When does pre-emergent application typically open in Yuma, AZ?

Pre-emergent application typically opens in April to May for Yuma, AZ, when 2-inch soil temperature reaches the 50–55°F threshold for several consecutive days. Apply earlier than that and the herbicide degrades before crabgrass germinates; apply later and weeds have already sprouted. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

What grass types grow best in Yuma, AZ?

Yuma, AZ is primarily a warm-season climate. Warm-season grasses (Bermuda, Zoysia, St. Augustine, Centipede, Bahia) thrive once 2-inch soil sits in the 65–90°F range and go dormant brown over winter. Picking a grass family that matches the climate is the single biggest lawn-care decision; transition-zone homeowners often maintain blends and accept that neither family will look perfect year-round. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

When is the first fall frost typically expected in Yuma, AZ?

In Yuma, AZ, the first fall frost typically arrives around December 28. Soil temperature continues to drop through October and November, which closes the fall fertilizer window for warm-season grasses and opens the dormant-seeding window for cool-season grasses. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

How often is this schedule updated?

Recommendations recompute every 6 hours from the latest reading at Yuma 27 ENE, about 28 miles from Yuma. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.

What soil temperature do warm-season grasses need to germinate?

Seeded warm-season grasses like Bermuda and Zoysia germinate best when 2-inch soil temperature sits in the 65–90°F range for several consecutive days; below that range, seed sits dormant or rots. St. Augustine establishes from sod or plugs rather than seed, but takes hold in the same warm-soil window. The re-entry interval (REI) on any post-emergent products you apply during establishment is on the product label; respect it before letting pets or children back on treated areas. This is informational guidance only, not a prescription. The label is the law. Consult your local Cooperative Extension office before applying any product.
