2026 Lawn & Pest Plan

1

Pre-Emergent + Spring Fertilizer

🗓 Late March – Mid April · ⏱ ~30 min

Why this matters

This is the single most important application of the year. Pre-emergent herbicide creates a chemical barrier in the soil that prevents crabgrass and other annual weeds from germinating. Once crabgrass sprouts, it's 10x harder to deal with. The fertilizer portion gives your fescue/bluegrass a gentle push out of winter dormancy without overstimulating top growth. Timing is everything — you want this down before soil temps hit 55°F consistently, which in Louisville is typically early-to-mid April.

🧪

Scotts Turf Builder Halts Crabgrass Preventer with Lawn Food

Covers 5,000 sq ft (you'll have leftovers for next year). Combo product — pre-emergent + fertilizer in one pass.

~$28 at Lowe's / Home Depot

How to apply

1

Mow your lawn to about 3 inches if it's gotten shaggy over winter. Bag the clippings this one time so the granules reach the soil.

2

Load granules into a broadcast spreader (a cheap $25 push spreader works fine — you'll use it all year). Set the dial to the setting listed on the bag for your spreader model.

3

Walk at a steady pace, slightly overlapping each pass. Cover the whole lawn in one direction. For better coverage, do a second pass perpendicular to the first using half the dial setting.

4

That's it. Rain will activate it naturally — no need to water. If there's no rain for 3+ days, a quick pass with a hose helps but isn't critical.

💡 Tip: Don't apply this if you plan to seed bare spots in spring. Pre-emergent prevents ALL seeds from germinating, including grass seed. For spring bare spots, just scratch in some seed by hand and skip those areas with the spreader. The big overseed push is in September anyway.

2

Weed Control + Spring Feed

🗓 Mid May – Early June · ⏱ ~25 min

Why this matters

By mid-May, any broadleaf weeds that slipped past the pre-emergent (dandelions, clover, chickweed) are actively growing and vulnerable to post-emergent herbicide. The weeds are young and actively absorbing nutrients, so they take up the herbicide easily. The fertilizer portion feeds your lawn during its peak spring growth period before summer heat arrives.

🧪

Scotts Turf Builder Weed & Feed (Step 2) — or store brand

5,000 sq ft bag. Kills dandelions, clover, and other broadleaf weeds while feeding your lawn. Apply when weeds are actively growing and visible.

~$28 at Lowe's / Home Depot

How to apply

1

Apply in the morning when dew is still on the grass, OR lightly wet the lawn with a hose first. The granules need to stick to weed leaves to work — dry leaves = wasted product.

2

Load the spreader and walk at a steady pace. One direction is fine for this one.

3

Do NOT mow for 2-3 days after applying. You want the herbicide absorbed through the weed leaves, not chopped off. Also don't water for 24 hours.

💡 Tip: If you only have a few dandelions, skip the full weed & feed and just use a $5 bottle of Ortho Weed-B-Gon spot spray. Then use a straight fertilizer instead (Scotts Turf Builder Lawn Food). Cheaper and less herbicide overall.

3

Preventive Grub Control

🗓 June 1 – June 15 · ⏱ ~15 min

Why this matters

Japanese beetle and June bug grubs feed on grass roots from late summer through fall. By the time you see spongy brown patches you can peel up like carpet, the damage is done. A preventive product applied in early June kills grubs shortly after they hatch, before they can cause damage. This is especially important because you're not watering — a lawn under drought stress that also has grub damage will look terrible by September.

🪲

Scotts GrubEx (or BioAdvanced Season Long Grub Control)

Covers 5,000 sq ft. One application protects all season. Must be applied BEFORE grub damage appears.

~$22–28

How to apply

1

Mow first if needed (no special height required).

2

Load the spreader and apply evenly across the entire lawn. Same walking pattern as before.

3

This one actually does need watering in — the product needs to reach the soil where grubs live. If rain isn't forecast within 2-3 days, give the lawn a good soak with a hose. A single thorough watering is all it takes.

💡 Tip: Time this with a rain forecast if possible and you won't have to water at all. Check your weather app and spread it the day before rain.

4

Fall Fertilizer + Overseed Bare Spots

🗓 Sep 1 – Sep 20 · ⏱ ~45 min

Why this matters

This is the most productive application of the year for cool-season grass. Louisville's September weather — warm days, cool nights, decent rainfall — creates ideal growing conditions. Your fescue and bluegrass are entering their strongest growth phase. Fertilizing now promotes deep root development that helps the lawn survive next summer's heat even without irrigation. And this is THE window to fix bare spots — fall overseeding success rates are dramatically higher than spring.

🌱

Scotts Turf Builder Lawn Food (32-0-4 or similar fall formula)

5,000 sq ft bag. Just fertilizer — no herbicide (you don't want weed killer when you're seeding).

~$22–25

🌾

Tall Fescue Blend Grass Seed (3–5 lb bag)

Look for a "turf type" tall fescue blend. Pennington Smart Seed or Scotts ThickR Lawn both work. Only needed for bare/thin spots.

~$12–18

How to apply

1

Mow a bit shorter than usual (2.5–3 inches) and bag the clippings. This lets sunlight reach the soil where you're seeding.

2

For bare spots: rake the area lightly to rough up the soil surface. Scatter seed by hand at a fairly heavy rate. Gently tamp it down with your foot or the back of a rake. Seed needs soil contact to germinate.

3

Spread the fertilizer with your spreader across the entire lawn, including seeded areas.

4

If it doesn't rain within a few days, hose down the seeded patches to keep them moist. New seed needs consistent moisture for 2–3 weeks to germinate. Even with a no-watering philosophy, this is the one time a little hose work pays off big.

💡 Tip: Toss a thin layer of straw or peat moss over seeded bare spots. It holds moisture, prevents birds from eating the seed, and keeps the soil from crusting over. A $5 bale of straw goes a long way on a small yard.

5

Winterizer Fertilizer

🗓 Late Oct – Mid Nov · ⏱ ~20 min

Why this matters

The last fertilizer of the year helps your lawn store energy in its root system over winter. High potassium content strengthens cell walls and improves cold tolerance. The payoff comes in spring — lawns that get a late fall feed green up noticeably faster and thicker the following March. Apply at least 6 weeks before the ground typically freezes (Louisville's first hard frost averages late October/early November).

❄️

Scotts Turf Builder WinterGuard Fall Lawn Food

5,000 sq ft bag. High-potassium formula for late-season root building. Make sure the bag says "WinterGuard" or "Winterizer" — this is different from the September feed.

~$22–25

How to apply

1

Mow one last time if the grass is still growing — it may still be 3+ inches in late October. You can mulch-mow fallen leaves at the same time (free fertilizer).

2

Spread with your spreader at the bag's recommended rate. Walk the yard just like every other time.

3

Clean and store your spreader for the season. Give it a quick rinse — fertilizer residue corrodes metal parts over winter.

💡 Tip: Mulch your leaves instead of raking. Run the mower over them until the pieces are small enough to fall between the grass blades. Leaf mulch breaks down over winter and returns nutrients to the soil. Only rake/bag if the leaf layer is so thick it's smothering the grass.

6

Perimeter Pest & Spider Control

🗓 Quarterly: Mar, Jun, Sep, Dec · ⏱ ~20 min each

Why this matters

Spiders, ants, centipedes, earwigs, and other creepy-crawlies get into your house through gaps around the foundation, doors, windows, and where pipes/wires enter. A perimeter spray creates a chemical barrier that kills bugs on contact and repels them for weeks. Indoor application on baseboards lasts up to 12 months on non-porous surfaces. Outdoor treatment needs refreshing every 3 months since rain and UV break it down. This is separate from your lawn care but arguably the application you'll appreciate most day-to-day.

🕷️

Ortho Home Defense Insect Killer for Indoor & Perimeter

1.1 gal jug with comfort wand sprayer. Kills spiders, ants, roaches, earwigs, centipedes, silverfish, and more. One jug lasts 2–3 quarterly outdoor applications plus one thorough indoor treatment.

~$18–22 (1.1 gal with wand)

Outdoor perimeter

1

Choose a dry day with no rain in the next 24 hours. Clear debris, leaves, or mulch away from the foundation.

2

Spray a 12-inch wide band along your entire home's foundation. Also spray around all exterior doors, windows, garage doors, and where pipes/wires enter the house.

3

Hit any cracks, crevices, or gaps in the foundation. Pay extra attention to basement window wells — spider highway.

Indoor (1–2x per year)

1

Spray a 4-inch band along baseboards in the basement, garage, and any rooms where you see bugs. Focus on corners and behind appliances.

2

Spray around interior door frames, window frames, and where pipes come through walls (under sinks, behind toilets).

3

Let it dry completely (15–20 min) before people/pets walk on treated surfaces. No fumes, dries clear.

💡 Tip: Do the first outdoor application in March before bugs get active, then refresh every 3 months. One thorough indoor application in spring usually lasts most of the year. If you see a spider resurgence in fall, do a quick interior touch-up.
