prevent weed seeds

Apply vinegar with a spray bottle, pump sprayer, or brush. Like other natural herbicides, vinegar cannot differentiate between weeds and other plants. Do this early in the morning, when there’s little wind, to avoid contaminating nearby plants. Vinegar’s killing properties are activated by the sun, so try this on a cloudless day, which also ensures that rain won’t wash it off before it works its magic.

Cover your planting areas with mulch and you’ll keep weed seeds from coming into contact with the soil in the first place. Mulch will also keep sunlight from reaching seeds that are already underground, so they won’t get a chance to sprout. Mulch offers the added benefits of retaining moisture and breaking down to enrich your soil. And it looks really pretty, too.

Did you know that corn gluten meal is birth control for seeds? Sprinkle it on your garden and it will keep weed seeds from germinating and growing into plants. Of course, corn gluten meal will keep any seed from germinating, so don’t try this on your vegetable garden until your plants are established and you’ve finished planting seeds.

You can rid yourself of weeds the old fashioned way—pulling them by hand—if you’re vigilant. Wear a dedicated pair of gardening gloves for the task to avoid inadvertently transferring seeds elsewhere. Good gardening tools like a claw or sharp trowel can help you loosen the weed roots from the soil first. Pulling a weed completely out by the root is the only way to ensure it will not return.

Smother weeds and prevent new ones from growing by covering them with old newspapers. A thick layer of newspaper will keep sunlight from reaching weed seeds, so they can’t sprout. Wet the soil first, and then lay your newspaper down, wetting it thoroughly again before covering with mulch. This is a great way to recycle, and as a bonus, you’ll encourage earth worms to come and stay.

Scald those pesky weeds with boiling water. Just grab your kettle off the stove and bring it to the garden. Pour a stream of water carefully on the crown of each unwanted plant. Tough perennial weeds with long tap roots may take two or three applications, but will eventually stop coming back. Use your hot pads, of course, and definitely take the precaution of wearing long pants and close-toed shoes.

Cover crops differ from ‘regular’ crops in that they are grown solely so the soil is covered, rather than for harvestable things. Cover crops are used by lots of folks – grain farmers, vegetable farmers, flower farmers, and they offer lots of soil benefits, as described in this blog. But they can also help control weeds! Let’s explore how.

Pretend you, the weed seed, didn’t get eaten. It’s time to think about germinating. But you, the weed seed, can only germinate if you get the right ‘cues’. Weed seeds are incredibly smart. A lot of weed seeds will only germinate when they sense ‘pure light’. Light changes as it passes through green leaves. Weeds don’t want competition, so they will wait until there are no other living plants around before they germinate. So, what if you planted a cover crop? The cover crop, alive or dead, is blocking that pure light from hitting the soil, where you and your weed seed friends live. You might never get the cue to germinate.
