You must be south of me. I'm in Bastrop. My "ferns" (not sure what to call those) are over 5 feet tall now! I'm going to let them grow now until they die out when it freezes. I got one spear the first year!

Zone 8b, Central Georgia. Since we have pretty hot, scorching summers, would it be better to plant asparagus where it doesn't get full afternoon sun? Just afraid it couldn't take the heat.

Have been away and have come home and asparagus is already up, do I cut if and start again or just harvest what comes up?
