Spring Entry
March – May
What's Happening Underground
The lawn wakes up. Soil temperatures climb, cool-season grass breaks dormancy, and the first flush of growth begins. But so do crabgrass seeds — they germinate the moment soil hits roughly 55°F for several days. Spring House's larger, shaded lots warm slower, so the pre-emergent window here can lag a week or two behind the open, full-sun boroughs.
What Most Homeowners Miss
Most homeowners see green grass and assume everything's fine — then miss the crabgrass window entirely. Once you see crabgrass plants in May, the pre-emergent is already too late. The other miss: seeding bare spots in spring. In Eastern PA, spring seed fights summer heat and crabgrass pressure before it can root, so it mostly fails.
What Golden Green Does
We time the pre-emergent to soil temperature, not the calendar — critical on Spring House's shaded lots that warm later. We start a measured fertility program that feeds the root system, not just top-growth. And we hold bare-spot seeding for late summer unless the spot is urgent, because spring seeding in Pennsylvania is a bet we usually lose.
What to Expect
Crabgrass stays out of the lawn this season. Color returns evenly. Any bare patches get flagged for the fall entry — not wasted on spring seed that won't survive July.
