Loosing a large tent in the back yard last year really hurt. The bed that is up close to the house has lost a very prominence piece of shading and all hell is breaking loose now. Weeds are shooting through the stones, some of the ferns are simply falling over exhausted and my poor poor Hosta is starting to turn brown!
Fortunately I think it has more to do with my watering them than anything else. After reading through some other sites on line I came across this page;
Since the browning appears to be random and spotty, I believe they are simply to moist. I put a large cement bird bath into the middle of the bed and I think filling it up with water is causing my Hosta's to stay damp.
