Be sure the soil can be amended to drain well, or plan to build a raised bed. Measure the space available and draw it on graph paper. Design for just one favorite or make your own combinations. Estimate the number of plants you can fit in based on their mature size. Then design for the longest harvest possible - draw in early varieties interplanted with later ones.
Design trellises into the garden to maximize space for snow peas.
Add permanent hoops to support floating row covers, shade cloth or plastic-film season extenders. Chinese specialty vegetables plus perennial favorites horseradish and asparagus. Double dig the northeast corner of the garden for the longer-lived perennials. Cultivate delicate local favorites that are grown for unparalleled flavor but are impossible to ship. Design a space in your garden to leave room for the unexpected package of pass-along peas.
