The composite season in Columbia opens around March and closes after October: coatings wait on warm nights, concrete on freeze-free 48-hour stretches, seeding on the 55–80°F germination band. Between those bookends, the right question is which task fits this week — which is what the verdicts above answer.

Deepest calendar first: start with lawn seeding in Columbia (176 workable days a year), then work down the matrix.
