Evergreen Bunching - Onion Seeds

Start seed indoors 6–8 weeks before transplanting into the garden. Optimum soil temperature for seed germination is 65–70°F. Transplant to the garden about 2–4 weeks before your average last frost. If seedlings begin to tip over, trim tops to about 3”. Bunching onions can also be direct sown from early spring into midsummer. Plant in full sun and fertile, well-drained soil, and keep evenly watered and weed free for best growth. Established clumps may be divided to produce additional plants. Harvest young or at full size as needed.
