Action plan
- Can I plant this now?
- Use your local last-frost, first-frost, and soil-temperature checks before treating this crop as plantable today.
- Start indoors or direct sow?
- Direct sow or transplant depending on your soil warmth, bed readiness, and frost-risk plan.
- How much space?
- 10 inches in-row spacing, 18 inches between rows, and 0.25 inch seed depth.
- Best companions?
- Use crop-family rotation first, then pair with compatible timing, spacing, and canopy size rather than relying on a simple companion chart.
- Common failure modes?
- Heat and drought make leaves harsh and accelerate bolting. Steady moisture keeps leaves tender and less bitter. Fertile, well-drained soil with moderate nitrogen.
