I have an “attach & spray” weed killer but need to treat weeds in an area that doesn’t have faucets nearby. I’m thinking of using a 1-gallon pump sprayer instead of a hose. I read through the directions but couldn’t find the ratio for mixing it…

Will these weeds reduce in winter?

These weeds are about 4 feet high. I can either weed whack them now (late September), or wait until early spring. Will I have a much easier time cutting them back in spring? I'd prefer to do it now, but if it saves a lot of effort, I'll wait 6…
