Spot sprayed some cattails today on the two wetland ponds. I don't mind the bullrushes yet but cattails are just rude and don't know how to behave. Twice a summer I turn them yellow with a little Cattplex and surfactant in my little two gallon sprayer to keep them from trying to take over.
If you spray them in late September, that will be the most effective because they are taking nutrients down to the roots for the winter.
I've never had any make it spot spraying twice in summer, within two days they turn yellow and die to the roots. I just get very small groups of them and pound them before they even think about making heads. As shallow as my wetland ponds are new ones still try to pop up early every summer along the edges here and there.
