Tomatoes, muskmelon, cucumbers, green beans, watermelon, onions, carrots, corn, basil, peppers, lettuce, broccoli, peas, parsley, oregano, lavender, and mint. ’
I used 2×6’s for the 2×2’s, with a 3/8’’ piece of plywood on the bottom, plus handles to move around. The 3×3 is made with 2×8’s with newspaper on the bottom to stop weeds and grass. The 3×3 remains stationary. I used 1/2’’ EMT electrical conduit and pulling L’s to create a trellis, about 6’ high, on 2 sides for tomatoes, cucumber, green beans, and muskmelon.
Since the muskmelon(canteloupe) needs 2 square foot for one plant, I put in the corner of the trellis, so it had 2 feet of trellis to grow up, not one.
This year, I will be planting all of the same, with the addition of zucchini and eggplant. I also bought a blueberry bush, and will be building a 2×2 box, with handles, for that.
The blueberry bush, needs acidic soil, so should not be planted with the veggies I mentioned above.
The book I got on SFG was written by Mel Bartholomew. He explains everything in laymans terms, and even shows you the exact mixture of soils, which in my opinion, worked out great. He also explains how to compost, which is very important in creating healthy, rich soil.
Good luck and happy planting.
