If you are thinking of bringing some kids along to the garden, here a couple of websites that might be useful:
Got Dirt? (UW Extension, Brown County)
National Junior Horticultural Association
U of Illinois Extension - My First Garden
Gardening with Kids
another Gardening with Kids
Kids Gardening
Wisconsin Master Gardener program works with youth
And don't forget the importance of being kind to the earth and integrating green gardening techniques. This recommended reading list has lots of suggestions to get you started. The library just ordered a few "gardening with children" books that we'll add to the list.
Happy digging!
