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, 8 inches between rows, and 0.25 inch seed depth.
- Best companions?
- Use this as part of a diverse flowering or herb planting, and treat companion claims as site-specific rather than guaranteed pest control.
- Common failure modes?
- Hot weather makes leaves sharp and triggers flowering. Consistent moisture keeps leaves tender. Loose, fertile soil.
