Corn Gluten meal is a nontoxic byproduct of corn syrup processing, so it's not a chemical, at least not a synthetic one that is, it's a foodstuff that basically releases a natural herbicide that prevents seedlings from setting roots, which in turn kills the plants. From what I understand it has a nitrogen content of 10% just because of what it is, so you don't want to put it on beds that will have plants that don't like a lot of nitrogen, like carrots. But most gardens and lawns need nitrogen, so it's nitrogen content has an added benefit of helping to fertilize as well. It is shown to be 60% effective the first year, and 90% effective after a few years. If it burned weeds then it would harm established plants, which it doesn't. The EPA has approved it for use on turfweed. Because it prevents seedlings from setting roots, it wouldn't do anything for established weeds (like your bindweed) And I got this from Organic Gardening, whom I trust. I'm not an employee of gardens alive! or anything, in fact I've not even tried it though I'm going to order some! It just so happened I had read about corn gluten meal in an article the same day that someone here posted about it....go figure, because a few days before I had called Organic Gardening to get information on Round Up and alternatives to it, so I have about three articles they sent me two of which mention the gorn gluten meal. I hadn't heard of it until right then either. Oh they also have a guide for identifying common weeds, controlling them through natural means, why they show up in your garden (they can indicate things about your soil) and why you just might want to KEEP them in your garden. An example: A mulch of dried Quackgrass kills slugs. Dandelion greens are good in salads, Clover fixes nitrogen into nitrogen deprived soil (in fact it is attracted to nitrogen-poor soil and is often used by gardeners and farmers as a cover crop), and encourages honeybees to visit. Unfortunately they had nothing positive to say about bindweed :/.... and their advice for getting rid of it was to keep up with pulling it out. You can order it on-line from http://www.gardens-alive.com/ and it is now called WOW! Plus. "WOW! Plus lets you control crab-grass, dandelions and other pesky weeds while feeding your lawn with a complete, balanced, all-natural fertilizer! It’s easy to apply and saves you time and effort. You can now weed and feed your lawn organically with just one application! "A by-product of corn syrup production, our pre-emergence weed control eliminates germinating weeds. It helps you achieve a beautiful lawn your neighbors will envy. And there’s no need to post "Keep Off - Herbicide Warning" signs, because kids and pets can play on the lawn right after application! .... "How WOW! Plus works "Soon after sprouting, young weeds send out secondary "feeder" roots, which are especially adept at drawing nutrients from the soil. But WOW! Plus stops these feeder roots from developing. Without them, seedlings quickly die - usually before you notice any green top growth! Dandelions, crab-grass, creeping bentgrass, foxtail, lamb’s-quarters, purslane, redroot pigweed and many others can’t survive their first few days, and can’t make your lawn an eyesore. "Don’t worry about over-applying WOW! Plus. You can use eight times the recommended rate without harming your grass, and you’ll find that high doses are even more effective in controlling weeds. [though I wouldn't add any nitrogen fertilizer if you used that much on your lawn or your garden] "And don’t worry about lingering synthetic chemicals! There aren’t any! Unlike traditional chemical treatments, WOW! Plus lets your family, friends and pets enjoy your lawn immediately after application. " They have something called "Scythe Weed Killer" which might work on your bindweed, Pam, though I'm not positive. I might want to use it on the blackberries and thistles though I'm not sure ANYTHING will work on those :/ If you have more questions about the product you might ask your county Extension Office or call Gardens Alive!
