Organic Weed Killer

Asked May 13, 2017, 10:46 AM EDT

Hello - do you have recommendations on organic weed killers I can use in a vegetable garden/blueberry patch? I read about vinegar/dawn/epson salts but don't think it isn't truly organic. Thanks,

Home remedies and products such as household vinegar are not recommended as it kills the top growth only. A horticultural grade of vinegar is caustic and not recommended. Epsom salts is not an effective weed control. In general, these products can affect the soil and the growth of your plants.

Take a look at our vegetable website for organic ways to control weeds http://extension.umd.edu/growit/food-gardening-101/step-5-taking-care-your-garden#weeds

Blueberries - Remove weeds by hand and mulch to conserve moisture and prevent weeds. Pine bark mulch, rotted sawdust, and compost are good mulches. Apply them to a depth of 2 - 3 inches and replenish whenever necessary. Avoid mulch with high pH, such as mushroom compost.
