Bed Preparation
Soil should be slightly moist and well drained. Full sun is best for growth but partial shade can also work. Plant onions in a location that allows them room to roam.
Planting
Plant in spring or in fall. Plant each top set 2" deep, with 6"-10" between plants and 1' between rows. They may also be planted close together in clusters for an ornamental addition to any garden.
Cultivation
Cultivate as you would regular garden onions, keep weeds to a minimum and lightly mulch and fertilize when needed.
Harvest
Harvest top sets in late summer and fall when the leafstalk has turned brown and begun to dry. Harvest the long green leaves of the onions (the ones without the top sets) year round. Harvest underground onions in late summer and fall – remembering that when removed this onion plant will no longer grow the following year.
Curing and Storage
Onions can be cured by being placed in a warm area with good ventilation. Allow them to remain until they are cured and the necks are fully dry (about two weeks). This will allow them to store longer in a dry area with low humidity and well ventilated containers.
