Spring 2026 Lawn Maintenance: Your Month-by-Month Playbook

Spring 2026 is shaping up to be a wet, mild start across most of North America, which means lawns will green up early — and weeds will too. Get ahead of both with this month-by-month plan you can actually keep up with on weekends.

Why Spring Sets the Tone for the Whole Year

Whatever you do (or skip) in March, April, and May determines how your lawn handles the summer heat. Strong, deep roots built in spring are what keep grass alive in July. Skip the early work and you''re patching brown spots all summer.

March: Wake It Up

Wait until the soil is no longer soggy underfoot — walking on saturated grass compacts it.

• Rake out the thatch. A light dethatching with a spring-tine rake clears matted dead grass and leaf debris so sunlight and air reach the crown.
• Inspect for damage. Voles, snow mold, and salt spray near walkways all show up now. Loosen matted patches and reseed bare spots once daytime temps stay above 50°F (10°C).
• Sharpen the mower blade before its first use. A dull blade tears grass tips, leaving them brown and disease-prone.
• Service the mower: fresh oil, new spark plug, and clean the deck. Five minutes now beats a midseason breakdown.

Early April: Pre-Emergent and First Mow

This is the single most important window of the spring.

• Apply pre-emergent herbicide when soil temperatures hit a sustained 55°F (13°C) — typically right around forsythia bloom. This stops crabgrass before it germinates. Miss this window and you''re fighting it all summer.
• First mow: cut high. Set your deck to 3–3.5 inches and only remove the top third of the blade. Tall grass shades out weeds and grows deeper roots.
• Soil test if you haven''t in three years. A $15 kit will tell you exactly what your lawn needs instead of guessing.

Late April: Feed and Overseed

• First feeding: a slow-release nitrogen fertilizer (look for an NPK around 20-0-5 if your phosphorus is already adequate). Apply to dry grass, then water it in.
• Overseed thin areas with a grass type that matches your existing lawn. Keep the seed bed moist with light daily watering until germination.
• Edge beds and walkways. Crisp edges make the whole lawn look professionally maintained, even if it''s not perfect everywhere else.

May: Build Resilience

By now the lawn is actively growing and will need mowing weekly — sometimes twice.

• Mow on the "one-third rule": never remove more than a third of the blade in a single cut. If it got away from you, mow high first, then cut again 2–3 days later.
• Leave the clippings. They return up to 25% of the nitrogen your lawn needs and don''t cause thatch (that''s a myth).
• Watch for grubs. If you had grub damage last year, late May is the window for preventive treatment.
• Start watering deeply, infrequently. One inch per week, ideally in one or two sessions, drives roots down. Daily light watering keeps roots shallow and weak.

Tools Worth Owning

You don''t need a shed full of equipment, but a few things pay for themselves quickly:

• A spring-tine rake for dethatching
• A broadcast spreader (push, not handheld) for even fertilizer coverage
• A soil moisture meter or just a long screwdriver — if it pushes in 6 inches easily, the soil is moist enough
• A blade sharpener or a spare pre-sharpened blade
