Growing tips
- Spacing: 12 inches between plants keeps air flowing and limits disease.
- Depth: sow seeds about 4″ deep (or set transplants at the same soil line).
- Sun: Full sun (6+ hours).
- Season: Tolerates light frost; best in cool weather, sow in spring and again in fall.

Spacing, depth, and days-to-harvest are typical values from university extension guides. Planting dates are computed from typical USDA/extension freeze dates (USDA Plant Hardiness Zone Map (2023) + state cooperative extension typical freeze dates); confirm locally before acting.
