In Littleton, we planted Early Flat Dutch and Copenhagen Market cabbage, Waltham 29 broccoli, and a beet mix in flats in the greenhouse, under row cover. We used our standard potting mix, a blend of peat, compost, and perlite amended with lime, bone meal, azomite, and organic fertilizer.
A farmer kindly brought his tractor and chisel plow in to break up the vegetable garden area. So we now have 10,000 square feet of broken ground. (About a quarter of the whole field.) Since the weather is dry and hot, all the grass should be dead in a day or so. We will have to get to work quickly to take advantage of the open ground before weeds do. Part of the garden will probably be mulched in preparation for planting, part will be sown with a cover crop before tomatoes and squash are planted at the end of May, and some beds will be worked into a fine seedbed without mulch for planting cool weather, small seeded crops like lettuce.
