Renovating a Weedy, Drought-Damaged Lawn: Soil Building, Crabgrass Control, and Fall Seeding

Provo, Utah's three-year drought left your lawn sparse, brown, and overrun with crabgrass. Reseeding now (summer) will fail. The smart play: spend summer building soil, then seed in fall.

Summer Soil-Building Plan

1. Get a soil test from Utah State University Extension (extension.usu.edu). It's cheap and essential.
2. Suppress crabgrass by preventing seed set. Crabgrass is an annual—it dies at frost. Mow frequently or hand-pull before it seeds. Do not let it go to seed.
3. Plant a summer cover crop. Alfalfa, hairy vetch, or buckwheat smother weeds, fix nitrogen (legumes), and add organic matter when turned under.
4. Topdress with compost to improve water retention and microbial life.

Fall Seeding

Early September: prepare seedbed, sow a drought-tolerant mix (tall fescue + Kentucky bluegrass for Utah), keep moist, and follow soil test recommendations. Your new lawn will establish deep roots before winter.

Patience now pays off with a resilient, weed-resistant lawn for years.
