When should I burn my asparagus?
As soon as the field is passable in early spring, mow or chop the old asparagus ferns with a brush hog mower or flail chopper if not chopped in the previous fall.

When can I cut back asparagus fronds?
The asparagus foliage can be cut back to the ground after it has been destroyed by cold temperatures in fall. However, it is generally recommended that the dead foliage be allowed to stand over winter. The dead debris will catch and hold snow. Snow cover helps protect the asparagus crowns from freeze damage.
What to do with asparagus at the end of the growing season?
Leave asparagus stems on plants as long as they remain green—well into autumn. When stalks turn brown and brittle cut them off at ground level and top dress the bed with compost or manure. (Place cut stalks and ferns in the trash—not in the compost pile; asparagus-beetle eggs can overwinter in cut stalks.).
How do you winterize asparagus?

Should I rototill my asparagus?
Early spring is also an excellent time to fertilize the asparagus planting. Apply 50 pounds of barnyard manure per 100 square feet. Lightly till the manure into the top 2 or 3 inches of soil with a rototiller or spade. This must be done in early spring before the asparagus starts to grow.
Why do you cut asparagus below the ground?
cut. It’s important to note there are no benefits or advantages of cutting asparagus below the soil with a knife.

Should I put mulch on my asparagus?
Yes. Mulch should be loose enough for water percolation. Straw, pine needles, pine shavings or bark mulch work well as mulch choices. Avoid using dyed mulches (black or red).
What happens if you don’t cut asparagus?

Should I let my asparagus go to seed?
Ferning out in asparagus is actually a good thing, as it indicates that photosynthesis is being promoted, therefore, nutrition production and absorption increases. As the asparagus ferns out, female spears produce green berries that eventually turn red. These berries/seeds, however, are unlikely to produce new plants.
Do you trim asparagus the first year?
Before Harvesting Do not harvest the spears in the first or second year (the plant needs time to grow out its root system), but cut down dead foliage in late fall and side-dress with compost. During the second year, side-dress with compost in spring and early fall and cut down dead ferns in late fall.
