Answer: Spotted leaves might indicate a pest is present. I've had trouble with aphids on my shamrocks in the past. In fact, one infestation was so bad that I just pulled off all the leaves and blossoms, and repotted the little bulbs in fresh soil. The plants quickly regrew, and the aphids were gone. Red spider mites are also fond of shamrocks. I suggest repotting -- the plants should put on new growth immediately, and be in good shape for St. Patrick's Day! Enjoy!
