Spring in The Woodlands doesn't arrive on a calendar date. One week brings 80-degree afternoons, the next drops back to the 50s with rain. Your lawn wakes up gradually, and knowing when to make that first cut makes a real difference in how your grass performs all season.
Wait for Active Growth, Not a Date
The urge to mow hits when you see green returning, but cutting dormant or barely-active grass stresses it. St. Augustine typically breaks dormancy when soil temperatures stay consistently above 65 degrees, usually late March through early April here. Bermuda needs slightly warmer soil, often mid to late April.
The best signal is growth itself. When your grass grows enough that it needs cutting, it's ready. If you're walking across the lawn and it still crunches underfoot or looks thin and pale, wait another week. Once you see genuine green-up and the grass reaches about a third taller than your target mowing height, you're good to go.
Set Your Mower Higher Than Summer Height
That first spring cut should be higher than you'll mow in summer. For St. Augustine, start at 3.5 to 4 inches. For Bermuda, 2 to 2.5 inches works well. Higher cutting encourages deeper roots, which your grass needs as it comes out of dormancy and prepares for our hot months ahead.
Never remove more than one-third of the blade height in a single mowing. If your lawn got shaggy over winter or you waited a bit long, make two passes a few days apart rather than scalping it all at once. Scalping in early spring exposes tender new growth to late cold snaps and invites weeds into bare spots.
Check Your Equipment First
Before that first cut, sharpen your mower blade. Dull blades tear grass instead of cutting it cleanly, leaving ragged brown tips that invite disease. Spring is also when brown patch and take-all root rot start showing up in our area, and a clean cut helps grass resist infection.
Make sure your mower deck is clean and your tire pressure is even so you get a level cut. Uneven mowing stresses grass and creates low spots where water pools, which becomes a problem fast in our clay soil.
Adjust Your Schedule as Growth Picks Up
Early spring might mean mowing every 10 to 14 days. By late April and May, when temperatures climb and we get regular rain, you could be mowing weekly. St. Augustine especially grows fast once it really wakes up.
Pay attention to your grass, not the calendar. Some springs stay cool and dry, others turn warm and wet early. Your lawn will tell you what it needs. If you're only taking off a tiny bit of blade, you can stretch it another few days. If you're bagging heavy clippings, you waited too long.
Don't Bag Those Early Clippings
As long as you're following the one-third rule, let those clippings fall. They return nitrogen and organic matter to the soil, which helps your grass green up faster. Our clay soil here benefits from any organic material it can get.
The exception is if your lawn has heavy thatch buildup or you're dealing with a fungal issue. In those cases, bagging for a few weeks makes sense until things improve.
