Lawn care tips for Longmont's dry, alkaline soil
That alkaline pH (around 7.7) can lock up iron and make grass look pale even when you're doing everything right. Deep, infrequent watering beats daily sprinkles every time. One common mistake? Overwatering to compensate for dry spells, which just invites fungus. Check out our lawn guides for more on reading your yard's signals.

We are very happy Sunday customers in our second year of Lawn Care Program. After a rough winter we decided to over-seed using your Fescue Mix. Bare patches gone, lawn is much healthier. Easy to use, our cat's much happier with your products. Of course, 12 inches of Spring rain didn't hurt either.

Colorado Lawn Transformation
Sunday was a game changing experience for my lawn. Even though lawn care is a seasonal tasks in Colorado it can still be a challenge with frequent changes in temperature and moisture on an annual basis. My yard was very patchy and overrun by weeds when we moved in back in 2017. I found Sunday in the Spring of 2019 after searching for fertilizer safe for my pets. The yard has transformed over the past two years and continues to improve with each application. I appreciate the excellent customer experience as well whenever I have a question or concern.

Longmont, Colorado FAQs
How to grow grass in Longmont, Colorado
| Recommended grass species | Kentucky bluegrass, perennial ryegrass, tall fescue, fine fescue |
| Best establishment method | Seeding |
| Spring seeding window | May 15 to June 5 |
| Fall seeding window | September 19 to October 10 |
Growing grass in Longmont means working with alkaline soil, dry conditions, and a tight window for success. Cool-season grasses like Kentucky bluegrass and tall fescue thrive here, but timing matters more than most places.
Seed smart before the Colorado summer hits
Your best shot at establishment is mid-May through early June or mid-September into October. Skip July and August entirely (your seeds will just sit there, judging you). Before planting, test your soil pH and consider amendments for that alkaline lean. Find premium grass seed suited to semiarid climates, or let us help you find the right grass for my yard. One common mistake? Overwatering new seed instead of frequent, light watering.
