how long for onions to transplant
Start onion seed about 8 - 12 weeks before your transplant date. Plant onion seed about 1/4 - Â½ deep. You can plant thickly and thin at transplant time. Keep the soil moist. As the tops grow, keep them trimmed to about 4. Transplants or onion seedlings will need to be hardened off before planting outdoors.
