When to Plant Grass Seed in Oregon

Published Categorized as Turfgrass

Does your Oregon lawn look neglected, sickly, or display bare spots? No worries. You can re-establish new grass by seeding the bare patches instead of buying expensive sod to install a new lawn. Sounds great, right? However, timing is everything when reseeding in this region. So, let’s learn when to plant grass seed in Oregon.

The best time to plant grass seed in Oregon is between the spring and fall months when the turf is actively growing. This is between 1st September and 15th October or between 15th April and 15th June. During this period, the conditions are ideal for most cool-season grasses. It’s worth noting that planting in the early spring will give turf a longer growing season. This allows the lawn to become more established, unlike when you plant during the summer months.

When to Plant Grass Seed in Oregon

Seeding is the best way to repair bare patches and thicken your lawn. If you need to know when to seed lawn in Oregon, the best time is spring and fall. This should be around September 1 and October 15 or between April 15 and June 15. During this time, the grass is actively growing, making the lawn more established.

In October, most gardeners wonder if it’s too late for lawn seeding. It’s a great idea to plant seeds in October, as they will have a good chance of surviving the upcoming winter. Although September is typically the best time to reseed, you can do it until October 15.

You can also plant grass seeds between March and October, but keep the seedbed moist during dry days. But note the summer heat will kill the grass or give the lawn weed problems, making it difficult to establish. Therefore, sow grass seeds in Oregon during early spring or late fall.

Best Grass Seed for Oregon

There are various types of grass seeds that you can plant in Oregon, depending on your area and the climate. Generally, the region has a cool, moist climate, and the grasses that thrive in this climate include bent grass, fescue, ryegrass, and bluegrass.

1. Bentgrass

Bentgrass is among the well-established grass varieties in Oregon soil. It’s bright green, durable, and handles heavy mowing just fine, making it a perfect choice for the traditional lawn. However, it requires plenty of moisture to flourish, so you must water frequently.

2. Bluegrass

Most homeowners in Oregon prefer planting Kentucky bluegrass due to its beautiful, lush color. It is also highly disease-resistant and can tolerate cold temperatures, shade, and heavy foot traffic.

3. Ryegrass

You can reseed your lawn with ryegrass if it’s suffering from recurring crabgrass. The grass is also excellent in areas that receive high foot traffic. However, although durable, it is vulnerable to extreme cold and droughts.

4. Fine fescue

This is another option that flourishes in Oregon lawns. It is easy to maintain, has shade tolerance, and requires occasional irrigation.
