Amanda, properly suited up, ready to spray herbicide on the recently germinated weeds of China Valley
We can get away with hand weeding in many parts of the Asian Collection, but China Valley is a new garden and still has a good/bad? seedbank of weeds. Pre-emergent herbicides helps, mulch helps, but we occasionally have to spray. We use Glyphosate at a low rate ~3oz 41%/Gallon of water. We don't broadcast, we hit individual plants. The good news is that every year there are fewer weeks and eventually they'll be controllable without chemicals.
