How tall should you let asparagus grow?
Although an asparagus bed rewards you for years, you’ll need patience to wait on the first harvest, which doesn’t come until the second spring. The first spring that you plant, leave the plants alone to grow into tall ferns (4-5 feet high). This builds strong roots that send out the asparagus shoots the next spring.
What happens if you let asparagus keep growing?
Picking the pieces slowly stresses the plant, so when it’s left alone for the rest of the year, it’s able to regain strength and grow new roots. This in turn helps have more production in the coming years. Once the asparagus is left alone, it grows into a large shrub-like fern.

Should asparagus be cut back?
