Spring in Texas isn’t like spring up north. By mid-March, soil temperatures are already climbing, warm-season grasses are waking up, and the window for early-spring tasks is closing fast. Miss it, and you’ll be fighting against drought stress and summer weeds all season long.

If you’re in Texas, here’s what you need to know to nail the spring transition.

Read Your Soil Temperature

Forget the calendar. In Texas, grass care timing is all about soil temperature.

Warm-season grasses—Bermuda, zoysia, and buffalograss—start actively growing when soil temps hit 60°F. That’s your cue to switch gears from dormancy management to growth support.

By mid-March in most of Texas, you’re already there. Soil temps are hitting 60-65°F in Central Texas and creeping above that in South Texas. North Texas is a bit behind, but catching up fast.

Check your soil temperature before making any big decisions. A simple soil thermometer costs under $15 and saves guesswork. Stick it 4 inches into the ground in the morning. If you see 55°F or higher, your grass is ready for active care.

Aerate Now if You’re Going to Aerate

This is the last good window. Aeration in Texas should happen in early spring—right when grass is starting to green up but before peak growth takes over. That’s roughly late February through mid-March for most of the state.

Why now? Aeration creates stress on the plant, and it’s easiest to recover when there’s still moderate temperatures and spring rain (if you’re lucky). Hit aeration in summer heat, and you’ll weaken your lawn right when it needs strength most.

If your lawn is compacted or hasn’t been aerated in 3+ years, this is your move. Rent a core aerator for $40-60, or hire a pro for $200-400. Either way, you’ll improve drainage, reduce thatch, and give roots more breathing room—which translates to better drought tolerance in July and August.

Follow up with a light dressing of compost if you have it. The seed-to-soil contact from aeration makes a difference.

Pre-Emergent: Catch Crabgrass Before It Starts

Crabgrass is the Texas summer weed. It germinates when soil temps hit 55°F—which means by mid-March, you’re at or past the ideal window for pre-emergent application.

If you haven’t applied pre-emergent yet, do it this week. A few more warm days and you’ll miss the window entirely. Once crabgrass is up and growing (usually early April in Texas), pre-emergent won’t touch it.

Your options:

  • Synthetic pre-emergent (pendimethalin, dithiopyr): Fast, reliable, widely available. Apply as soon as possible. Most products break down in 6-8 weeks, so timing matters.
  • Corn gluten meal: Organic, safe, but less potent and needs earlier application (late February ideal). If you’re considering it, you’re probably already late for this year.

Apply on a day when the lawn is dry, water it in lightly, and avoid new seeding for a few weeks (pre-emergents will block your seed too).

Fertilize to Support Green-Up

Once soil temps are consistently above 60°F, your warm-season grass is hungry. Spring growth requires nitrogen and phosphorus.

Use a balanced or slightly higher-nitrogen formula. Something like 10-5-5 or 12-4-8 works well. Avoid anything with weed killer (that’s for fall); you just want to feed the grass.

Apply about 0.5-1 lb of actual nitrogen per 1,000 sq ft. That translates to:

  • 5 lbs of 10-5-5 per 1,000 sq ft, or
  • 8-10 lbs of 12-4-8 per 1,000 sq ft

Water it in lightly. Spring rain will do most of the work, but if you’ve got dry conditions, a half-inch of water after application helps dissolve the nutrients and carry them into the soil.

Plan for a second spring feeding in mid-May, then switch to summer maintenance rates (lighter feeding, more focus on stress tolerance).

Mow at the Right Height

As your grass starts to grow, mowing height matters. Warm-season grasses are toughest when mowed at the right height for their species:

  • Bermuda: 0.75–1.5 inches (lower for golf course quality, higher for relaxed lawns)
  • Zoysia: 1–2 inches
  • Buffalograss: 2–3 inches

Keep your mower blade sharp. A dull blade tears grass, stressing it out and making it vulnerable to disease and drought. Sharp mower = clean cut = faster recovery = happier lawn.

Mow once a week during active growth. If the lawn grows more than 1/3 of its blade height in a week, bump mowing to every 5 days.

Don’t Overwater

This is the biggest mistake Texas homeowners make in spring. Cool-season rain feels generous, but warm-season grass doesn’t need daily watering yet.

Soak less frequently, but soak deeply. Aim for 1 inch of water per week (from rain or irrigation combined). Apply it in one or two sessions, not daily sprinkles.

Deep, infrequent watering encourages roots to grow deeper, which builds drought tolerance for summer. Daily watering keeps roots shallow and weak—exactly what you don’t want heading into July.

Spot-Treat Emerging Weeds

By mid-March, broadleaf weeds (clover, dandelions, chickweed) are popping up. Don’t let them establish. Spot-treat with a post-emergent herbicide designed for warm-season grass, or dig them out by hand.

Manual removal is underrated. Grab a dandelion digger or a knife, dig down below the tap root, and pull. It’s fast, chemical-free, and teaches you what your problem weeds look like before they spread.

One warning: avoid blanket herbicide sprays right now. Warm-season grass is just waking up and is sensitive to stress. Spot-treating is safer and more effective anyway.

Your Texas Spring Action Plan

  1. Check soil temperature this week → If it’s above 55°F, you’re in active season.
  2. Apply pre-emergent immediately → Don’t wait another week.
  3. Aerate if needed → Last call for spring aeration.
  4. Fertilize with a balanced formula → Feed the green-up.
  5. Mow sharp → Keep the blade fresh and height consistent.
  6. Water deep, not often → 1 inch per week total.
  7. Spot-treat weeds → Keep them small before they spread.

Get these right, and your Texas lawn will head into summer strong—healthier, thicker, and ready to handle the heat and drought that follow.

The spring transition is short but crucial. Don’t sleep on it.
