When is the best time to cut down asparagus ferns, after we harvest asparagus, or in the fall?
The fronds produced by asparagus are essential for maintaining healthy, vigorous plants. Allow them to remain intact until they die back naturally in the fall. I usually wait until my garden has experienced one or two killing frosts. Discard or compost the dead fronds to prevent diseases and insect pests from carrying over into the spring.
