Lettuce in Zone 4a
Lactuca sativa
Method: Either — Start indoors for an earlier harvest, or direct-sow outside for less fuss — Lettuce tolerates either.
| Start indoors | Apr 17–Apr 24 |
|---|---|
| Direct sow / transplant outside | May 1–May 8 |
| Estimated harvest | ~45 days after planting |
Spacing: 4 per square foot (square-foot-gardening spacing).
Good companions
- Carrot — Shallow lettuce roots don't compete with deep carrot roots.
- Radish — Radish matures fast and breaks up soil for lettuce.
