Most produce suitable for storage needs a high-humidity environment. Produce that keeps best in a moist environment includes root vegetables, cabbages, kohlrabi and some varieties of fruit. See chart below.
Apples & Pears: when harvesting fruits of the Rosaceae family, be certain to leave stem attached and don’t wash before placing in storage. Thoroughly inspect for worm holes and bruises.
Grapes: harvest grapes with main stem intact. Snap where the grape cluster’s stem joins the vine. Don’t wash before placing in storage.
Citrus: harvest fruits with stem. Don’t wash.
Root vegetables: pull and trim the greens to 1/2 inch above vegetable. Do not trim any roots.
Cabbage: pull cabbage up by roots and leave everything intact. To lengthen shelf life, open leaflets may be gently tied down to preserve the insides.
Kohlrabi: cut ball from roots. Trim leaves close to ball. No other action necessary
Potatoes: dig in last 2 weeks of warm weather. Spread to “heal” in a warm place (60F-80F or 15C-26F, out of direct sunlight. Never cure potatoes in direct light. Let ’em rest 2 weeks to heal nicks or removed peel. No other action needed.
