Plant & Growing Tips

Sweet Potatoes

  • Plant slips in full sun after the last frost, in well-drained, sandy soil.
  • Ensure consistent moisture, especially during tuber formation, and mound soil around the base to encourage more growth.

Red Cabbage

  • Sow seeds indoors 4-6 weeks before the last frost or direct sow in cool weather, providing full sun and rich, moist soil.
  • Space plants 18-24 inches apart to allow for proper head development.

Lime

  • Grow lime trees in large containers in full sun, bringing them indoors when temperatures drop below freezing.
  • Provide consistent watering and well-draining soil, fertilizing regularly during the growing season.

Coriander

  • Sow seeds directly in cool weather, as coriander bolts quickly in heat; choose a spot with partial shade in warmer climates.
  • Keep the soil consistently moist to encourage lush leaf growth.

Natural Pest Control

  • Protect young cabbage plants from cabbage worms by covering them with fine mesh row covers.
  • Hand-pick sweet potato weevils and practice crop rotation to prevent their buildup.
  • Spray aphids on coriander and other plants with a strong stream of water or a mild insecticidal soap.

Harvest

Sweet Potatoes

  • Harvest when leaves start to yellow and die back, typically 90-120 days after planting slips.
  • Carefully dig up tubers with a fork to avoid damage, then cure them in a warm, humid place for 1-2 weeks before storing.

Red Cabbage

  • Harvest when the head is firm and dense, before it splits, by cutting the stem at soil level.
  • Leaving a few outer leaves can sometimes encourage smaller secondary heads to form.

Lime

  • Pick limes when they are fully green, firm, and heavy for their size, as they do not sweeten further once picked.
  • They can be stored at room temperature for a week or in the refrigerator for several weeks.

Coriander

  • Snip outer leaves as needed once plants are 4-6 inches tall, using the cut-and-come-again method.
  • Harvest entire plants for a larger yield before they flower, as flowering reduces leaf flavor.

Storing & Freezing

Components keep 3 days; assemble fresh.
