The PA Spring Lawn Treatment Schedule (Month-by-Month)
Pre-emergent, fertilizer, weed control, and seeding — when each step needs to happen in Carbon County.
The 2026 Carbon County spring schedule
Climate matters more than the calendar, but here's the rough month-by-month plan that works for most Lehighton-area lawns.
March (early)
- •Spring cleanup. Rake out matted leaves, debris, sticks. Edge the beds.
- •Soil test (optional). $15 at the Penn State Extension office. Tells you exactly what your lawn needs.
March (late) – Early April
- •Pre-emergent crabgrass control. Critical timing — must go down before forsythia blooms drop. Miss this window and you're fighting crabgrass all summer.
- •Mower tune-up. Sharp blades, fresh oil.
Mid-April
- •First mow at 3″ – 3.5″.
- •Spring fertilizer (slow-release, light application).
Late April – May
- •Mulch installs. Best time of year — soil is workable, weeds haven't taken over.
- •Spot weed control for any breakthroughs.
May
- •Aeration if you missed fall. Pair with overseeding.
- •Adjust mowing height up to 3.5″ – 4″ as temps climb.
Late May – June
- •Second fertilizer round (lighter — don't push growth in heat).
- •Watch for grub damage — patches that pull up like carpet.
Don't DIY this if...
You're not sure on timing, you have pets/kids and don't want to handle granular chemicals, or your lawn is in rough shape and you want it fixed right.
