Plant a trio of corn rows together for the pole beans to climb onto; consider shade cloth if the sun hits the garden hard. Trelis the peas (chicken wire works well) and cucumbers (cut wooden x trelis in half the long way) in an upside down V...in short rows so you can reach under the trelis to pick the produce. My dh got a whole thing of wire used in cement reinforcement (4x4 welded wire) and cut it into pieces so it would make a cirlce about 30 to 36 inches for tomato support. Works well and can be reused every year. He threads a steel post through one side and drives it into the ground so high winds do not destroy the plants.
We use old semi or tractor tires, mix our own soil like greenhouses do that holds mositure for the roots of the plants. Easier to weed, easier to pick, and really produces the lovely produce. Sand is needed for any beet or carrot seeds. Try some Heritage seeds...and some resistant to disease. Have fun!!
