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 into the final bed when the soil temperature, seed depth, and moisture are ready.
- How much space?
- 4 inches in-row spacing, 12 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 and crowding make roots sharp and pithy. Even water keeps roots from becoming woody. Loose soil with steady fertility.
