Growing Info

Harvesting: When onion tops have fallen over and turned yellow or brown, they are ready for harvest. Harvest in the morning, lifting onions with a garden fork. Dry them in the garden in the sun for 2 to 3 days, lightly covering the bulbs with straw, or the tops of other onions to prevent sunscald. Cure onions for 3 to 7 days in a dry area with good air circulation. Once dry, cut the roots to 1/4", and the greens to 1" to create a seal, preventing decay.

Special Care: Keep growing area weed-free. Onion size can decrease 4% per day if competing with weeds‒that’s 50% in 2 weeks. If bulb pushes itself out of the ground, you may cover it lightly with straw, but not soil, as soil will prevent the onion bulb from forming properly.
