Embrace your “weeds.” Many plants that we think of as “weeds” are beneficial to the biodiversity of our yards. Some weeds are actually edible, and can be a great (free!) addition to your diet![8] Even if you choose not to eat your weeds, plenty of insects may choose to snack on your weeds instead of your garden!
Some weeds can actually deter pests from entering an area as well.[9]
You can certainly “pick and choose” which weeds you allow to stay on your property; you can decide, for example, to get rid of poison ivy, but keep dandelions or thistle. Encouraging biodiversity does not insist on allowing every plant or animal species free range of your land.
