We tried some balcony potatoes in a thing from HD, didn’t go terribly was just a lot of extra work compared to the other veggies. Need soil to top up the crown.
You just gave me an idea for peas. I’m kinda saying eff my arm right I gotta get my garden ready. I do have a steroid shot, it’s just 2 months out unless a cancellation happens (obvs others are on list first too) so I’m expanding with 6x 4x2 metal beds. Doing it out of lumber was damn near the same price in the end WTF. I have two feet between them and dead space against the fence. I can maybe put a trellis on the fence with pea pots on the ground!
