Thanks for reaching out. What part of Colorado are you in?
Aeration and overseeding do wonders for your lawn, especially in the spring!
Before we get started, a few tips:
- Before you start, cut your grass to about 2 inches high to allow sunlight to germinate the new seed If you haven’t already.
- Also, remember to double check your thatch before throwing down any seed. Thatch is a layer of living and dead grass crowns, roots, lower shoots and other organic debris at the soil surface. It can weaken and even destroy a lawn if not controlled. A thatch layer becomes a waterproof blanket on the soil surface that makes it difficult to get water, nutrients, and oxygen to the soil and to the roots of the grass. Dethatch the lawn when more than 1/2 inch of thatch develops.
- Next, aerate! It’s always more fun than it sounds …but I’m probably bias.
Back to your original question:
I’d recommend giving the seed a drink every morning before dawn and evening after dusk (provided it doesn’t go against any watering restrictions in your area): 3 min front and 4 min back at 4a AND 8p for 1 week.
Once you see some germination (hopefully after 7-10 days), then cut back to once a day watering, but start to train the grass to use less water. 5 min front and 6 min back at 3a OR 10p for 1 week.
After the grass is established and safe to walk on (or passes the “mower test”), you’ll safe to resume to normal watering times.
Hope this helps. Enjoy!
