong the germination of the seed and its establishment.

Do I need to fertilize when I overseed?

Overseeding Maintenance Always wait until the grass is dry before you mow. Fertilize the lawn about six weeks after you sow the seed. Apply a pound of quick-release nitrogen fertilizer for every thousand square feet of lawn space.

Do you 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. Aeration is good for lawns, but it can stress grass if timed improperly. Overly dry soil can be tough to aerate, so moisture eases the process.
