Crabgrass Preventer Timing: Soil Temperature Trumps Calendar

Apply pre-emergent when soil hits 50°F consistently (often coinciding with forsythia or crocus bloom). Expect ~6 weeks control; heat and rain shorten it. Water after application to move chemical into the germination zone. If dry, irrigate to trigger weed germination so the chemical kills emerging roots.

Buffalo Grass Seeding Note

Buffalo grass establishes best in late spring/early summer, not fall. If summer seeding failed, re-seed in May-June when soil is warm.
