How long do YOU wait before you cut back tulip foliage??
I have read to wait til foliage starts to die back and then I have read to wait a certain amount of weeks and then you would be safe to cut them back. How long do you wait? They emerged in Feb and I was hoping by the end of April or mid May would be enough time for them to build up enough energy for next years bloom. Let me know what you do. Thanks, Judy
