Wellllllll I may not need that roundup. we'll see. My lawnmower broke right before I went to California, and I had not mowed for at least 2 weeks because it had been so hot and dry. Of course it rained and cooled off while I was gone. My husband got home, fixed the mower, and it looks like he mowed that hilllside. The weedy grasses that popped up in there hid the roses, so I can't blame him.
Maybe a severe pruning will encourage the Sea Foams to bloom? It's so late in the year, I kind of doubt it.
Steve, how do you handle weeds growing at the edge of the seasonal stream? Our pond is really low right now, as it usually is this time of year, and we have weeds 4' tall. I can't mow them because the ground is too soft. Once the rains come, they'll be under 2 feet of water, but for the 3 months or so that we're fairly dry, it's ugly. Do you have to walk the banks with a gas trimmer? Or spray chemicals? Or do you plant roses thickly enough that they keep the weeds down? Here, at least, roses don't grow dense enough to serve that purpose.
So far, i don't have cattails or loosestrife, but I am looking out for them in amongst the ragweed, knotweed, and pickerel.
