I spent 5 minutes outside with my camera, waiting for the schoolbus this afternoon, and I found:
some weed I haven't identified yet, and lots more.
I won't even begin to list the weeds that grow in the Rose Field. It's been too hot here for the past week to get out and do any consistent work outside. Add to this, we've had really good rain for the past few weeks, and we have a formula for explosive weed growth.
Here is one of my secret weapons:
Ornamec is a selective herbicide that only kills grassy weeds, and it doesn't harm broadleaf plants (like roses). I can use it in my rose beds to kill Bermuda and Crab Grass, which are so incredibly hard to get rid of any other way. (The same chemical is available ready to use as Ortho's Grass-B-Gone.)
If you want to give Ornamec a try, be sure to read the label to make sure that it is safe around the plants near your grassy weeds. Roses are one of the plants specifically mentioned in the instructions as safe.
For broadleaf weeds in large areas (away from the roses!) I use glyphosate (expensive brand name: Round-up).
