Early crop in Zone 4. How to Plant Onion Plants -
These need to be planted about 1 ½ to 2 inches deep and about 3 inches apart.
After Planting Onion Plants - I do not pull these for green onions as I want them to grow bigger for summer eating in salads,
salsas, on burgers, etc. Their shoulders come out of the ground, that's okay, that's how an onion grows! Be careful if hoeing, so as not to nick the bulbs. This can cause a rotten spot.
Harvesting Onion Plants - These tops need to dry down also. Harvest about August 18-25. Dry in your garage and then store in paper bags. These do not store very long, about to Christmas.
