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?
- Start indoors, harden off, then transplant into the final bed when local timing is safe.
- How much space?
- 18 inches in-row spacing, 30 inches between rows, and 0.5 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, drought, or uneven growth can reduce head quality. Keep soil evenly moist; stress interrupts curd formation. Fertile, well-drained soil with consistent nitrogen.
