Nature doesn’t appreciate the bare earth method we call “weeding.” The soil we count on to grow food and flowers isn’t just a blank medium for our use. It’s a fragile, complex, living system that’s home to bacteria, fungi, and other life forms busy beneath our feet.
Left alone, nature brings forth plants of all kinds that improve the soil’s ability to foster life. We call them weeds. They seem to spring up without reason other than to frustrate us. But nature has her reasons.
~Many of these plants boost the presence of mycorrhiza. This beneficial fungi massively improves a plant’s ability to use the soil’s water and nutrients while providing protection from certain pathogens. Mycorrhizas are found in more than 90 percent of plant families but their presence is inhibited by too much fertilizer and can be destroyed by excessive digging, tilling, and soil compaction.
~Many of these plants help to break up heavy soil with strong root systems, aerating and improving drainage. This makes the ground a better home for the plants we prefer to grow.
~Many of these plants improve soil fertility. Two common categories of weeds are dynamic accumulators and nitrogen fixers. Nitrogen fixers are able to capture atmospheric nitrogen, and due to a symbiotic relationship with soil bacteria, these plants “fix” critically important nitrogen in the soil. Dynamic accumulators draw trace elements and other nutrients from deep underground and transport them closer to the surface
In places where soil is poor, the right plants to correct those particular deficiencies tend to spring up. In fact, botanists know that weeds are an indicator of soil properties such as pH and mineral levels. That’s nature’s wisdom at work.
Then we come in, gardeners and farmers, doing our darndest to get down to bare ground between rows of plants. Bare soil isn’t a natural state. The eroding effects of wind, water and sunlight wreak havoc on naked dirt. That’s where weeds pitch in, acting as protective ground cover by holding moisture and preventing topsoil loss. Think of weeds as self-appointed caretakers for vulnerable humus.
Weeds benefit more than the soil.
~In bloom, they attract natural pollinators such as bees, moths, and butterflies. They also provide habitat for many other helpful insects which balance out the pests you don’t want in your garden. Nature likes diversity.
~Plants we call weeds have been used for eons for food, oils, herbs, seasonings, and medications. Might as well celebrate dandelion season by frying up some dandelion flowers or making dandelion lemonade. And during most of the growing season you can pluck some lambsquarters, plantain, purslane, chickweed, or other edible weeds to incorporate in your meals. (Identify them carefully and only pick plants that are not exposed to herbicides.) These foods are highly nutritious, and free for the picking. Weeds are the ultimate way to eat locally.
I want to understand the weeds that nature bestows on me. For example, I’ve learned to respect the fierce tenacity of thistles. Around here they can quickly grow taller than I am. And I can’t help but adore the beauty of those delicate flowers atop such a prickly stem.
They’ve visited most fiercely in our front flower bed, one that was mounded up from subsoil left when our septic system was excavated. Nature knows the soil there isn’t very hospitable to life. That’s exactly why thistles flourished there. I’ve augmented that bed with cow manure dragged from out back, stacked it with layers of straw and mulch, and pulled out as many thistles as I can before my strength gives out.
Thistles are dynamic accumulators that work to bring up deep nutrients and their long roots break up poor soil. Because they’re been actively improving the soil, fewer thistles appear in that bed every year, as if they’re completing a job started nearly 19 years ago. Other weeds are now taking their place, surely just as necessary.
But respect for weeds goes only so far. It’s not possible to grow peas, lettuce, and other delicate plants in a jungle of weeds. Besides, I am a
low energy lazy gardener. Once summer heat rolls in I’m more inclined to hide in the shade with a book than sweat with Puritan righteousness in the sun.
So I have lots of experience with weed control methods. (Other than chemical. I don’t go there.) Here are some thoughts on the matter.
Weeding. I’m not good at pulling weeds either but that’s the method I use most often. As I pull weeds, I lay their still-green bodies between the rows as a natural mulch. I tend to sit on the ground as I hand weed, and I happen to like how close that puts me to the smell of growth and the sight of tiny insects and an overall greater awareness of what’s going on in the garden. The size of my various gardens makes it impossible to do this well unless I want to spend many many hours a week on my butt pulling weeds, which I do until the blazing heat hits. Then I do so fewer hours with greater grumpiness.
Landscape fabric or carpet discards. We were given reams of landscape fabric by a friend of a friend who used to run a greenhouse. It wasn’t easy to get between the rows and batten down with clips, but I covered it with heavy layers of grass clippings and it looked great. I was thrilled. It worked well until I pulled it off at the end of the growing season. The soil looked awful, cracked and strange as if it had boiled under all that black fabric. Rather than being soft and friable it was hard. I wanted to beg the dirt’s forgiveness. I was also rather bitter, as this was easy to use. It also has to be pulled up every year or it’ll accumulate so much biomass on its surface that plants will simply grow on top of it.
Years ago we tried using strips of discarded carpeting. I know, strange, but I read this back in some organic gardening magazine years ago. They claimed that carpet old enough to be torn out of a house doesn’t really have toxins to leach. Carpet kept down 100% of the weeds and, especially if it’s a bright color, gives your garden a Dr. Seuss sort of vibe. It was pretty darn amazing. But again, it has to be pulled up. And like landscape fabric, a great deal of biomass clings to the carpet and ends up being thrown out rather than becoming part of the soil. Worse, I suspect it’s not really all that non-toxic…
Newspapers and straw, or feed bags and straw. I read about the newspaper and straw method many years ago in Mother Earth News, and have been doing it on and off ever since. Basically you layer heavy, overlapping newspaper sections between the rows covered by straw or grass clippings. By the end of the growing season it’s largely biodegraded, becoming dirt by the next spring. I have a love/hate thing going with this method, probably because I’ve made all the mistakes possible. Too little newspaper, straw so flimsy that it doesn’t break into sections that firmly hold anything down. And the worst, trying to put down newspaper when there’s any breeze at all. One year I laid down quite a few rows and got the straw nicely set atop those papers but didn’t dampen it with rain barrel water because the sky threatened rain within minutes. Bad idea. That rain appeared only after heavy gusts of wind, meaning I was running around the yard trying to catch wind borne newspaper and stomping my feet in Rumpelstiltskin fits of frustration.
The past few years I’ve used heavy paper feedbags which are even better than newspapers. We save livestock feed bags and also have our feed mill save us bags. Just cut open, spread out, cover with straw, and water. (Be careful to avoid feedbags with plastic lining! ) Unfortunately our feed mill is using mostly plastic bags, so I’ll be back to newspaper.
Weed whacking. I’ve been hankering after a small weed whacker for some time. I have a dreamy hope that, if I plant rows far enough apart, I can just cut weeds down to a reasonable height. I picture lawn-like strips between rows of gorgeous vegetables. I haven’t tried this yet. Let me add that I have no known weed whacking skills. Chances are I’d accidentally decapitate innocent broccoli plants on my first try.
Thank you weeds. You haven’t forgotten your true value in our teeming, complex ecosystem. As Ralph Waldo Emerson wrote, a weed is simply, “a plant whose virtues have not yet been discovered.”
What do YOU do to live with and live without weeds?

There have been years that I used newspaper and grass clippings on top. I found out that it’s pretty windy here and newspapers blew everywhere and it was difficult to keep moist all the time. The last few years Ive used the root tiller between rows and pick weeds as well, when needed. I love the dirt look, opposed to using tarps or covers around the plants. My husband used to use our old pool cover and cut goes in it for the plants. When I took over the garden I changed that….but it is more work. Good thing that I love to garden!😎

I love weeds, I think they are beautiful, and consider them native plants. Unfortunately, my landlady does not feel the same way.
Thanks for the info. There are a lot of good things here try. Jeans ARE hard to throw away, eh?
I’ve probably been planning that jean quilt for a couple of decades now.

I made a jeans quilt to give as a gift for a new baby, thinking it would be perfect to keep in the car and spread out in the grass at the park. My old machine, a Singer from the late 50’s or early 60’s made it through some really thick seams (I’d preserved pockets and layered stitching for variety) but there was no hope of sewing a binding on. Broke a half dozen needles, gave up and asked a friend with a new machine to help. I’ve now got a small case of sewing machine envy….

Good for you! I think it was the idea of broken needles that kept me from getting around to it. 🙂

I let the weeds grow wild in my front lawn. The grass around it grows tall too, sending down deep roots. Last summer we had a terrible drought, but there remained my lush green lawn without a drop of water, while the neighbors set out sprinklers for hours every day. Mine was also covered in all manner of insects and birds. It was really lovely. But the neighbor across the street who re-sods her lawn every other year, sprays it in chemicals, and pays for a landscaper to come through weekly, she doesn’t like me much. I can’t say what she thinks exactly, but when I don’t mow the lawn, twice a week she sends a teenager to my house to ask if I’d like it mowed. I turn him down politely and there my lawn will sit unmowed again until the dandelions go to seed and the next time a northern wind blows through after that, I mow those dandelions and dance in the cloud of fluff billowing towards my neighbor’s house.

White clover is a great weed to plant on purpose between rows – keeps the other weeds down, enriches the soil and doesn’t complain too much about being walked on. Also it has a taproot so before it starts sending out runners you can just flick it off with the hoe and turn it upside down, and let it mulch in. Watch out for those denim quilts, if you ever have to wash it you’ll need 3 people to help get it out of the washing machine – they weigh a ton 🙂
