Potatoes falling over
The potatoes in my potato bag were growing and looking green and healthy. Now suddenly they're falling over and dying. The largest had some yellowing leaves at the bottom. I attributed that to overwatering. But then the stalks of another plant (which wasn't yellowing) just fell over and the plant started to die. It looks pinched and dried right at the soil line. They're several inches high. Way too big for damping off, aren't they?
The plants in the raised bed are doing fine. They're younger than the potatoes in the potato bed, and the heat makes them droop, but they're fine otherwise. One's even starting to bloom.
I know it's not soon enough for the potatoes to die off in preparation for harvest. What gives with the spuds?
