for best yields?
Best time to plant onions is when soil temperature reaches 65 degrees F. Plant seeds 6 inches apart in rows 12-18 inches apart. Up to 50% of the seedlings may fail during transplanting, so multiple transplants are recommended for highest yield potential. To help strengthen the plants, apply a starter fertilizer at planting and again three weeks after transplanting. Upon harvest, allow onion tops to dry well on stalk before stripping tops from bulbils/scapes which will keep bulbs strong down through next season’s growth cycle.
