One of my favorite veggies although I mostly buy them in the store instead of growing my own. I would have never realized that they needed compacted soil. Just the opposite of the advice usually given for ones veggie growing.
Baltimore County, MD (Zone 7a) A bit of this and a bit of that
It is the opposite of most veggies, very counter-intuitive. The plants were productive on my sandy soil, but never formed good, tight sprouts until I did some research and found out about this.
