Hubby has some wild asparagus that he watches grow, but I don’t know a lot about it. I know that they need good drainage, and if the ph is below 6 it’s bad news. They also need phosphorus, and 10-20-10 fertilizer is what is advised prior to planting the crowns the 1st year.
Each crown will produce approximately 1/2 lb spears. Male hybrids outproduce female plants, since females expend energy producing seeds in addition to spears. Space wide between plants to help prevent fungal diseases. Watch out for beetles.
Do not cut down fern growth after last harvest till Spring.
That’s about all I have in the info I printed for Hubby.
I'll just stick with side-dressing and cultivating, and let them do their thing.

Out of curiosity- why should I not cut down the asparagus fern growth til the next season? Does that apply where we have cold (can be sub-zero here at times in winter) ?
