Summer Lawn Seeding? You May Want to Wait.

Lawn seeding success is largely dependent on the weather and fall is generally the best time to do it. That’s because there are a few things working against summer seeding and establishment.

The first is higher soil temperatures. While warmer soil is generally good for seed germination, it impedes root growth and the development of seedlings. In addition, longer days with more sunlight and higher air temperatures can cause quick evaporation of moisture from the seed bed.

If you do decide to go ahead with summer lawn seeding, frequent irrigation will be very important (this can be a problem if drought conditions lead to watering restrictions in your area).

For best results, you’ll need to water early in the morning (before 9 a.m.) and again in the afternoon between 2 p.m. and 4 p.m. to prevent drying.

If you foresee problems with providing consistent, timely irrigation this summer, you’ll probably be better off waiting until fall arrives to seed your lawn.
