When does pre-emergent application typically open in Friendswood, TX?

Pre-emergent application typically opens in April to May for Friendswood, TX, 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 Friendswood, TX?

Friendswood, TX is a transition zone where both cool-season and warm-season grasses are common. Cool-season grasses (tall fescue, Kentucky bluegrass, perennial ryegrass, fine fescue) thrive when 2-inch soil sits in the 50–65°F range and slow down in midsummer heat. 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 Friendswood, TX?

In Friendswood, TX, the first fall frost typically arrives around December 27. 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?

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

Cool-season grasses like fescue, Kentucky bluegrass, and perennial ryegrass germinate best when 2-inch soil temperature sits in the 50–65°F range for several consecutive days. Above that, summer heat stresses young seedlings; below that, germination slows or stalls. 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.
