Advanced crop rotation: Plant families

Advanced crop rotation: Plant families
Photo by Tim Parkinson, shared via Flickr.
In my post last week about crop rotation, I covered the very basics: moving plants from year to year helps preserve soil fertility and prevent pest problems. But as you might know, some plants are closely related to each other, and that complicates matters a little bit.

To help illustrate the related plants, I've adapted this list below from a great list at a University of Illinois Extension website:

Nightshade family: tomato, pepper, eggplant, potato, tomatillo
Onion family: onions, garlic, leek, shallot, chives
Squash family: cucumbers, muskmelon, watermelon, squash, pumpkin, gourd
Mustard family: cabbage, broccoli, cauliflower, Brussels sprouts, kohlrabi, turnip, radish, Chinese cabbage, kale, collards, mustard greens, rutabaga
Legume family: garden pea, snow peas, snap peas, sweet peas, snap beans, lima beans, soybean
Grass family: sweet corn, popcorn, ornamental corn
Carrot family: carrots, parsnip, parsley, celery, dill
Goosefoot family: beet, Swiss chard, spinach
Sunflower family: lettuce, Jerusalem artichoke, endive, salsify, sunflowers
Mint family: mint, basil, lemon balm, catnip

Now, how do you use this information? Well, the plants that are in the same family should be treated like a single type, in the sake of rotation. For instance, you might have this row order;

Year 1
Potato (Nightshade)
Cucumber (Squash)
Pumpkin (Squash)
Carrots (Carrot)
String beans (Legume)

For year two, instead of moving all the plants one row down, you'd want to take into account your two squashes - so move everyone two rows instead.

Year 2
Carrots (Carrot)
String beans (Legume)
Potato (Nightshade)
Cucumber (Squash)
Pumpkin (Squash)

Many gardeners don't plant in rows, but instead in blocks or even just zones. That's fine, too. In that case, to help you remember where you've placed things in the previous year, a garden journal is helpful. Otherwise, you might be staring into a lovely field of fresh soil in April saying, "Now was it last year that I had zucchini here, or two years ago? Hmm...."

Book review: “Fresh Food from Small Spaces”

Book review: “Fresh Food from Small Spaces”
My book would be called "How To Grow Peppers By Ignoring Them Completely." (Photo taken a month after first frost.)
When my husband first began teaching, he was amazed at the number of textbook offers he got each semester - publishers who wanted him to review and rate existing textbooks. Some even wanted him to suggest ideas for new ones, and they offered to help him submit manuscripts. "This is ridiculous!" he would often say. "Why would I write my own textbook when there are so many others out there?"

After a few years of teaching, however, he began to see why this idea was so appealing. One book might have excellent information in one area, but another area was under-represented or poor; if he was teaching a complex course, he'd have to pool together information from several texts. And some information seemed to have been left out of all the books completely; in those cases, he'd assign reading from periodicals or even (gasp!) websites.

R. J. Ruppenthal began writing Fresh Food From Small Spaces: The Square Inch Gardener's Guide to Year-Round Growing, Fermenting and Sprouting after a similar experience. In the introduction, he writes, "I know firsthand of the need for this book, because I have been searching for it for many years." An staunch urbanite, he wanted to know how he could make the most of the space he had to grow usable, practical foods - enough for his family, and perhaps a little left over to share, barter or sell. (He got points in my book for using "grow" in a more expansive sense: not just fruits and vegetables but also honey, sprouts, eggs and mushrooms.) So he set to work doing research, and he came up with this collection of information.

The problem with the book, then, is exactly what makes it so useful to Ruppenthal: it's very personal. Not personal in the way of gardening memoirs, which use narrative to communicate important information; personal in the way of prioritizing according to fancy. For instance, there's a small section on cold frames (that actually references this book) but the author stops there, casually mentioning that you can buy a kit for around $100 online before moving on. When he comes to self-watering planters, however, he spends several pages detailing exactly how to make your own - and includes several down-and-dirty photos of what looks like a project he completed in his garage. Most of the ideas in this book suffer from similarly thin research; the three "t's" of vertical gardening (terracing, trellising and tumbling) are described in very little detail and without enough information to actually do it yourself, without getting some more books. A section on beekeeping is admittedly drawn from "books and from others who have raised bees and told me about it." The compost section contains both too much detail (charts detailing the N-P-K content of common manures) and too little (an interesting story about a sheet composting that takes a nosedive when the author admits he "cannot yet report on the results because the pile is still decomposing.") It reads very much like a personal journal, which it more useful at some times than others. The presence of many stock photos also erodes some of his credibility; it's as if he cobbled all of this information together to make a presentation, and he waited until the night before to look for visual aids.

The good points: There is a lot of good, solid information about fruit-bearing plants, both where to buy them and what to expect from them. Again, there is a disproportionate amount of information about pollination, but that was obviously a personal interest of his. The section on sprouting is also quite useful, including several recipe ideas to use up your bounty. The chapter about fermented foods (yogurt, kefir, sauerkraut, etc.) is interesting, although I found Nourishing Traditions a far more thorough and well-researched source of information. I also thought the chapter titled "Survival During Resource Shortages" was both wise and timely.

This book falls into the category of books whose first chapter really, really excited me, but it failed to deliver. It could have been much more successful as a compendium of resources and data - where to find out more information about topics that interest you - or as a meandering memoir of a city-dweller with a conscience and a strict budget. I wish I could have read that book. But maybe that means I'll have to write it myself!

Book Review: “Country Wisdom & Know-How”

Book Review: “Country Wisdom & Know-How”
Image by newagecrap, shared via Flickr.
If you're like me, you think of yourself as just a little more self-sufficient than most people. My friends oohed and aahed, for instance, after finding out that I make my own butter from raw cream I buy from an Amish farmer. I shrugged it off; I pick up the food from a drop point about 10 minutes from my house, I told them, and "churning" butter is as easy as shaking a sealed jar for 20 minutes or so while checking my e-mail with the other hand.

But secretly, I enjoyed that praise. I enjoyed thinking of myself as the kind of person who doesn't use paper towels or own a television. I flattered myself that I could "rough it" as well as my great-grandmother, Amish herself. Then my brother dealt me a cruel hand: he embarked on a solo road trip from Baltimore to Montana, where he spent the summer wrangling horses in the wilderness, camping outside and growing his hair into one giant dreadlock. And before he left, he gave me this book.

Don't get me wrong - Country Wisdom & Know-How is about as good a manual for living as you'll find anywhere. It's exhaustive and exhausting all at once. There is almost no domestic or agricultural task that is not represented here; the printing is tiny and the pages are large, no-nonsense newsprint with hundreds of carefully labeled line drawings. But if you thought you were pretty countercultural, it will school you within an inch of your life.

The book is a compilation of information from Storey Publishing's Country Wisdom Bulletins, small booklets which were published in the 1970's during the "back to the land era." They were simply and directly written, with easy-to-follow diagrams, and millions of copies were sold to eager do-it-yourselfers. The Bulletins have been divided into six basic categories, all of which are tied in some way to agriculture and gardening, in keeping with the belief that natural is better.

Animals: Here is where you can easily get lost for hours learning how to identify, attract, feed, bathe, house and care for all kinds of wild birds (including a formula to be fed to abandoned babies, every fifteen minutes for twelve hours a day, until you can get more professional help: dog food, egg yolk and baby cereal!) Or you could learn what to look for in buying a horse, how to build a beehive, or the ten most useful herbs to improve feline health. And if you ever need to butcher anything, you can consult the diagrams here to ensure you do it correctly.

Cooking: This is far from an exhaustive primer, but there are very detailed sections on a dozen different ingredients, from winter squash to green tomatoes and basic breadmaking. The dairy section is especially useful; people used to know how to make clabbered cream cheese and use a spoonful of yogurt to start another batch, and once you've done either, you'll be hard-pressed to continue buying an inferior product at an inflated price. The section on preserving food is also a great place to start, if you've never done canning or pickling before; there are lots of recipes for simple jams and relishes, vinegars, and (woo-hoo!) a whole section devoted to homebrewing, from hard cider to beer and wine.

Crafts: Try to imagine the exact opposite of the plaques with misspelled, pithy sayings you've seen at craft fairs! All of these goods are useful as well as beautiful, from candlemaking to quilting and basketweaving. In every case, the instructions are comprehensive and clear, and the projects simple enough for a complete novice to attempt. The best section, "Gifts from Nature," features ideas like wreaths, soap and gingerbread houses (think elevations and fretwork details, not graham crackers and Tootsie Rolls). Having long believed that the best gifts are the ones made by hand with love, I couldn't wait to try some of these.

Gardening: In this section you'll learn to grow the plants you'll use for projects all over the book. It begins with a thorough tutorial on types of soil and seed, garden planning and layout and prevention of weeds and pests. Then there are over a hundred pages (roughly a fifth of the book) devoted to individual types and categories of plants, from flowers to herbs, vegetables, roots and fruits. You can find out how to grow the grapes you'll later make into wine; propagate lavender for use in medicinal salves; or transform an existing field into a meadow of wildflowers. Each section contains detailed information about growing conditions, transplanting, maintenance and harvesting.

Health and Well-being: Not to worry, there is no "miracle cure" being promoted here - just the sensible advice of generations who have relied on plants to keep their bodies in balance. There are recipes for bath salts and aromatherapy oils, primers on the care and use of healing herbs like echinacea and goldenseal, and ideas for herbal teas, soups and medicines thought to be beneficial for a variety of ills.

Home: More proof that this book will appeal to both genders! This section runs the gamut from fairly quick (repairs to leaky faucets or broken windows) to very involved (construction of sheds, fences and root cellars.) But both are treated with equal efficiency, and as always, quality and beauty remain important. Ever wanted to learn how to cane a chair, braid a rug or sew a curtain? All are detailed here.

Overall, the best feature of this book is its unpretentious and direct language. No stone is left unturned, no aspect of a project ignored, but the editors have taken care to retain the down-to-earth quality you'd expect from a book based on passed-down knowledge from largely agrarian societies. If you fancy yourself a lover of nature, you will find this book a joy to read for all the years it will take you to do so!
