What variety did you plant ? I am in south eastern NC 8a and I’m going to give it a whirl.

Wait until the ferns are fully brown and dormant to maximize the next year's harvest. https://www.gardeningknowhow.com › edible › vegetables › asparagus › cutting-asparagus-foliage-back-in-autumn.htm Tips On Cutting Back Asparagus Plants - Gardening Know How Once you have cut the asparagus back, add several inches (10 cm.) of mulch to your asparagus bed. This will help to smother the weeds in the bed and will help fertilize the bed for next year. Compost or well-rotted manure makes an excellent mulch for asparagus in autumn....

How do I start asparagus from seed in the fall? Do I sow directly into the ground or start indoors? Zone 7b Thank you!

It suggests to plant Nov Dec. Start them in pots or trays. They are very fine little seedlings and need close attention with watering. Some sun, some shade during the day until they are a few inches high.

One 6b - Bought crowns in late spring and they were misplaced.until now August. They are not dried out and I'd like to salvage whatever is possible. If I plant them now ANDif they grow, the season will be over and cold by October. Should I refrigerate the crowns and maybe wait til spring to plant or go ahead and put them out now? Also, would it be of benefit to use innoculant to stimulate them, individually pot them indoors under grow lights and gently transplant to an outside bed in spring? What makes sense?

No planting time for asparagus in your climate zone. Maybe wrong climate.

I am learning to grow asparagus in Zone 9b. Plants are 2+ yrs old and starting to produce healthy spears. Would like suggestions on how best to grow them.

When you buy crowns does only one shoot grow from one crown? It looks like from pictures that there is more shoots coming up if your planting them 8 to 12 inches apart? Since we live in central coastal California is it best to go to a nursery in town for buying the two year old crowns?

The crown will produce many spears. As it grows it produces more and more over the years. Plant 2' apart. Buy 1 or 2 year crowns.
