Can anyone tell me how to grow large onions to keep over the winter?also someone told me that if you plant the green tops of an onion it will make bigger heads on them .Has anyone done this before?
There are 2 basic ways to grown onions. Either by seed or by sets(baby onions) I personally always grow sets. In fact I normally grow shallots, same as any onion but you get more for your money as the bulb splits, and they are milder. Either way you first get your ground to a fine tilth, mark your rows out and plant. If it be sets you be planting then push them into the soil till just the tops are visible else birds pull them out. Don't let them dry out and watch them grow. When they be big enough knock the growing stalks flat, gently pull from soil so's the roots are still in the ground and let them dry. Then lift and dry in a light airy place out of the rain till they be dry, then to store just put them in the legs of old tights or stockings, knot at each onion and hang in a cool dry place garage or shed. When you want an onion just cut one off. A lot easier than trying to plait the onion helms in a string I can tell you.Your supplier will tell you what size onions you can expect. I never had much success with seed as I kept pulling them out thinking they were grass. Good luck, I usual plant early march, I live in Sussex so's you may have to adjust for your time zone.
