I am looking for help with an issue that I have with my rhododendron and camellia garden. When I first planted the garden 25 years ago I placed landscaping fabric down and then covered it with bark mulch. Over the years the bark has decomposed along with the leaves and the needles from the neighbouring cedar and birch trees. Unfortunately this has created more than an inch of extremely compacted “soil” on top of the fabric. The soil is so hard that water will just roll off it. I attempted to remove the soil and fabric in hopes of exposed the soil underneath. As you can see in the photo I was also removing a substantial amount of the roots. I assume if I were to continue to remove the landscaping fabric and the soil above it I will damage or kill the plants. My first thought was to add another layer of mulch but the hard soil underneath would still provide a barrier for the water. The other issue I have with mulch is that it will be a great place for weevils to live. During the early years of the garden weevils were a big problem. My second thought was to use my manual lawn coring aerator (please see photo) to create holes through the hard soil and then add a layer of mulch. Would you have any advice or suggestions on how I can solve this issue? Thank you so much for your help. Take care Michael New Westminster.
