Springtime, for many, means vegetable gardening and the first hint of warmer weather can make us eager to start. Starting too early, however, leads to poor results. I try to stick to the dates below (my rough calculations based on the book Square Foot Gardening)
Kalamazoo Earliest Planting Dates
April 10: Peas, spinach (from seed)
April 20: Broccoli, parsley (from transplant)
May 1: Carrots, lettuce, onions (from seed)
May 15: Potatoes
May 31: Tomatoes (transplant), summer squash (transplant or seed), beans (seed)
June 15 Peppers (transplant)
