I've been growing raspberries in raised beds successfully for about 5 years now. They're 4 x 16 foot beds and yielded gallons of raspberries. This year, not so good. The east half of both of my raised bed, the plants are just not growing very well. I even had several plants - mostly just in that half of the beds - that died over winter. I transplanted a dozen plants from another bed to fill the holes, didn't find anything unusual when I dug holes for the new plants. (I thought maybe the chipmunks that are eating my strawberries had tunneled into the rasp patch, but I find no evidence.) Any ideas or suggestions?
