Few pursuits are as rewarding as growing your own organic garden. Not only do you get to enjoy the fruits of your own labor, but you have the satisfaction of knowing that the produce you are eating was grown free of chemicals, pesticides and herbicides. Growing organically produces healthy, more diverse ecosystems which are better able to resist significant pest damage… naturally!
That so-good-for-you vegetable — broccoli — is in the news. A “dream team” of botanists, agrarians, and marketers has come together at Cornell University to create a broccoli that will grow in areas where the heat-sensitive cruciferous won’t normally grow. And therein lies the problem. Since nearly all commercial broccoli is grown in California, the plant suffers days of transportation before its delivered to midwestern, southern and eastern markets, a time that saps the broccoli of its fresh taste and snap. The new hybridized broccoli can withstand the relative evening warmth and humidity that has made successful commercial farming of broccoli east of the Rocky Mountains difficult. The New York Times has the story.
The piece is actually a double profile of both broccoli and the plant physiologist who fronts the broccoli effort, Dr. Thomas Bjorkman. Bjorkman, himself a vegetarian, has envisioned making broccoli more readily available in American markets. He’s also sought to make it more palatable and nutritious. Apparently he’s succeeded. The new hybrid broccoli contains more glucoraphanin, a compound that’s been found to prevent cancer. (more…)
We’ve talked a lot about xeric landscapes, water-wise gardening, drought-tolerant plants, and the like, all good things. Conserving water is always a good thing, especially when you’re paying for it. But there’s one place where skimping on garden watering can have bad consequences, where thirty plants will drink up water more quickly than anywhere else and that’s your vegetable garden. Let’s face it. Vegetables are water intensive. It takes 16 gallons to grow a single head of lettuce. It’s estimated that 40% of all water use in the United Stages goes to growing food.
So while vegetable gardens will drink up more water than your thyme and lavender-planted rock garden or you native grass lawn, it’s water well spent. But that doesn’t mean you can’t conserve water while growing vegetables. Here’s some tips, gathered from a variety of sources to help you save water when you’re giving your vegetables what they need. Most of these techniques are second nature for experienced gardeners. But they bare repeating. (more…)
It’s July and, as the song goes, the living is easy. Sure there are little chores to be done — watering, of course; and weeding — but mostly this is an expectant time with bountiful harvest of greens, peas (if you live where it’s not too hot), and fast growing root vegetables. Summer squash are in blossom and maybe setting fruit, corn is knee-high and higher, and winter squash, cucumbers and other vine crops are showing some muscle and starting to take over. There’s the first tomato blossom and is that the first tiny bean forming among all those blossoms?
It’s a good week to spend time with your garden doing nothing but taking stock. How is your garden plan looking now that things are well on their way? What pest problems are you having? How does the weather look for the rest of the month? Mostly, we just like to sit back and look at the fruits of our work. Things are still neat and orderly, everything is robust and green. And then we start thinking deeper (gardens will do that to you). Where did the craft of doing this come into our lives? How is it that with each passing year we learn more and more about raising vegetables? How well are we doing passing our knowledge to children and friends? And how important are those friends and children to what we do and learn? (more…)
After our last column, a friend pointed out that she didn’t have trouble getting melons to pollinate. Her problem was with blights and mildew. It’s true that melons are a bit difficult to grow because of their susceptibility to molds and certain insects, especially when you’re trying to grow them in cooler, damp climates. Any trouble growing melons is well worth it once they reach the table. The cantaloupes, watermelons and other melons now coming into our stores from warmer climates just don’t hold a candle to a juicy, sweet, homegrown melon.
Finding the proper natural or organic cures for these melon problems can be difficult. Mulching is great for issues caused by uneven watering. But mulch can provide places for pests including squash bugs and cucumber beetles to lay eggs. These pesky critters not only consume melon plants but spread disease and wilt. Melon leaves can be burned by insecticidal soap and liquid copper sprays, two common, organic-approved solutions for bugs and mildew. They should only be used in the most diluted form possible. Other problem solvers — like using row covers to shield plants from insects — are great ideas until you need the help of pollinators. Any successful melon growing regimen begins even before you start them in your garden. (more…)
How to hand pollinate plants in the vegetable garden.
No, it’s not the latest dance craze. It’s what certain plants in your vegetable garden need to set fruit: a good shaking. Yes, it has to do with sex, er, pollination and plants can sometimes use a little help. But what it really has to do with is better yields come harvest time. So let’s get ready to pollinate!
Not a year goes by when we don’t hear someone complain that their tomatoes, cucumbers, or squash didn’t set fruit. Oh, the plants grew like crazy and blossomed to beat the band but when it came time to produce? Little or no fruiting occurred. We’ve even had this happen ourselves, usually after relocating to a different part of the country. When we’re asked what went wrong, we realize (doh!) that we didn’t do what needed to be done, that’s when we remember hand pollination. Now that July has arrived and gardens around the country are beginning to flower, it’s time to pollinate. (For those of you in cooler climates or whose gardens might be a bit behind schedule this year, here’s hoping that your blossoms are soon to show.) (more…)
In an effort to reduce water use and time spent caring for lawns, some gardeners are replacing their turf with thyme. Thyme is an ideal grass alternative. It requires less water, is generally tough (see “walking on thyme” below), drought resistant, hardy all the way north to zone 4 if it’s healthy, and will spread easily to fill in most of the space that you want it to. Best thing: it becomes a carpet of attractive, lavender-colored flowers that lasts long into the season. If you’re looking to replace your thirsty grass with something more xeric, consider thyme.
There are down-sides to putting in a thyme lawn. It can be expensive. When you’re planting plugs of thyme 6 to 12 inches apart, you can burn up a lot of cash fast. Most sources recommend planting smaller areas. If you have a croquet court-sized yard (in other words, large) you might want to consider planting only part of it in thyme to start. You can always go back and expand your thyme planting another season. The other down-side is the labor it takes to get your thyme in the ground. You’ll need to kill off all the grass where you intend to plant first. This can be a slow and difficult process.
How to do it? The easiest way is to use multiple applications of Roundup. But you’re not in this for easy, you’re in it to protect yourself, your loved ones, and the environment at large from harmful sprays. Digging it up is a poison-less way to do it but a lot of work. You can’t just yank up sod, leaving behind roots that will result in another layer of grass popping up. If you do dig — say you have a small space that will be manageable — dig deeply and make sure you remove any trace of roots. (more…)
Companion plants for tomatoes — not always a perfect pair!
Last evening, your friendly and inquisitive Planet Natural Blogger visited a couple of distinguished food writers — they are a couple and have a couple James Beard Awards to their credit — to get their opinions on some local barbecue for a story I’m writing. We ate outdoors in their beautiful patio garden, their chickens serenading us from the nearby coop that was just out of sight.
Their garden is incorporated into the modest outdoor living space. A pair of cherry trees, their growing space circled in rock, is at the center of the stone patio (no cherries this year; a late frost took all the blossoms). Around the first cherry tree were various flowering plants. Only the bleeding hearts were in bloom. The earth around the second tree hosted a variety of herbs, partly shaded, that were just reaching picking size. One of those herbs was basil.
Elsewhere, beans, cucumbers and tomatoes were growing on terraced steps in full sun near the walls of their white-washed adobe house. By the house’s entrance, among several other plants and close to some lettuce that was already past its prime, was a yellow pear tomato plant already holding some blossoms. The space, with its various pots, growing areas, and walking spaces, not to mention the table where we sat enjoying ribs and brisket, seemed well designed. But I was puzzled by one thing. Knowing that tomatoes and basil, both full-sun lovers, did so well together, I wondered why they weren’t growing side-by-side. “We tried that,” one of my friends said, “and it just didn’t work.” (more…)
We’ve been intrigued lately how the practices of sustainable, organic gardening and permaculture integrate composting into their philosophies. Your friendly Planet Natural Blogger has been known to say that organic gardening and specifically composting will save the world and both those endeavors seem to prove it. Yet, both have their differences.
We won’t go into all 12 principles of permaculture here. But consider how many of them are addressed by composting (as listed in Christopher Shein’s excellent new book The Vegetable Gardner’s Guide To Permaculture): work with nature, produce no waste, use and value resources, catch and store energy. To organic gardeners, all that come together to mean one thing: improve soil conditions without harmful chemicals.
This is the time of year we’re adding grass clippings, if we have them, to our compost piles as well as vegetable scraps from our kitchens, thinnings from our garden (if we’re not eating them), and year-round items like cardboard and newspaper. The permaculturist, in an effort to diminish waste, advocates using shredded office paper and the like as a brown (carbon-heavy) material. The organic gardening purist may not want to add newspaper because of what might be in the inks, office paper because of the bleaching agents that make it white, and carboard because of the glues used to hold its corrugated surfaces together.

“She loves me… she loves me not.” Whichever way the petals fall, one thing is certain. We all love daisies. When other flowers are fading away in late summer, daisies stand long and tall, gracing our landscapes with abundant blossoms. Even those of us who’ve seen them invade our lawn and realized how hard the hardy plants were to get rid of love some kind of daisy, even if we hate those particular (usually hybrid) daisies.
The kinds of flowers commonly called daisies are actually a smaller group than what’s in the daisy or asteracae (aster) family. That large group that counts some 600 species includes sunflowers as well as daisies, cone flowers, and asters. Our personal favorites are the tiny alpine daisies that grow above timber in the highest mountain passes. Here in the southwest, annual African daisies are popular for their varied colors and drought resistance. What’s known as the New England daisy or aster — and this is one of the great things about daisies — actually grows all across the country. (more…)
As many parts of the country move into the dry season (some parts are already there; others have the opposite problem), it’s a good time to consider xeriscaping principles in our gardens and landscapes.
What is xeriscaping? Simply stated, it’s water-wise gardening. It’s not just about the water we use (or don’t) during times of drought. It also addresses our use of diminishing water supplies as demand — from population and housing growth, agriculture, industry (especially the natural gas industry) and, yes, drought — continue to tax finite water supplies. Xeriscaping is a way of continuing to have enjoyable landscapes in the face of less and more expensive water use.
The details of xeriscaping are encyclopedic. They’re linked to local soil, native plant, and climactic factors. But the basic principles are simple, common-sense measures and are easy to apply almost anywhere. Here are the eight principles, with our comments, listed in David Salman and Cindy Bellinger’s aptly titled and useful reference Waterwise Garden Care: Your Practical Guide published by High Country Gardens Publications.
