Re: If you only had a 10' x 10' garden, what would you grow?
First plan what you want to eat. Corn on the cob, Tomato Soup, Stewed Tomatoes (peppers & onions, Spices), Pizza, Sun Dried Tomatoes, Basil, Squash/Eggplant/Onions, Fried Okra.
Stick with good growing plants for your area, tomatoes, peppers, corn, peas, beans, squash, zucchini, eggplant, okra, onions. Avoid large flowering or space hog plants. lettuce is too tempermental, besides its $1 a head. Cabbage, turnips, greens use too much space for small micro-plot. Kale, Swiss chard, Korabi hyped by Mother Earth News, check their small garden recommendations.
From Garden Show, either, free standing (2 outside walls) corner trellis, or 4-sided (Reach into center) mini plot in middle of yard. Good for climbing or staked plants, beans, tomatoes etc.
use 2x2 sharpened point into ground .. plastic coated welded wire fencing inserted into drilled holes .. use top and bottom separator 2x2 to make rigid frame. Offset adjacent panel holes by 2 inches. (On corner unit use brace bar at top, mid, and lower area -- can be used for hanging planters.) push at least 1 foot into ground for stability.
Martha Stuart Special I think, Plant Pizza Garden - Herbs/Spices, Peppers, Onions, Tomatoes, to make pizza cheaper at home. Spices do ok in multiple, growing boxes on a wall in sunny area. Sick a couple flower plants at ends and looks better.
Try old Indian garden method, corn for support, climbing beans, and squash plant at base.
Dig along fence line and plant Fig Bushes and Fruit trees (peach, plum, pear, whatever grows good, avoid apple), Pecan, Hickory nuts take 5 years minimum. Strawberries, blueberries in-between.
