BASIC ONION GROWING INFO

  • Sun Requirement: Onions require full sun – the more the better! Therefore, avoid planting next to crops that might shade your onions.
  • Soil Fertility: Adding compost or a balanced organic fertilizer is essential for growing healthy onions, especially if soil fertility is low. For the best growth and yield, onions need fertilizer at planting time and additional side dressing throughout the growing season.
  • Planting: Onions grow best on raised beds or raised rows at least 4″ high. Typically, you can plant onions as early as 4 to 6 weeks before the last estimated spring frost.
  • Special Care Onion Plants: These are a favorite among gardeners and farmers for their abundant, high-quality harvests. They’re more delicate than sets and perform better than transplants but need a little extra attention when they first arrive. Because shipping can be stressful, monitor tracking, unpack immediately, give a light watering, and begin re-hardening them off slowly for the best planting success. Although they arrive pre-hardened, easing them back into outdoor conditions with a gentle, gradual re-hardening process ensures strong, healthy growth. If you have any issues, contact us right away—we’re here to help. Give your onions proper early care, and they’ll reward you with exceptional results.
