In Washington, April and May are considered the best time to sow cool-season grasses, according to the Washington State University Extension Service. The second-best time is August and September. In western Washington, where winters are milder, reseeding can occur as late as mid-October with satisfactory results.
What is the best grass in the Seattle area?
- Fine Fescues. All main varieties of fine fescues grow well in the Seattle area, including creeping red fescue, chewings fescue, hard fescue, and sheep fescue. With all four of these, you can expect a lawn that has fine blades, a high shade tolerance, and low maintenance requirements.
When should I plant grass seed in the Pacific Northwest?
The Best Time To Overseed Grass
- Pacific Northwest (Washington and Oregon): Plant new grasses about six weeks before the first projected snowfall.
- Southwest U.S. (California and Arizona): Early spring is the best time for overseeding in these areas.
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.
How early can I plant grass seed in the spring?
Spring seeding is your second best option for planting cool-season grasses. 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.
What month should I put grass seed down?
For best results, lawn seed should be sown in spring (from March to May) or early autumn (September to mid October), when the soil is moist and warm. Before laying a new lawn, take some time to think about the part it will play in your overall garden layout.
How cold 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.
Is it too late to 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.
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.
Can you plant grass seed in April?
Stressful summer heat could slow or completely stop the growth of cool-season grasses. So yes, you can plant cool-season grass in spring, and you should shoot for April if you’re doing so. But, your lawn will have a much better chance at survival if you wait until later in the year.
What temperature can I plant grass seed?
They grow most actively when air temperatures are warm, between 70 and 90 degrees F. In addition, seeds need warmer soil temperatures than cool-season grasses to germinate (ideally between 65 and 70 degrees F ).
Is it OK to plant grass in the spring?
Spring is a good time to plant a new lawn or rejuvenate an older one. Select warm-season grasses, such as Bermuda or Centipede, for spring grass planting. Warm season grasses are a bit more difficult to start from seed, but proper preparation creates a seedbed conducive to healthy and rapid growth.
Is it OK to overseed in the spring?
If you live in the North and are unable to overseed in the fall, your next best time is the spring. If you live in the South, the best time to overseed is late spring through mid-summer, since warm-season grasses need warmer soil temperatures to germinate.
Will grass seed grow if you just throw it on the ground?
The simple answer is, yes. Beyond just throwing the seed out into the lawn and not performing any grass maintenance there is a whole world of lawn care. Basically the grass will not grow if no grass maintenance has been completing prior to planting and it is just thrown on the ground.
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.
Can new grass seed survive a frost?
The easy answer is that frost will not kill grass seed, but that does not mean that you should plant grass seeds when there is danger of frost. While the seeds will survive until the next growing season, any seeds that sprout into seedlings will not.
