In mid-April I'm going to be moving into a flat in Madison, Wisconsin
that has several raised veggie gardens in the back yard, as well as
blackberry bushes, pear trees, an apple tree, and grape vines. I'd
like to keep this up while I'm living there, but know nothing about
gardening. Are there veggies that come back every year or do I have
to start from scratch? When do I plant different vegetables (zuchini,
lettuce, tomatoes, carrots, onions) and should I use seeds or what?
Do I have to do anything to the fruit besides pick it?

I'd recommend a really excellent book with a highly unfortunate title:
"Gardening For Dummies." I am not flaming you nor is this
intended to offend. This particular book has the basics of
everything you'll need. It has been very valuable to me, & I've
gardened for many years.

When you plant veggies depend on what zone you're in.
Look it up on the net; search for last frost date for your city/town.
I'm right on the line between Zone 6/7 myself, my last frost date this
year is between April 20-30.

For the rest of your questions, search & study. Good luck,
gardening is fun. It's a thrill to see things grow & produce food
& beautiful flowers.
