We all know the nutrients — nitrogen, phosphorous, potassium, magnesium, calcium, sulfur — that are important to plant health. We call them macronutrients. But there’s a whole list of micronutrients that are also key, in much smaller quantities, to the health of your plants. These plant micronutrients — boron, iron, zinc and others — not only assure healthy growth, they help your gardens fight off pests and diseases.
The best long term way to keep your garden soil rich with the micronutrients it needs is by adding compost. The living things that go into compost — grass clippings, leaves, plants trimmings — already contain various amounts of micronutrients. Their presence in your compost guarantees that you’re returning those micronutrients to the soil.
But what if you can tell (PDF), because of yellow leaves or other signs of weakness (or from you extension services soil test), that your soil is deficient in micronutrients? Your plants are well on their way and it’s too late to effectively amend the soil. What can be done to give them a quick boost full of the micronutrients they need? (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…)
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. (more…)
“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.

Yes, it is possible to get rid of dandelions without using toxic sprays. Here’s how:
Your friendly Planet Natural Blogger has been taken to task for saying organic gardening is no harder and maybe even easier than conventional gardening. This came while addressing vegetable gardening and the context was that eventually you may have less weeding, less watering, and less problems with insects after you’ve been using organic practice for a while. The criticism came using one work-intensive example: getting rid of dandelions without using chemical sprays.
Our critical friend has a point. It’s so much easier getting rid of dandelions with Roundup or other herbicides that are designed to penetrate the length of the dandelion’s long tap root. But then you have a frightful chemical, one that’s been shown to put embryonic and kidney cells at risk, lingering in your soil. The other problem with these kinds of herbicides: they don’t stop new seed, which may have blown in from far away, from germinating. Once a new dandelion plant starts growing in your yard, it’s time to spray again. And Again. And… well, you get the picture. (more…)
Reading through Danny L. Barney’s new book Storey’s Guide To Growing Organic Orchard Fruits (Storey Publishing) not only got us to thinking about what it takes to grow apples, pears, cherries and other fruits without chemical sprays, but also, like a lot of things, made us nostalgic.
Your sentimental, fruit-crazy Planet Natural Blogger grew up on a small orchard back in Nebraska that was sprayed heavily every year. My father was in the pest control business and had access to the compounds and equipment. I remember him fogging the whole place in an effort to keep the mosquitoes and other insects down. Insects weren’t the problem, and needless to say the sprays did nothing to alleviate our real problem, blight and blemishes (and we still ended up with mosquitoes anyway). He didn’t wear a mask or respirator when doing this and neither did we. But we loved to run through the fog much to his chagrin (Note: Dad’s long gone but we’re still healthy).
Maybe it was in reaction to this that — like a lot of former hippies — when we took to the land, we adopted an organic lifestyle. Those of us old enough to remember the Alar apple scare of 1989 probably aren’t surprised to know that the conventionally-grown fruits we buy are still tainted with harmful substances. Some of these chemicals are especially bad for children. (more…)
So you didn’t aerate the lawn last fall … and it needed it? It’s not too late in most parts of the country to aerate your organic lawn. And, if your lawn’s not organic, now’s the perfect time to begin converting it. And aerating is a big part of the change.
- Why aerate? Your lawn may suffer from compaction, especially if you and your family are on it a lot (and you should be… why else would you have one?). Many of the lawn problems we blame on insects, lack of water, and poor fertilizer are actually due to compaction. The more your soil is compacted, the more likely you are to have problems with thatch. When you aerate – or “aerify” as my gardening dictionary calls it – you allow more oxygen into your soil, you help prevent run-off, and you break up grass roots, further encouraging them to grow. And you do it all without harmful chemical fertilizers! (more…)
