Copied from bonnieplants.com
Oh lord, I have to DEFEND myself from Karen again. ๐ฅด
Wrong, I copied some of it from University of New Hampshire Extension ( https:/extension.unh.edu)
Maybe they copied it from bonnieplants. (I see you googled it too)
I checked to see what they suggested and they worded it better than I could so I used "a couple of their lines"...SHAME on me, Pam. ๐ช
My point was that asparagus has to be planted deep.That is the basic mistake most people make.
And yes, it spreads out year after year.
Asparagus is a perennial, so put it in an out of the way place in your garden.
I have planted lots of asparagus over the years with success, how much asparagus have you ever planted, Karen. ๐คจ
