Have garden bed in semi-shade, backed up by Pyracantha Firethorn (30-40 years old). Put down weed suppressant & slate mulch 2 years ago and now almost all of my new shade-tolerant plants are dead (except Phormium). Is the mulch preventing proper drainage and not allowing the plants to grow? The soil is heavy/clay and never gets dry. I have spent a fortune on mulch/plants and am now completely frustrated!
