Garden Planning: Crop rotation is the practice of moving crops around yearly or seasonally, rather than planting the same thing in the same place year in and year out. Rotating crops gives the soil a chance to cycle nutrients and minimizes build of of the pathogens to a particular plant in that area. For example, if you always plant tomatoes in the same spot, even with added compost, the tomatoes will tend to tap out the particular nutrients that tomatoes like. At the same time particular tomato pests and diseases will tend to gather in that spot The combination of diminishing nutrient and increasing potential for attack is a recipe for crop failure. Smart crop rotation alternates plants that build soil nutrients with those that are heavy feeders. A typical rotation would be to plant a soil builder every third rotation, with a heavy feeder and a light feeder in between. Soil building plants are all in the legume family, as they “fix nitrogen” from the air with the help of bacteria. Examples are fava beans, soy beans, pole beans and peas. A heavy feeder need extra nitrogen to perform. Examples of heavy feeders are basil, beets, corn, lettuce, squash and tomato. Examples of light feeders are carrots, leeks, onions, peppers and potatoes.
In a small garden it may not be possible to rotate everything in as grand a fashion as on a larger farm with copious sun. Perhaps you have only one sunny bed that tomatoes will work in for example. Still you can rotate your tomato planting with a winter crop of fava beans or other legume. To keep track of your rotations, create a small drawing of your garden each year and notate what went where.
Book Review The Vegetable Gardeners Guide to Permaculture by Christopher Shein with Julie Thompsen. The much anticipated new book by local permaculture hero Christopher Shein has hit the shelves. This is a gorgeous book filled with large full color pictures, diagrams and maps. The book is comprehensive, yet also spacious and easily digested. After a clear and simple introduction to the ethics and principles of permaculture, the book dives into how to design your garden using design elements from the permaculture vocabulary. Food forests, fruit tree guilds, zones, sectors, inputs and outputs are elegantly described along with easily understood diagrams and sample designs to put them into action–from a balcony garden to a large urban lot. The book goes on to offer techniques for soil building, a plant-by-plant compendium of perennial edibles, annual vegetables, edible flowers, herbs, seed starting and seed saving. The sections on animals for your backyard systems are slim and not well developed. But overall this is a lovely addition to your gardening library.
