A Proven Lawn Care Schedule for a Greener Lawn in 2026

A Proven Lawn Care Schedule for a Greener Lawn, By Rob Haneisen

While Landscape Systems Garden Center is not in the business of lawn care, we recognize that a healthy lawn is an important factor in maintaining a beautiful landscape. Our resident horticulturist, Rob Haneisen, has offered his expertise – just in the nick of time. Read on and act now to prepare your lawn for spring!

What is Pre-Emergent and What Does it do For Your Lawn? 

Here’s a surprising truth:

Pre-emergent does NOT kill existing weeds.

Instead, pre-emergent works by preventing weed seeds from taking root in your lawn. During winter, early spring, and fall, thousands of weed seeds travel through the air and settle into your lawn. Once temperatures warm up and days get longer, those seeds germinate and establish themselves in your lawn – unless you stop them first. That’s where pre-emergent treatments come in.

Pre-emergent creates a protective barrier in the soil that stops those seeds before they ever become visible weeds. As the primary root emerges from the seed, it comes into contact with this protective barrier and dies.

Pre-emergent does not disrupt germination but must be applied to your lawn before germination begins. 

When Should I Apply Pre-Emergent in North Texas?

Timing is everything. In the DFW area, there are two critical application windows:

Spring Application – No later than February 15 – 20

This application targets weeds that germinate as soil temperatures warm in early spring. Waiting too long allows seeds to sprout—and once they do, pre-emergent won’t help.

Fall Application – No later than October 1

After months of seeds blowing around in the summer wind, many weeds begin germinating again in fall. Applying pre-emergent by October 1 helps prevent winter weeds from taking over your lawn.

A Proven Lawn Care Schedule for a Greener Lawn

Rob says (promises, actually) that if you follow this simple seasonal formula, you’ll set your lawn up for success all year long.

✅ By February 15

• Apply pre-emergent

✅ By April 1 – First Feeding

• Fertilizer with N-P-K 20-5-5

• Supports strong top growth and early green-up

✅ By June 1 – Optional Second Feeding

If your grass looks tired or faded:

• Repeat 20-5-5, or

• Apply aluminum sulfate for a fast green-up and nutrient boost

Ever wonder why golf course fairways stay so green in summer?

Aluminum sulfate plays a big role. (Yes—even if some greens are also painted!)

✅ After September 21

• If you skipped the June feeding, apply 20-5-5 again

✅ October 1

• Apply pre-emergent for winter weeds

✅ Final Fall Feeding

• Fertilizer with N-P-K 5-5-15

• High potassium (K) strengthens roots and prepares your lawn for winter dormancy

How Much Should I Water my North Texas Lawn?

Watering correctly is just as important as fertilizing.

• Lawns need only ½ inch of water per week

• Water 2–3 times per week, not daily

• Never water at night (this encourages disease)

• Water in the early morning instead

If you’re currently splitting watering time between morning and evening (for example, 20 minutes AM + 20 minutes PM), move it all to the morning – but only about 30 minutes total per station.

The Bottom Line

If you observe Rob’s recommended schedule and

• Apply pre-emergent on time

• Feed your lawn seasonally

• Water correctly

You will have a greener, healthier North Texas lawn in 2026!
