Weeding is one of the most time-consuming parts of gardening—but what if your plants could do the job for you? Some vegetables naturally grow with dense foliage, sprawling habits, or fast ground coverage, making them excellent at shading out weeds before they take hold.
These weed-fighting crops don’t just reduce maintenance—they also help conserve soil moisture, prevent erosion, and create a healthier growing environment for your garden. With smart planning, you can build a veggie patch that’s both productive and low-maintenance.
In this article, we’ll highlight 16 vegetables that choke out weeds naturally, so you can spend less time pulling and more time harvesting.
