How to Winterize Asparagus Plants Cut back the stalks and foliage to ground level in fall, after the leaves begin to yellow and die back naturally. Stop watering the asparagus after you cut back the stems. Spread 2 inches of mulch over the bed after you cut back the old stalks.
How do you take care of asparagus ferns in the winter?
Overwintering. If your outdoor temps dip below 55 degrees Fahrenheit, bring your asparagus ferns inside (if they’re not already there). Keep them in bright light, away from drafts and radiators. Do not overwater, this can cause root problems.
What should I do with my asparagus plants for winter?
Once the fronds have been cut back, cease watering the asparagus entirely. The idea when winterizing asparagus beds is to protect the crowns from cold injury. Spread 4-6 inches (10-15 cm.) of mulch such as straw, wood chips, or other organic materials over the crowns.
Should you cover asparagus in the winter?
For asparagus, it’s ideal to cover the beds with about four to six inches of mulch over the crowns. Prepping asparagus beds for winter will protect the roots from the cold and encourage the plants to go dormant, allowing the plant to rest before its next growth phase in the spring.
Should you cut down asparagus ferns in the fall?
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.
Will asparagus fern come back after freeze?
Asparagus fern growing outdoors can withstand some very light frost, but freezing temperatures, below 32 degrees Fahrenheit, often kill the plant to the ground. After a light frost, the plants do grow back from the roots.
Do asparagus ferns go dormant?
Asparagus ferns don’t go fully dormant in winter, but they do benefit from a rest period during which they require less water and no fertilizer. Prune the fern by removing dead stems and branches.
What do you do with asparagus ferns?
To keep your asparagus plants healthy, cut the ferny growth down only after it turns brown and dies back in the fall. Use a sharp knife and cut close to the ground. In cold climates, let it stand all winter and cut it down in the spring. The growth will help regulate soil temperatures.
When should I burn my asparagus?

Are pine needles good mulch for 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?
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.
Are coffee grounds good for asparagus?
Asparagus prefers a soil pH between 6.5 and 7, which is mildly acidic. Coffee grounds can run 5 or less on the pH scale by themselves. The grounds also add some nitrogen, which is a regular nutrition need of asparagus.
Can you cut ferns back for winter?
If your outdoor ferns die back completely in the winter, that usually means cutting them back to the ground before winter will be fine, and you can cut the fronds once they have died back.
Can asparagus ferns be cut back?
All asparagus fern types need hard pruning every three years to rejuvenate their growth. It is best done in spring before new growth emerges. Cut back the entire plant to within 2 to 3 inches of the soil using sharp, clean pruning shears and discard the fronds.
How do you cut back asparagus in the fall?
Pruning Tips Wait until all the foliage has died back and turned brown or yellow. Cut the plants back to the soil surface and apply mulch to help against deep freeze or changes in soil temperatures. If you have issues with disease or insects, it’s best to cut the tops off of your asparagus.
Do I need to protect asparagus from frost?
Frost can kill young asparagus spears when they first emerge from the soil. They will shrivel and turn black, making them inedible. Cut off all damaged spears. An eight-inch layer of organic compost or other mulch will help to keep the soil warmer and protect the crown from very cold weather.
Do asparagus ferns survive winter?
Asparagus ferns prefer warm and humid climates (about 70 degrees F) and cannot withstand temperatures below 55 degrees F for very long periods of time. Asparagus ferns do not require periods of winter dormancy but will appreciate a resting period and reduced watering during the winter months.
Do asparagus ferns come back every year?
