Carrots, like dill and parsley, are in the Umbel family.

Rotating Vegetables by Family

Rotating vegetables is always recommended, but to do it properly, one needs to know which vegetables are in the same family.  Related vegetables share disease problems, so a true rotation needs to be between vegetable families.  Usually a 3-year rotation is advised, meaning that there will be 2 years of unrelated vegetables in the middle, between related vegetables.

Here are the most common vegetable, herb, and cover crop families:

 FAMILY MEMBER PLANTS
 Allium chive, garlic, garlic chive, leek, onion, perennial onion, shallot
 Amaranth amaranth
 Brassica bok choi, broccoli, Brussels sprouts, cabbage, cauliflower, Chinese cabbage, collard, horseradish, kale, kohlrabi, mustard, rutabaga, radish, turnip
 Composite artichoke, chicory, endive, Jerusalem artichoke, lettuce, sunflower
 Curcurbit cucumber, gourd, melon, pumpkin, squash (winter & summer), watermelon, zucchini
 Goosefoot beet, chard, quinoa, spinach
 Grain barley, corn, oats, rice, rye, wheat
 Legume bean, clover, pea, vetch
 Lily asparagus
 Mallow okra
 Mint basil, mint, oregano, sage

2012 USDA Hardiness Zone Map

The 2012 USDA Plant Hardiness Zone Map helps gardeners and growers determine which plants are most likely to thrive at a location. For the first time, the map is available as an interactive GIS-based map, for which a broadband Internet connection is recommended. Users may also simply type in a ZIP Code and find the hardiness zone for that area.
