Starting Vintage Tomato Seeds Indoors in Michigan

Vintage tomato seeds deserve a strong start. In lower Michigan (last frost ~Memorial Day), wait until early April to sow—starting too early leads to leggy, root-bound plants.

Essentials for Success

Light: 14+ hours daily from fluorescent lights (cool + warm bulbs) 2–3 inches above seedlings.
Soil: Sterile soilless mix only—no garden soil or compost.
Moisture: Cover with dome until germination, then remove to prevent damping-off.
Feeding: After second true leaves, use diluted fish/seaweed emulsion weekly.

A west-facing windowsill won't provide enough light. Invest in a simple shop-light setup. Transplant into larger pots twice before hardening off. Your patience will pay off with sturdy, productive plants.
