No guessing. No generic calendar. LawnFlex watches soil temps and local weather in your area, then sends a text the moment it's go-time.
Soil temperature drives everything in lawn care. Apply too early, it's wasted. Too late, the window closes. We track the numbers so you don't have to.
Stop crabgrass before it starts. The window is short.
Crabgrass germinates when soil hits 55°F for 3+ consecutive days. Pre-emergent creates a barrier before seeds sprout.
Light rain Tuesday activates the pre-emergent, working it into the soil. No need to water it in yourself.
In the Chicago suburbs, the pre-emergent window is typically late March to mid-April. Miss it and you're fighting crabgrass all summer.
One bag of Scotts Halts covers 5,000 sqft. You'll have leftover for a second application in 6–8 weeks.
Protect your roots before grubs destroy them underground.
Adult beetles emerge in late June and lay eggs in turf. Grub preventers work best when applied before eggs hatch in mid-July.
GrubEx needs to be watered into the soil to reach the root zone where grubs feed. A good soaking or rain does the trick.
By the time you see brown patches, the damage is already done. Preventive grub control applied in June/July stops the problem before it starts.
Skunks and raccoons tear up lawns hunting for grubs. No grubs, no midnight lawn demolition.
The #1 thing you can do for a Midwest lawn. Don't skip this.
Cool-season grass seed germinates best when soil temps are between 50–65°F. Early fall gives seedlings 6+ weeks to establish before winter.
Most summer weeds are dying off. New grass seedlings don't have to fight for space, light, or nutrients.
September in the Midwest offers ideal 50–70°F temperature swings. Grass loves these conditions for root development.
Fall overseeding fills in thin spots and thickens turf. One weekend of work pays off all year. This is what separates good lawns from great ones.
One last feed before the freeze. Your spring lawn depends on it.
Winterizer should go down while grass is still slightly green and roots are still active. Once the ground freezes solid, the window closes.
Grass stores carbohydrates in its roots over winter. A high-potassium winterizer fuels this process, leading to stronger spring green-up.
Winterized lawns green up 2–3 weeks earlier in spring. Neighbors will ask what your secret is.
