|Have a magnolia tree planted in back yard. Cannot get anything to grow underneath it, dispite planting shade loving plants like hosta or spiderwort and using drip irrigation in case tree is hogging the rain. Even tried a dwarf hemlock. Everything has died. Rest of garden is beautiful. Magnolia is trimmed up about 6-ft from ground showing lovely double trunk, but ground is bare underneath. I know I've had trouble under some black walnuts due to their toxicity, but have never heard of a problem with Magnolia. Am currently using large containers under, but would love to be able to plant directly in soil. Any ideas or suggestions?
