Remember also that frequent opening of the refrigerator door raises the temperature inside. Basements are also possible storage places. Separate sections can be partitioned to vary the temperature and humidity. You can use outdoor air, dirt floors or wetted sacks to vary the temperature and humidity needs. Unheated basements, if well ventilated, can provide good storage conditions for some vegetables.
Different vegetables require different temperature and humidity levels for proper storage.
Begin harvest when beet is 1 inch in diameter or smaller for baby beets. Main harvest is when beets are 2 to 3 inches. Tender tops make excellent greens regardless of the size of the root ball. Harvest fall beets before the first moderate freeze. Storage life is 2 to 4 months.
