Ferns from Asparagus growing outside the raised bed

Asked May 6, 2017, 7:26 AM EDT

This is the second year with a 4x8 foot raised bed of asparagus. The asparagus drowns have already grown four foot ferns, but many baby ferns (1-2 inches) are growing outside 1 - 8 inches outside the raised bed and moving toward a low-lying tomato and perennial flower area. Should I hoe these out to keep the roots healthier and growing within the box or should I expect a gradual movement away from the box with new crowns more adapted to a wetter spring soil? Do asparagus crowns send out crownlet? Thanks, Lisa Greenberg

Asparagus grows by seeding and expansion of the existing root crowns. They are most likely advancing by both forms of propagation to a space that is favorable to their growth, and where there is less competition from the well-established plants. You could simply hoe out the seedlings you don't want if you want to keep them retained in your raised bed and also to reduce competition with your tomatoes and perennial flowers.
