Nome Lawn Care Calendar
Round 1 — Early Spring Pre-Emergent
Soil temp reaches 55°F- Pre-Emergent Herbicide — Apply a pre-emergent herbicide (Prodiamine or Dithiopyr) to prevent crabgrass and other annual weeds as soil warms past 55°F. Do NOT apply if you plan to seed within 8-12 weeks.
Round 2 — Mid Spring
Soil temp reaches 65°F- Pre-Emergent (2nd Application) — Second split-app of pre-emergent as soil approaches 65°F. Extends crabgrass prevention through early summer.
- High-Nitrogen Fertilizer — First fertilizer of the season. Apply high-nitrogen to support spring green-up now that the grass is actively growing.
- Bio-Stimulant(optional) — Bio-stimulant (humic/fulvic acid, sea kelp) for root development and nutrient uptake.
Round 3 — Late Spring
28-35 days after previous round- Low-N / High-K Stress Fertilizer — Transition to a low-nitrogen, high-potassium fertilizer to harden turf for summer heat.
- Grub Preventative — Apply a preventative grub control (e.g. GrubEx / chlorantraniliprole) before grubs hatch. Best applied late spring when soil temps reach 60-70°F.
- Post-Emergent Broadleaf Herbicide(optional) — Spot-treat or blanket-spray broadleaf weeds (dandelions, clover, plantain) while they are actively growing in spring.
- Bio-Stimulant(optional) — Bio-stimulant to support root depth and stress tolerance.
- Moisture Manager(optional) — Optional wetting agent / moisture manager to improve water penetration.
Round 4 — Summer
28-42 days after previous round- Low-N / High-K Stress Fertilizer(optional) — Continue stress-blend fertilizer through the summer heat period.
- Surface Insect Control(optional) — Apply a surface insecticide (e.g. bifenthrin) to control armyworms, chinch bugs, sod webworms, and other surface-feeding pests.
- Bio-Stimulant(optional) — Bio-stimulant to maintain soil biology through heat stress.
Round 5 — Fall Renovation (Seeding)
Soil temp drops to 70°F- Starter Fertilizer — Apply a high-phosphorus starter fertilizer to support new seed establishment.
- Seed-Safe Pre-Emergent — Apply a seed-safe pre-emergent (e.g. mesotrione/tenacity) for weed suppression that won't harm new seedlings.
- Aerate & Overseed — Core aerate the lawn, then overseed with your chosen grass seed blend.
- Bio-Stimulant(optional) — Bio-stimulant to accelerate seed germination and root establishment.
Round 5 — Fall Recovery
Soil temp drops to 70°F- High-Nitrogen Fertilizer — Apply high-nitrogen fertilizer to promote fall recovery and thickening.
- Pre-Emergent (Fall) — Fall pre-emergent to prevent poa annua and other winter annual weeds.
- Post-Emergent Broadleaf Herbicide(optional) — Fall is the most effective time for broadleaf weed control. Spray weeds while they are pulling nutrients down to roots before winter.
- Bio-Stimulant(optional) — Bio-stimulant to support root growth during fall recovery.
Round 6 — Mid Fall
28-35 days after previous round- High-Nitrogen Fertilizer — High-nitrogen feed to maximize fall growth and carbohydrate storage.
- Bio-Stimulant(optional) — Bio-stimulant to support late-season root development.
Round 7 — Winterizer
Soil temp drops to 35-40°F- Winterizer Fertilizer — Final application of high-nitrogen + potassium fertilizer before dormancy to build winter hardiness and promote early spring green-up.
