Lawn Care & Soil Temperature Guides
Expert, science-backed guides to help you time lawn care activities using soil temperature data.
When to Aerate Your Lawn by Grass Type and Soil Temperature
Core aeration timing for cool-season and warm-season lawns. Soil temperature targets, frequency, and how aeration improves seed germination and fertilizer uptake.
lawn careCool-Season Grass Fertilization Schedule by Soil Temperature
Research-backed fertilization calendar for Kentucky bluegrass, tall fescue, and ryegrass. Use soil temperature, not the calendar, to time nitrogen, phosphorus, and potassium applications.
lawn careFall Overseeding for Cool-Season Grasses
Why fall is the best time to overseed cool-season lawns. Soil temperature targets, seed-to-soil contact, and step-by-step timing for fescue, bluegrass, and ryegrass.
lawn careFall Overseeding for Warm-Season Grasses
Should you overseed warm-season lawns in fall? When and how to overseed bermuda, zoysia, and St. Augustine with cool-season grass for winter color.
lawn careGrub Prevention Timing by Soil Temperature
When to apply grub preventers based on soil temperature and beetle life cycles. Research-backed timing for imidacloprid, chlorantraniliprole, and natural alternatives.
lawn careIrrigation Timing by Soil Temperature
How to water your lawn based on soil temperature, not the calendar. Deep vs. shallow watering, frequency adjustments for heat stress, and drought survival strategies.

Common lawn diseases and the soil temperature ranges where they thrive. Brown patch, dollar spot, Pythium blight, and snow mold: identification, prevention, and treatment.
lawn carePre-Emergent vs Post-Emergent: When to Switch
How to tell if your pre-emergent window has closed and when to switch to post-emergent herbicides. Soil temperature thresholds, product selection, and rescue strategies for late applications.
lawn careSoil Temperature and Seed Germination Rates
Exact germination timelines for common lawn grasses at different soil temperatures. Why 50°F is the threshold, how germination speed changes with warmth, and what happens when soil is too hot.
lawn careHow to Read a Soil Thermometer for Lawn Care
Step-by-step guide to measuring soil temperature correctly. Depth, timing, thermometer types, and how to use readings for seeding, pre-emergent, and fertilizer decisions.
lawn careSummer Stress Management for Lawns
How to keep your lawn alive through summer heat and drought. Soil temperature thresholds, irrigation strategies, mowing height adjustments, and when to stop fertilizing.
lawn careWarm-Season Grass Fertilization Schedule by Soil Temperature
Research-backed fertilization calendar for bermuda, zoysia, St. Augustine, and centipede. Time nitrogen applications to soil temperature and grass green-up for maximum color and density.
lawn careWhen to Stop Mowing Before Winter Dormancy
Use soil temperature to time your final mow of the season. Proper late-fall mowing height prevents snow mold, vole damage, and winterkill on cool-season and warm-season lawns.
lawn careWinter Dormancy Lawn Care: What to Do (and Not Do)
How to protect your lawn through winter dormancy. Soil temperature thresholds for dormancy, watering rules, and spring recovery preparation for cool-season and warm-season grasses.

lawn careHow to Identify and Kill Nutsedge in Your Lawn
Nutsedge is a sedge, not a grass — which is why standard weed control fails. Identify yellow vs. purple nutsedge and time herbicides by soil temperature.
