i just reposted this in the soil forum.. i'm not sure how to delete it.. sorry

weeds go dormant.. just like trees do.. herbicide will not work with peak efficiency if the plant is declining into dormancy ... so it need be done sooner rather than later in fall ... make sense??? read all instructions on roundup ... mix the appropriate solution ... use a cheap paint roller [dollar store] or sponge paint brush ... and avoid spray drift entirely ... and hitting unintended victims ... ken

Hi Mike and everyone, Been away awhile, but badly needed a Citrus Forum "fix" during this historic winter! When I checked in, the first post I saw was a "name this pest" sort of question, and I said "That's CLM!" Lol, when I first came to this forum, I didn't know what a kumquat was...or a perched water table. This is a great place.... The rosemary oil is great! I have a key lime that the spider mites just won't give up the ship though. Even so, their occasional attempts to re-appear are feeble at best :-). I love the rosemary oil aroma, and I'm not concerned about spraying it in the house during winter if that became necessary. If you remember, I tried never putting my trees outside and it's been working for me, so far. SO....More snow on the way! I always said what "sold" me on citrus was seeing a ripe kishu mandarin hanging on my own tree, in my own window with snowdrifts in the background. Wow, I was sold! And sounds like I'll be re-creating that image with a key lime on Monday... Regards, Mary

Underbrush: Cut it down to the base, drill anything with a stump with a few holes about an inch deep. Fill with Rosie's greenlight killer as directed, cover with some tin foil so the wildlife doesn't drink from the stump. Sometimes the tree of heaven takes a few go-arounds. You can do more drilling and filling in a month or so, or even the end of august to be sure it's gone. The mimosa is pretty easy to take care of. Pull what you can if you can do it without damaging the ties or the vegetation you want to keep. The key is to use as little weed killer as possible to get the job done. No use in overdoing it, it really just wastes your $$$. I like Fertilome's total kill too as a vegetation killer only when necessary. I use these on kudzu, some kind of weedy cherry, hackberry (I think that's what it is), wisteria, tree of heaven, privit and mulberry stumps and they do quite well with very little product needed.
