What happens after you type your address, in the order it happens.
Type your address. We read your soil from the USDA survey and show you what to fix first.
Every line is marked measured, estimated or unavailable. When a source has nothing for your address, the line says so. We never fill the gap with a guess.

The paid plan runs your season.
Every job timed to your address, and held when the soil or the heat at your address says wait.
Most crabgrass preventers also stop grass seed from sprouting. Some block new seed for about four months. That's why order matters.New York closes lawn fertilizer season December 1 to April 1. Suffolk closes it November 1, Nassau November 15. Your plan shows you all three dates.Crabgrass begins to sprout when the upper inch of soil holds 55 to 58°F for four or five mornings (Penn State Extension). Your plan watches soil temperature at your address, so the preventer goes down first. Arrives spring 2027
A calendar can't tell you to wait when your soil is still cold. This does, for each part of your yard, with your spreader's setting from the bag's label. Arrives spring 2027
Chris's own season, job by job.Why each job lands when it does.
Five jobs from Chris's own season. Each one shows a different thing the plan does: wait for the soil, count the growing degree days at your address, turn a lab test into pounds, react to what you logged, and keep you inside the law.
Watch one real season play out: what the plan told Chris to do, and why each job waited for its moment.
