Is the curled leaves something that happened over the winter? If so, then it is possible the plant had a severe case of winter burn. The wind, cold and sun in the winter can kill the leaves on the plant if it is not protected.

If this leaf damage was there prior to winter, then it is likely fungus or pests. You should treat the plant with a fungicide and a pesticide. I personally like neem oil as it does both and is organic.
