corn gluten for creeping charlie
Hello -- We live in St. Paul, and creeping charlie flourishes in our lawn and garden beds (veggie/perennials/shrubs). For years I've treated with corn gluten in Spring and Fall, but think my timing has been off for maximum effect to eradicate or at least weaken the creeping charlie. Can you clarify -- is creeping charlie a BROADLEAF weed? (Corn gluten should be effective, right?) Also -- Can you please guide on best TIMING to apply to weaken creeping charlie? (i.e. wait til it flowers, or just when I start seeing it leaf out, like now!). If it will, in fact, will not help kill the creeping charlie, when should I put it down for general health benefits to the lawn and garden, as I don't care to use chemicals? Finally -- what RATE should apply the corn gluten for max effect? PS- if I am tempted to use small amount of CHEMICAL on just the charlie, sounds like it's best to use broadleaf herbicide that contains the chemical triclopyr or dicamba. Your thoughts? Of course, I pull it out and snuff it out w/ cardboard technique when and where I can, but it's so intermingled throughout all the yard, it's tough. THANKS SO MUCH!
