I run a garden center down here in St. Peter and the best advice I always give new vegetable gardners is: Don't be afraid to wait. As in waiting until the ground warms up. Tomatoes and peppers will sit dormant in the soil until it warms. Don't be afraid to wait until Memorial Day to plant, in some years I haven't gotten my garden in until the 4th of July and still had plenty of harvest. While there are cool season vegetables such as leafy lettuces, many of our favorites such as tomatoes, peppers, and cucumbers don't do well until the soil has warmed in the spring. You'll always want to see what the tag or seed packet says in regard to maturity to make sure you have enough growing season. It is safe to say that our growing season runs conservatively from May 20 to Sept 15. That is give or take about 125 days. It sounds as if you are interested in doing a "salsa garden". This is great way to start. All you need is a few tomato plants, some peppers, and it sounds like you would be interested in onions as well. For tomato's as you gain experience it is fun to try different heirloom varities, exotic looking strains, and whatnot, but they can be somewhat susceptible to blights and other diseases. For the beginner gardener it can sometimes be easier to use the tried and true varieties, you can't go wrong with Roma's, Big Beef's, and Brandywine's, they are just a few of the varieties that do well in our climate and make a good salsa. As for peppers, Jalapeno's, Cayenne's, and Chile's all are easy to grow. As for onions I agree with Eurolarva, onion sets are easy and cheap, they like a soil that is free of large clumps. Just a few tips on making the garden area useable again, I do this quite often and is IMO the most efficient way to get rid of the weeds, is to rent a manual sod cutter from your local rental store (usually about $15), you use the force of your foot to shave of two or three inches of soil from your area. Then bring in enough topsoil or compost and till that into the ground. There will be some roots from the quack and regular grass left, but nothing that can't be handled from weeding. It is always a good idea to put mulch on top to limit weeding later in the year. Just don't put the mulch down too early as you want that dark ground to absorb solar energy and warm up. I could get into constructing a raised bed with a couple of 2 by 6's, that might be the most surefire way to eliminate the weeds right away, but I can expound on that at a later time. One last point I'll make, and some seasoned gardeners might not agree, but the easiest way to start a garden is to get the plants already started. There is something to be said about personally raising a plant from seed till harvest, but much hassle is saved, especially with a smaller garden by just buying the plants already started in a 4- or 6-pack. The most important part is to have fun!
