Summer time is fun for gardeners. Above you see chives (wonderful for garnishing soups and of course they are great with baked potatoes) and sweet basil (I'm a big pesto fan). Here in Southern California we can grow vegetables and herbs year-round, but summer is when we grow the good stuff: tomatoes, basil, beans, peas, zucchini, and cucumber. I use the Square-Foot Gardening technique by Mel Bartholomew (or the updated one is here). There are differences in the books; some reviewers recommend them both for the most complete reference.
Here's the big picture: you build raised garden boxes (I made mine four feet by six feet out of two-by-twelve redwood boards and lined on the bottom with chicken wire to keep out root-loving gophers). You import nutrient-rich soil and divide the boxes into one-foot squares. How many plants per square depends on the vegetable. Lettuce, basil, chives all are four plants per square. Tomato is one per square. Zucchini requires nine squares (a three-by-three portion of your garden box, as shown above).
Chives have beautiful flowers and buds that give your garden a bit of color.
These tomatoes are getting there. And, here are my pole beans, just beginning their climb to the sky.
