Part XV

Seed starting

Give a last frost date and a USDA zone. The folio returns when to start indoors, transplant, or sow outdoors — vegetables, herbs, flowers, and fruit.

Typical last frost for 6b is the date we filled in. A ridge runs colder than a hollow — treat the week as a window, not a promise. Soil temperature still rules a bean.
