It's not too late to add edible plants to your garden. In coldest areas of the Midwest, you can still plant seeds of cool-season crops, like radishes, lettuces, and other greens. You can also add seedlings of broccoli, cauliflower, and cabbages to the garden. In the southernmost parts of the Midwest, this month witnesses the last average frost date. When all danger of frost has passed, plant seedlings of tomatoes, peppers, basil, and eggplants. Annual vegetables: Get potatoes in the ground as soon as possible. Don't plant sweet potatoes until closer to Memorial Day. For more information ">http://www.bhg.com/gardening/gardening-by-region/midwest/april-tips-the-midwest/
