Pennsylvania Lawn Calendar
What your Kentucky Bluegrass lawn needs, season by season.
Spring
- Pre-emergent by mid-April (southeast) — redbud bloom is a good signal
- Lime per soil test as soon as ground firms up
- Red thread flares in cool wet May — a light nitrogen feeding usually outgrows it
- Mow at 3 inches, never removing more than a third
Summer
- Grub preventive down by late June
- Raise mowing to 3.5–4 inches for July heat
- Water 1 inch/week or accept summer dormancy
- Scout sunny dry banks for chinch bug damage
Fall
- Seed and overseed mid-August to late September
- Fertilize September and late October — before the Dec 15 legal cutoff
- October broadleaf application for dandelion, violet and ground ivy
- Final mow short; rake leaves to prevent snow mold mats
Winter
- No fertilizer Dec 15 – Mar 1 (state law)
- Keep plow piles and salt off turf edges
- Watch for vole runways under melting snow
- Soil test and plan lime for early spring
