This native planting was installed by another landscaper, but bindweed took over the space shortly after installation. I went in and removed the bindweed, and later came back and removed the bindweed again, but added a thick layer of recycled cardboard and a heavier layer of mulch to slow down the growth of the bindweed in between maintenance visits. My customer is dedicated to not using chemicals, and I am happy to help work through this process without them!
