How to Read This Calendar

1

Start indoors

Sow in trays under strong light. The window is timed so seedlings reach transplant size without becoming root-bound.

2

Transplant or plant

Harden seedlings off for about a week. Perennial crowns, sets and seed potatoes are included in this column.

3

Direct sow

Plant seed directly into prepared soil. Cool-season crops can begin before frost; heat-loving crops need warm soil.

4

Last planting

This is the practical end of the selected window—not a guarantee. Variety maturity and unusual weather can move it.
