Are bugs in compost normal?

Yes! Bugs like wood roaches (palmetto bugs) and ants are common in compost piles. They help break down materials. To reduce them, keep your pile moist and add more greens.

What’s the best compost ratio for Houston yards?

Aim for 2 parts browns (dry leaves, pine needles) to 1 part greens (grass clippings, kitchen scraps, coffee grounds). This balance helps compost break down quickly.

Can I compost Bermuda grass?

Only if your compost pile reaches 140°F+. Otherwise, Bermuda runners can survive and regrow when you spread compost later.

What perennials grow best in Houston?

Texas sage, lantana, salvias, Gulf Coast muhly grass, drift roses, loropetalum, and Esperanza are consistently reliable performers in Houston's heat, humidity, and soil conditions.

When is the best time to plant perennials in Houston?

Fall and early spring are the best times to plant perennials in Houston because those seasons allow strong root development before summer heat arrives.

Do perennials survive Houston freezes?

Most Houston-friendly perennials survive freezes, but some go dormant. Avoid cutting back freeze-damaged plants until spring when new growth appears.

When should I apply pre-emergent in Houston?

Apply pre-emergent by February 1st, before soil temperatures consistently reach 55°F. That's the threshold at which warm-season weed seeds like crabgrass begin to germinate. Use a soil thermometer to confirm — once the soil hits 55°F, the window has closed.

When should I fertilize my St. Augustine lawn in Houston?

When the lawn tells you it's ready — not when the calendar does. Watch for nighttime temperatures above 55°F for at least 5 consecutive days and your grass actively greening with new growth. In Houston this typically happens between late March and early May, but it varies year to year.

When should I fertilize Bermuda grass in Houston?

When it's fully green and you've mowed it at least twice. Bermuda wakes up later than St. Augustine — usually late April or May in Houston, but a cold spring can push it later.

Do I need to add a surfactant to my weed killer?

Yes — always. A non-ionic surfactant helps herbicide spray stick to the waxy surface of weed leaves and penetrate the plant. Without it, much of your spray runs off and loses effectiveness.

Should I get a soil test for my Houston lawn?

Yes — especially if you've been fertilizing and still not seeing results. Houston clay varies yard to yard. A Texas A&M soil test tells you exactly what's missing before you spend more money on product.
