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.

Vegetable · Tuber

Potato

Solanum tuberosum

Plant tubers
Mar 18 – Apr 8

Seed potatoes, not grocery sprouts. When the redbud thinks about it, not in a February bog.

Plant tubers 1–4 weeks before last frost. Soil about 50°F before anything goes in the ground.

Sweet potato

Ipomoea batatas

Start indoors
Feb 18 – Mar 4
Transplant outdoors
Apr 29 – May 13

Slips from a jar of water, then warm soil. A cold May week stalls them.

Start indoors 6–8 weeks before last frost. Transplant 2–4 weeks after last frost.
