Sun: Plant in full sun (6 to 8 hours). Space 12 to 18 inches apart within rows. Plant in February and October.
Soil: Amend with organic matter to create a well-drained soil. Avoid planting in unamended sandy or heavy clay soils. If the soil test shows the pH is below 6.2, apply lime as recommended.
For proper drainage in a container garden, use potting mix and ensure containers have drainage holes. Alternatively, consider using self-watering containers.
Water: Keep soil consistently moist but not saturated. Apply 1 to 2 inches of water each week and more during hot summer days. Keep leaves dry to avoid fungal diseases. Mulch helps retain moisture.
Plant: Direct sow seeds about 1⁄2 inch deep. If buying transplants, choose those with healthy color and a stocky appearance. Avoid plants with flowers. Dig the planting hole as deep as the root ball. Firmly pat down the soil and water deeply.
Fertilize: In the absence of a soil test, apply an all-purpose fertilizer (8-8-8 or 10-10-10) at planting, according to label directions. Apply nitrogen 4 to 6 inches from the stem (side-dress), 4 to 6 weeks after planting.
Insects/Diseases/Weeds: Scout plants frequently for insect and disease damage. Use insecticidal soap (for soft-bodied insects) or Bt dust or spray (for caterpillars, or worms). Spray fungicides regularly to suppress common fungal diseases. Always follow label instructions. Mulch inhibits weeds and diseases.
Harvest: Harvest at 50 to 70 days. Harvest time varies depending on the variety.
