For cherry tomatoes, a cage is recommended and generally 1-2 plants will produce plenty for the family. Tomatoes will need to be picked every other day or so.
Peppers--Plant each 2ft apart and use a smaller tomato cage to keep fruit off the ground and to reduce summer wind damage.
Broccoli, Cauliflower, Cabbage & Collards--Plant each 2ft apart and allow 4ft2 per plant
Potatoes--Potatoes should be planted in mid to late March. Space 5 potato plants in a 16ft2 area. Potatoes need to be “hilled” throughout the growing season, so additional compost or soil will be needed.
Cucumbers—Plant 2ft apart and allow 4ft2 for each plant. Suggest getting dwarf types so vines don’t take over other things. Vines can be trellised, but will need some training.

Instead of planting in rows, plant following spacing between seeds listed on seed packet in a checkerboard pattern to maximize space.
