Compact, Efficient, Veggie Garden Machine
Here, in upstate NY where I live, the soil is hard clay and rocky. Over 20 years I have always planted a veg garden, if only to grow tomato plants, and sometimes chard, acorn squash, wax beans- all pretty expensive in the supermarket.
Each time I would manually re-dig the garden, experimenting with raised gardens, soil enhancement and the like. It's getting old now and I rethought the whole process to come up with the "Veggy Garden Machine", which has turned out to be a success with lots less labor (except at first). In succeeding planting seasons, I remove the old plants, add some fertilizer and topsoil, and replant with very little hard digging. Alter this scheme as you wish; it'll be more fun.
If you have similar intractable clay soil, or wish to add some of the garden refinements to your existing garden, read the PDF instructions. You will be able to establish raised, well drained, garden beds that you can easily reuse every year, that contain strategically enhanced soil, that almost waters itself, and that supports your tomato plants well (mine grew to 5 feet and more). My pictures should give you a good idea of what it's like, and my instructions following are exhaustive. The total garden size is 12-14 feet square or in diameter.
