It’s no secret. I’m not a gardening diva.
And heaven knows I’ve had my share of ridiculous gardening mistakes, like that time I killed my whole garden with poisoned hay mulch.
Even so, I stick with it every year. Every January, I order my heirloom seeds and dream of that idyllic garden that weeds itself and never looks messy. (Are you laughing yet? ?) And then, by June, the weeds are working hard to destroy the dream. In fact, the weeds—and freak hail storms in July (yeah, that happened this month– the lovely picture at the top of this post happened just SIX HOURS before it hit…)—can be the most stressful part of gardening.
I use natural weed control ideas in my garden because, who wants to use chemical sprays on an organic garden? Especially since I worked so hard to grow my garden from seeds (despite summer hail). I’ll never completely eradicate the weeds, but I’m okay with that.
Is there a fool-proof way to permanently banish weeds? No. At least, I’ve yet to find it… But these natural weed control tips I’ve learned over the years will help you enjoy your garden more.
Natural Weed Control for Your Garden
1. Smother weeds
Mulch has always been my best friend in waging the war on weeds, whether it’s old straw, grass clippings (make sure the lawn has not been sprayed with anything), or raked leaves.
If you are a long-time reader, you are probably well-acquainted with my foray into the world of deep mulch using hay, which started magnificently, and then ended tragically.
If your weed layer is especially stubborn you can also try stunting it by applying a layer of cardboard or newspaper before you add organic mulch. This is a bit more hardcore in smothering the weeds and will keep them repressed.
And bonus—mulch serves a dual purpose. While it keeps weeds out, it keeps moisture in. Of course, none of this matters if you still wind up killing your garden with chemicals, so make sure you know where your mulch comes from and ask if it’s been treated with chemicals. If you’re going to a local farmer for hay to use as mulch, make sure you ask how he fertilizes and sprays his fields.
Another smothering system I’ve heard of is called “solarization,” which lets the sun’s heat do all the work over the course of a season. To solarize the soil, you would simply put heavy plastic or tarps on the weedy area, weigh it down with bricks or other heavy weights, and let the sun bake the weeds. The downfall to solarization is that it can take many months to complete the process (especially if you are attempting it in winter or you live in a cooler, northern climate).
Also, solarization is non-discriminating, so it will also kill off good organisms in your soil, so use it sparingly.
2. Water wisely
Just like your lovely vegetable plants, weeds love to be watered. Because a sprinkler system is indiscriminate, watering individual plants directly keeps the life-giving water focused on your food.
Drip irrigation and soaker hoses are great choices that focus the water right where you need it, effectively prevent healthy weeds, and save water to boot. I love win-win-win.
In my raised bed garden, I apply this concept by carefully adjusting the mini-sprinklers in the beds to avoid overspray and keep the water contained within the bed and not on the walkways. As the heat of summer increases, the weeds start to feel the burn from lack of water and it definitely reduces their vigor.
3. Plant thickly
One great way to keep weeds from spreading? Refuse to give them any squatter’s rights. Obviously, the less empty space you have in your garden, the less space the weeds have to put down roots. Whenever possible, squeeze more plants in your growing space, keeping the soil covered with good plants (and, another win-win, more food!).
I see this working especially well with my potato and cabbage beds– I tend to crowd my plants in these areas and while I do have to weed normally while the plants grow, eventually they take over the beds and the weeds are discouraged.
If your plants need lots of growing space (like those crazy tomatoes that are always stretching their limbs), try keeping the excess space protected with a traditional mulch (I’ve been using our grass clippings this year with great results) or a living mulch, like buckwheat.
4. Pull ‘em when they’re young
Even when I do all of the above, weeds still find a way to show up all over my garden beds and paths. But I find there is a definite window of time that it’s super easy to deny them long-term living space. If I boot them out when they’re young and small, I find it’s much easier to control them overall. If I don’t get them when they’re baby weeds, it seems like almost overnight they’ve gone to seed or grown intense roots systems, which are much harder to pull.
And never, ever, ever let those weeds go to seed… Otherwise they’ll haunt you for years to come.
With particularly stubborn weeds that I CANNOT remove by the roots, no matter how I hard I try, I’m using the EXHAUST method.
Take yellow dock for example… I have several patches of this in my garden that WILL NOT go away, even though I’ve built raised beds on top of it and smothered it with landscape fabric and wood chip mulch. The roots go down to China, so I’ve given up trying to dig it out. However, as soon as I see a fresh crop of leaves appear on it (usually overnight because that plant is stinkin’ tough…) I chop ’em off to avoid the plant getting any photosynthesis action. Over the past few months, I’ve noticed the plant loosing it’s ‘oomph’ and I’m going to keep exhausting its resources until it gives up.
5. Make Homemade Weed Killer
Okay, so while numbers 1-4 sound great, life can get busy. And weeds seem to get the best of us. Every year. This is where my homemade weed-killer spray takes center stage. But I have to come clean here. It’s nothing fancy. In fact, it’s just one ingredient. And you have some right in your kitchen pantry.
My secret homemade weed-killer spray? Vinegar. I pour vinegar into a spray bottle and spray it directly on the weeds. I soak them well and I wait until it’s a scorcher, dry day. I also prefer a non-windy day, and I’m ultra careful to not let the mist touch my good plants. Because, of course, vinegar doesn’t know how to distinguish my weeds from my peppers. 😉
Two Important Notes About Using Homemade Vinegar Weed Killer for Natural Weed Control:
- I don’t use my homemade vinegar weed killer in or near my garden beds— it’s too risky that it’ll get on my veggie plants. However, it’s a fantastic option for walkways or in your driveway where the weeds just won’t quit
- You can use a super-strength vinegar (also called horticultural vinegar) for this, but it’s more expensive and tougher to find. So unless you have a ready supply, just grab a gallon or two of regular, 5% cheap white vinegar from the grocery store.
I guess this is a good place to mention another weed remedy that everyone has in their kitchen. Believe it or not, boiling water is a detriment to weeds. Just dump it on. That’s it. I don’t recommend this for all your weeds, but if you have a full pot full of blazing hot water after canning, you can carefully carry it outside and pour on the annoying weeds popping up through the cracks in your sidewalk. (Just don’t splash it on your toes!)
6. Give Up And Eat Your Weeds
Now that I’ve spent this whole post bemoaning weeds, I will say that some weeds can serve us well and I’m not completely anti-weed. (Just yellow dock and bindweed… They are my sworn enemies…)
I highly recommend identifying the most prevalent weeds that grow well in your garden and researching if they have a good purpose. You might wind up sparing the lives of a few that you can use for a wide range of purposes.
Some weeds actually have beneficial uses either for your health, as a food, or they can be useful for beneficial insects. Clover, for example, can release beneficial nitrogen into the soil. It is also a favorite food for bees.
Sometimes, I like to see these useful weeds as just bonus produce in the garden. Produce that I did not have to carefully raise from seed. This positive spin on weeds won’t work for all types of weeds, but it can help you find certain types of weeds as useful instead of annoying.

Final Advice on Making Natural Weed Control Work…
My BEST tip for effective natural weed control? It’s really true for all of life… slow and steady wins the race, guys. When I weed my garden every day for just 5-10 minutes a day, I find I have much more control over those invasive plants.
Mind you, I don’t follow my own advice all the time. Sometimes I do put off weeding. Then it’s bad and I put it off more. Then I spend all day on the defense in the war against weeds, and wind up grouchy and sore. I’m much happier on those months that I act like a gardening tortoise… slow and steady, Jill… slow and steady…
