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?
- 12 inches in-row spacing, 18 inches between rows, and 0.125 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?
- Cut before plants become overly tall if harvesting tender greens. Moderate water for tender leaves; drought increases toughness. Average to fertile, well-drained soil.
