Hello, I have recently switched some of my older wooden raised beds to metal beds. They are deeper and will affect my perennial asparagus bed. I’m not sure if I can cover the crowns up an additional 8 to 10 inches from where they already are and have been growing for several years, or if I have to dig them all up to move them up higher in the soil. My concern is that they’re just now coming up and I don’t want to lose this year’s crop . I know some things like tomatoes can be planted several inches deeper when you are transplanting them. I was hoping with how huge asparagus plants get that they could take an extra 8 inches or so of dirt on top.
