I am a slave to a slope weeding and weeding and weeding. We had planted 500 kinnickinick on a slope instead of doing basalt wall rock. Well, we are wondering now why we did such a stupid thing. Ultimately, it will look really nice with greenery on the entrie slope, but the weeds are out of control. It's going to take probably two more summers for these plants to be able to choke out weeds. We can't put mulch because of the wind here. Someone recommended rock mulch, but after reading opinions of that stuff, not sure what to do. I put down a pre-emergent (Amaze), but doesn't seem to do much. Can anyone please help? I stress out every day about the weeds instead of enjoying our custom home.
