- Description
-
Shallots are members of the onion family native to Asia. They have a flavor described as somewhere between onion and garlic. It is resistant to damage by deer and rabbits and can be planted near black walnut trees. The bulb will make several offsets during the growing season. The tops can also be used like chives but harvesting these will delay the bulb formation. The creamy bulbs are 2-3 inches long by 3-4 inches wide and depressed oval in shape. The outer covering is tinged with red, purple or brown.
Plant bulbs in moist but well-drained fertile loose soils in full sun as soon as the ground can be worked in spring about 1/2 to 1 inch deep and 6 inches apart. The bulbs are ready to harvest when at least 2/3 of the tops have died down. Dig shallots with a garden fork to prevent damage and allow to dry or "cure" for 2-3 weeks before using. Store in mesh bags or crates for good air circulation.
Insects, Diseases, and Other Plant Problems: Bulb mites can occur. Bulb rot in too-wet soils can occur.
