How To: Weed Your Garden

While you may not be able to eliminate weeds entirely, you can certainly keep them in check by following some basic techniques.

Even late into the season, the summer can seem like one prolonged fight against garden weeds. The bad news? There’s no winning this war; you’ll be engaged on the front lines so long as you wish to maintain a manicured landscape. But with the right tools and proper techniques, you can keep the enemy contained.

Preventing weeds is the best way to limit their proliferation. The basic strategy here is to make your garden a less-than-hospitable location for unwanted plants. First and foremost, limit the amount of bare soil present in your garden, as empty patches of fertile soil are like oases for weeds. Instead, plant densely, use mulch, and consider taking advantage of the natural weed-suppressing power of ground covers or landscaping fabric, the latter being effective but artificial.

Even the best practices won’t stop every single weed from finding its way into your garden, but by employing some or all of the following methods, you can stand your ground against their ceaseless incursion.

1. Weed daily
Some gardeners weed only once a week, and surprising though it may be, even that frequency gives the roots of weeds sufficient time to grow deep and strong. A superior strategy is to weed a little every day. That way, you ensure the problem never gets out of hand. Bring along a kneeler and a shovel, a weed knife, or even an old fork to help you get to the roots. Don’t neglect walking rows (footpaths between plantings); if weeds get a stronghold there, they can easily spread.

Note: If you weed more frequently and vigorously in the first months of spring and summer, you’ll be doing yourself a favor for the rest of the growing season, as you’ll prevent weeds from going to seed and spreading farther afield.

2. Hoe regularly
Another way of uprooting weeds is to hoe regularly. Gardeners favor this approach, as it allows them to avoid the backbreaking work of pulling each weed manually. Be very careful not to hoe too deep, though: You might bring weed seeds to the surface, where they will enjoy access to the light and water essential for growth. Once a week, stir the soil at the base of plants to a depth of three inches maximum. Hoe only to one inch if you want to stay on the safe side.

3. Pull, don’t yank
Take care to remove the roots of a weed so that it doesn’t return. Yank out a weed too quickly and it might break, with the result that you pull out the top but not the all-important root system. For best results, pull very gently (if the soil is soft) or use a tool to dig it up (if the soil is hard). If digging, do so sparingly; you don’t want to disturb the roots of the plants you wish to keep.

4. Choose the right time
Don’t weed when the soil is soggy, but do weed when the soil is wet. It’s easier to pull the roots up out of damp soil. Save hoeing for days when the ground is dry.

5. Get ’em out of there
Once you’ve pulled out a weed, don’t let it sit around on bare soil. Its seeds could find their way back into the ground. Let pulled weeds dry out and die in the sun, preferably on the sidewalk, then either throw them away or into a compost heap.

Note: Do not compost weeds that have gone to seed. That’s a recipe for getting more weeds when you ultimately return the compost to your garden.

6. Chop off their heads
If weeds have grown so big that you aren’t able to fully uproot them—or if they are so close to other plants that to remove the root of the weed would mean risking the roots of the plants you want to keep—then chop off the heads of the weeds. This will kill them slowly and prevent them from going to seed and spreading further. You may have to chop multiple times, but eventually they’ll die out.

7. What about herbicides?
Herbicides usually require many applications, as they (literally) fail to address the “root” of the problem. Be careful: They can be toxic to pets, children, and other plants. Use sparingly, or experiment with organic herbicides, such as vinegar or boiling water. In all cases, make sure you’re spraying or pouring herbicide only on weeds, not inadvertently killing other plants in the process.

Wondering how to weed your garden? While you may be unable to eliminate weeds entirely, these basic techniques can certainly help you keep weeds in check.

8 Things to Know When Pulling Weeds

Banish weeds the right way—and keep them from coming back—with these tips, tools, and techniques.

Ask any group of gardeners to cite their least favorite task is and you’re bound to hear a chorus of “Weeding!” Rampant weeds steal water and valuable nutrients from the soil that beneficial plants could be receiving, and their less-than-lovely heads detract from lawn and garden design.

In your quest to keep your landscape weed-free, it’s easy to make some overzealous mistakes. Before you begin pulling weeds, read on for the right way to vanquish green invaders and reduce their future growth. Your bountiful vegetable harvest and big beautiful flowers will thank you!

1. Don’t wait to weed.

If you let weeds tower over your tomatoes, you’ll have a tough time getting them out. When weeds are small, their roots are weaker, making it easier to pull them out. Commit to doing a quick walk-through of your garden every other day; it will take only a few minutes to pull up any young weeds that show up.

Bonus tip: Pull weeds soon after watering your plants or a rain shower; when the soil is moist, the whole weed is more likely to come out by the roots. It’s perfectly fine to put pulled weeds in your compost bin, where the naturally hot temperature will destroy any seeds.

2. Grab by the base.

Gardeners who weed manually may be tempted to reach down and snatch a handful give it a sharp tug. Unfortunately, that often causes the weed to snap in two, leaving the bottom half and the roots still in the ground. Instead, take your time and grab each weed individually at its base and then pull slowly and steadily to ease the roots from the soil.

3. Ply the proper tools.

Many gardeners find that a few tools make weeding speedier. Choose well-made implements with a solid handle that feels comfortable in your grasp and a head or blade made of tough forged steel. Also, select tools that suit your weeding method, either kneeling or standing.

Kneeling tools: These have relatively short handles, from about six to 12 inches long. Rake-type tools with finger-like prongs (such as the Gardener’s Claw Rake, available on Amazon) work well for scraping up surface weeds with minimal root systems, such as henbit. A hook neck tool (such as the CobraHead Weeder, available on Amazon) can be positioned behind the base of a weed and used to dig in and scoop out the intruder. To remove weeds between beneficial plants, try an angled hand hoe like the Nejiri Gama Hoe (also available on Amazon), which features a sharp point for getting into tight spots. Hand shovels can be used to dig out large weed roots.

Standing tools: For removing many weeds at once, it’s hard to beat the tried-and-true long-handled hoe, but today’s manufacturers have done just that! A hoe with a sharpened blade, such as the ProHoe Rogue Garden Hoe (available on Amazon), can sever roots beneath the soil surface with a single chop. Grip-and-pull weeders like Fiskars’ Deluxe Stand-up Weeder (available on Amazon) promise to save time and labor when removing weeds with deep root systems, such as dandelions. Sharp prongs are driven deep into the soil by pressing a foot pedal, and then the prongs grip the roots securely and pull them right out.

4. Understand herbicides.

Need a break from the strenuous work of pulling weeds? Controlling these unwanted crops with foliar herbicides (toxic substances absorbed through a plant’s leaves) is physically easier than either pulling or hoeing. Just be sure to consider the pros and cons of these weed killers before you go this route.

PROS

+ Spraying a foliar herbicide such as Roundup (available on Amazon) effectively kills individual weeds or large areas that are awash with weeds.

+ Foliar herbicides work fast, killing weeds sometimes within a day—and usually no longer than a week—of application.

+ There’s no need to remove weeds individually and no strain on your back from bending over and pulling weeds for long periods of time. After the weeds turn brown and die, rake them into a pile and dispose of them.

CONS

The wind could blow herbicidal spray onto beneficial plants, inadvertently harming or killing them.

Exposure to chemical herbicides may result in skin irritation while inhaling the spray can result in a sore throat and other respiratory woes. Care should always be taken not to come into contact with the spray.

Weeds that are chemically killed should not be placed in the compost bin. Traces of herbicides can survive the composting process and may result in stunting vegetation if later used in garden soil.

Chemical herbicides may interfere with the environment and studies indicate that the chemicals can affect earthworms and offset soil nutrients, leading to the leaching of chemicals into streams and underground aquifers. Consider a non-toxic herbicide, such as A.D.I.O.S Eco-Friendly Weed Control (available on Amazon), which will allow you to avoid the contamination problems associated with toxic herbicides.

5. Avoid pulling weeds with an ounce of prevention.

You don’t have to kill or pull weeds if they don’t grow in the first place, so consider a pre-emergent to keep weed seeds from germinating. Sprinkle a granular pre-emergent herbicide such as Preen’s Organic Vegetable Garden Weed Preventer (available on Amazon) on the soil and then water. The granules will dissolve and permeate the soil, creating a barrier around the weed seeds. A single application will last up to 12 weeks, after which the product can be reapplied.

Note that once a pre-emergent is in the soil, beneficial seeds won’t sprout either. For best results, wait until beneficial plants are four to eight inches tall before using a pre-emergent product (as directed on the package)—it won’t kill plants that are already growing.

6. Cut it out.

Some stubborn weeds, such as Canadian thistle, not only send deep roots that are extremely hard to pull, but also feature prickly stems and foliage that will pierce anything less than heavy leather gloves. When dealing with these tough customers, reach for a sharp pair of nippers, such as TABOR TOOLS Bypass Pruning Shears (available on Amazon) for small to medium size weeds or long-handled shears, such as Fiskars 28” Bypass Loppers (available on Amazon) for cutting down those large Canadian thistles. The roots will still remain in the soil, but in most cases, if you remove the entire growing part of the plant, it can no longer receive the sunshine it needs to survive.

7. Know when to turn up the heat!

If you find yourself with a large swath of weeds that don’t respond to other methods, consider burning them out. A weed burner, such as the Red Dragon Weed Torch Kit (available on Amazon), connects to a standard propane tank to deliver a flame directly to the weeds, scorching and killing them. A weed burner works well on invaders growing beneath fences or encroaching near raised garden beds. Be sure weeds are green, not brown and dry. You want to scorch them, not start a fire. Check with local authorities before using a weed torch as some communities may restrict or ban their use.

Hot water can also kill weeds. Carefully pour a pitcher of just-boiled water directly on weeds or use a steam weeder, such as the DynaSteam Weeder (available at Amazon), to simplify the process—and reduce the risk of dripping scalding water on your feet.

You can also use heat to kill weeds between gardening seasons. After harvest, cover a planting bed with dark landscape plastic (hold it in place rocks or bricks) and leave it on over the winter. Sun hitting the plastic it will raise the soil temperature beneath to destroy weed seeds.

8. Grow a no-till garden.

Every fall and again every spring, home gardeners can be found turning their garden soil to helps break up heavy clay, distribute organic matter, and deliver oxygen to the soil. Tilling in this way, however, also brings dormant weed seeds to the surface where they quickly sprout. An alternative to the turning the soil several times annually—and reduce weed growth—is a no-till garden.

You will till, but only once—when you start the garden to loosen the soil. Then, you’ll cover the soil with four to six inches of organic mulch (dried leaves, grass clippings, or hardwood chips). The mulch helps keep the soil beneath moist and also prevents weed seeds from sprouting by keeping light from reaching the surface. When you want to plant seeds or transplant seedlings, just push the mulch aside in that spot.

For a vegetable garden, this might mean creating long V-shaped rows in the mulch with bare soil only visible inside the “V.” Crops grow in the narrow rows, and after harvest, remove the spent plants and cover the area again with mulch. Once you’ve established a no-till garden, add a few inches of mulch every year (the old mulch will biodegrade and settle) and push the soil aside as described each time you plant.
