Shallot Growing Information Allium cepa var. Aggregatum Direct Seed: In regions with long, warm growing season, seed as soon as ground can be worked. Soil temperature for germination is 50-80° F. Transplant: Can sow multiple seeds per cell or pot. Separate seedlings when transplanting. Bury plants as you do onions, up to 1st leaf joint. Spacing: For direct seeded crop, seed 1” apart at ¼" depth. Thin or set transplants at 3-4" apart in rows that are 18-30" apart. Growth needs: Grows best in well-drained soil with high organic matter, in full sun. Make sure to keep planting well weeded with good air circulation. Shallots are day-length sensitive and should be planted like long day onions. Harvest: Ready when tops fall down and necks are soft. Pull out of soil and cure in the sun for up to 1 week. Finish drying in a well-ventilated barn or covered space. Storage: Clip tops once dried and store in mesh bags at 34° F with 60-70% relative humidity.
