Preserving Food Safely - 01600008


Harvest onion family crops when the tops have died or in
the late fall before the ground freezes. Allow the plants
to dry for several weeks before storage. Spread them out on
on an open screen off the ground.

Do not try to store bruised or thick-necked bulbs. Storage
should be in a dry, well-ventilated area with a temperature
near 32 degrees Fahrenheit. Place the bulbs in mesh bags,
fill bags half full, and hang them from overhead hooks in
the storage area or place them in open slatted crates,
half full, and stack crates on cross bars.

Slight freezing will not be harmful if the bulbs are not
handled while they are frozen. When stored properly, the
onion family bulbs should keep through the winter.
