As water bills skyrocket, as more gardeners move to semi-arid locations and drought becomes a persistent problem, growers of all sorts want to know: what’s the most efficient way to conserve precious water? Xeriscaping — “scape” comes from landscape and xeros, in Greek, means “dry” — is the practice of smart, sustainable water use. Techniques discussed here include wise-watering methods, rain gathering, choosing condition-tolerant plants, soil improvement, mulching — anything that results in the effective use of a valuable resource.
Tips for using less water when city restrictions demand it.
The drought, widespread and persistent, continues across great swaths of the United States. The effects of climate change and heavy demands on water use have seen formerly reliable supplies dwindle. Cities and counties across the nation, from Williams, Arizona (natch) to Mount Pleasant, Tennessee, from the St. Johns River district in north central Florida to Chanhassen, Minnesota and all across California have put water use and watering restrictions in place. What’s their most frequent target? Watering of lawns.
We’ve frequently considered the water spent on lawns and have advocated replacing them with native grasses or something altogether different. But let’s face it. Kids like lawns, dogs like lawns, and we like lawns too for family activities. We’ll cut back on lawn as the kids grow up. But for now . . . badminton! (more…)
Make sure your plants don’t receive too little or too much water.
Though it’s not true everywhere — the forecast today for Bozeman includes a 40% chance of scattered showers — we’re fast approaching that time of the growing season when your garden, lawns and flower beds included, need to be closely monitored for moisture. How do we know when our plants aren’t getting enough water? They tell us.
Water stress is the term used to denote any moisture-related problems that plants might have. This includes too much water as well as too little. Water stress can also be caused by the quality of the water given to the plants. Water containing too many dissolved salts or grey (recycled) water that contains pollutants can also stress plants. (Phosphorous, found in many home detergents and soaps, can actually aid plant growth if proper amounts aren’t exceeded… Tip: use natural cleaning products.)
As every gardener knows, determining when plants need water is easy: their leaves wilt. But of course, you don’t want to get to this point. When you spot wilting, you’ve already stressed your plant. (more…)
We don’t have to tell you. The news from many parts of the west is all about drought. You can find accounts of what’s being faced, including the potential for cutbacks and rationing, here, here, and here. And the forecast for the coming months doesn’t look good.
No matter if you believe that drought is just a part of the natural cycle (it is) or is a product of global warming (we don’t see this as an easy either-or question but think both factors could be in play), dealing with a lack of or more expensive water is something that gardeners frequently face. Even as a back-to-the-land, ex-hippie in the 19(garbled) living on the edge of the rain forest in Washington State we had summer months without rain some years that meant the buried reservoir that collected water from our spring filled more slowly and even ran dry when we watered our rather large garden. That’s the problem with water: you run out just when you need it most. (more…)
– In Europe, the number of scientists and other experts contesting EU chief science adviser Anne Glover’s statement that genetically modified foods are no less risky than conventional, natural grown foods continues to grow. Over 275 specialists have signed a document that states that GM foods have not been proven safe and that existing research raises concerns, according to GM Watch, a European organization that monitors and reports on issues relating to genetically manipulated food sources.
Dr Angelika Hilbeck, chair of the European Network of Scientists for Social and Environmental Responsibility (ENSSER), which published the statement, told GM Watch, “We’re surprised and pleased by the strong support for the statement. It seems to have tapped into a deep concern in the global scientific community that the name of science is being misused to make misleading claims about the safety of GM technology.” (more…)
Now that our lawns, garden plots, and everything else is covered in a blanket of snow — a blank slate of sorts — we start to think about how we want them to look next spring and summer. What we’re picturing during this dose of dead-of-winter-in-late-fall weather is grass, not the kind that comes in rolled strips and requires mowing and lots of water. We’re thinking of bold, unique grasses that require far less watering and no mowing whatsoever (though we might be trimming them back in the late fall or winter).
Why are we thinking grasses? For the reasons already stated. They need less water than a lawn and less care. They’re much more adaptable to organic growing without chemical fertilizers. (more…)
Don’t get us wrong. We love mulches of all sorts. But one kind of mulch we’ve seen too much of is beauty bark. You know what we’re talking about. That chipped or shredded bark often bought in bags, sometimes sold in bulk, that’s used to cover bare ground around trees, in various landscape beds, and other open space. It’s become a suburban American cliche.
The stuff can often be attractive, sure; and give off a delicate scent, especially if it contains cedar. It does what mulch is supposed to do: keep down weeds, slow moisture evaporation, prevent run-off from heavy rain. And it does break down and add organic matter to your soil. (more…)
Xeric and natural landscapes ask, “What is a garden for?”
Beauty is in the eye of the beholder. That well-manicured lawn with its precisely-trimmed shrubs and hedges may look okay around an old-money McMansion, but is that what you want in your open space? With water-wise planting, conversion of labor-and-liquid-intensive lawns, and utilization of native plants, many of us are providing new answers to an old question: What is a garden for?
James Golden’s garden in a cleared patch of woods above the Delaware River in New Jersey is, as he says, good for nothing. But he doesn’t really mean it. His acreage is a jumble of native and exotic plannings, a sort of living collage constructed of many pieces, each having their own interest, but assembling into one attractive whole. (more…)
This is the time of year that your flower beds can start to look a little weary. You had beautiful blooms from late spring through the first weeks of July but now, in the heat, summer flowers are starting to fade. You can dead head all you want — this will keep some plants blooming into fall (one of the reasons we love marigolds) — but most flowers don’t want to make the effort once things turn hot and dry.
Still, there are ways — and plants, both annuals and perennials — that will keep color in your flower gardens well into fall. Like most things in the garden, they require some advance planning. If you’ve started seeds well into the season indoors, and chosen those seeds wisely, then you may have late-blooming annuals that will keep your landscape alive with color. Late blooming is just one of the traits we’re looking for. Drought tolerance, the ability to adapt to xeric conditions, is another. You may think that starting annuals to put out later in summer is a lot of work for little return. You might change your mind when you’re enjoying blossoms on labor day. Perennials, well, your return on investment will accrue season after season.
Of course your local conditions will determine which plants are best for late season color. This is where a good local garden reference, either online, through a university extension division or, most likely, at your friendly neighborhood nursery, comes in handy. The nursery is also the place to get late blooming plants in case you didn’t have the luxury (or go to the work) of starting flower seed for late planting. (more…)
Our correspondent in Santa Fe, New Mexico writes in about the city’s new botanical garden, a combination of artful design and water-wise planting:

After several years of work and planning (and fundraising), Santa Fe’s new botanical garden, located on Museum Hill in the city’s high-and-dry southeast section, is about to open its first phase. Designed by renowned landscape architect and artist W. Gary Smith, this orchard garden phase incorporates artistic design of the sort Smith is known for even as it employs an emphasis on water conservation. (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…)
