Last fall I planted 4 raspberry plants, two Heritage and two Killarney. Recently the two Heritage have had a handful of leaves curl up and fold in half so you only see the bottom of the leaf which looks very white. Today one of the Killarney plants had a few leaves that looked similar. I attached a couple pics below.
Some background. The soil is mostly clay, but I mixed a bunch of compost into it when I planted the raspberries. We have gotten a lot of rain lately so I wondered if it could be a cause of too much water? I haven't used any herbicides or fertilizer recently.
