Kansas Lawn Care Calendar
Cool-Season Program
Round 1 — Early Spring Pre-Emergent
When soil temperature 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
When soil temperature 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)
When soil temperature 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
When soil temperature 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
When soil temperature 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.
Warm-Season Program
Round 1 — Early Spring Pre-Emergent
When soil temperature reaches 55°F- Pre-Emergent Herbicide — Apply pre-emergent herbicide before soil reaches 55°F to prevent summer annual weeds.
Round 2 — Spring Green-Up
When soil temperature reaches 65°F- Low-N / High-K Stress Fertilizer — Apply a low-nitrogen, high-potassium fertilizer as warm-season turf exits dormancy.
- Pre-Emergent (2nd Application) — Second split-app of pre-emergent for extended weed prevention.
- Bio-Stimulant(optional) — Bio-stimulant to jumpstart soil biology as soil temps rise.
Round 3 — Early Summer
28-42 days after previous round- High-Nitrogen Fertilizer — Apply high-nitrogen fertilizer during peak warm-season growth.
- Grub Preventative — Apply preventative grub control (e.g. GrubEx / chlorantraniliprole) before grubs hatch. Critical for warm-season lawns where grubs can cause severe damage.
- Post-Emergent Broadleaf Herbicide(optional) — Spot-treat or blanket-spray broadleaf weeds while they are actively growing. Use warm-season safe formulations (avoid 2,4-D on St. Augustine).
- Bio-Stimulant(optional) — Bio-stimulant for root depth and nutrient uptake.
- Moisture Manager(optional) — Optional wetting agent to improve water distribution during heat.
Round 4 — Mid Summer
28-42 days after previous round- High-Nitrogen Fertilizer — Continue high-nitrogen feeding during warm-season peak growth.
- 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 for sustained soil health.
Round 5 — Late Summer
28-42 days after previous round- High-Nitrogen Fertilizer — Final high-nitrogen application before growth slows in fall.
- Surface Insect Control(optional) — Monitor for late-season armyworm and chinch bug activity. Apply surface insecticide if damage is present.
- Bio-Stimulant(optional) — Bio-stimulant to prepare turf for seasonal transition.
Round 6 — Fall Transition
When soil temperature drops to 70°F- Low-N / High-K Stress Fertilizer — Switch to low-nitrogen, high-potassium to harden turf for winter dormancy.
- Pre-Emergent (Fall) — Fall pre-emergent to prevent cool-season annual weeds (poa annua).
- Post-Emergent Broadleaf Herbicide(optional) — Fall is an effective time for broadleaf weed control in warm-season lawns. Target weeds as they prepare for winter.
- Bio-Stimulant(optional) — Bio-stimulant to support root carbohydrate storage.
Round 7 — Late Fall / Dormancy
When soil temperature drops to 55°F- Bio-Stimulant(optional) — Light bio-stimulant application to maintain soil biology through winter dormancy. No nitrogen fertilizer needed.

Frequently Asked Questions
When should I start fertilizing my lawn in Kansas?
In Kansas, the best time to start fertilizing depends on your grass type. For transition zone lawns, timing depends on your grass type — cool-season grasses start at 55°F soil temp, while warm-season grasses wait until 65°F. Use a soil thermometer for accurate timing rather than relying on calendar dates alone.
What is the best grass type for Kansas?
Kansas is in the transition zone zone, so the best grass types include both cool-season grasses like Tall Fescue and warm-season options like Bermuda and Zoysia. The ideal choice depends on your specific USDA zone, sun exposure, and maintenance preferences.
How often should I mow my lawn in Kansas?
Mowing frequency in Kansas varies by season. During peak growing season, mow every 5-7 days during your grass type's active growing period. Always follow the one-third rule — never remove more than one-third of the blade height in a single mowing.
