I planted a patch of potatoes mid spring. My girls took a bad of rotten
potatoes that had started to grow, cut them up, and buried them. The plants
grew like crazy, hit about 3 feet tall. Now, they are starting to die for no
reason that I can see. Is this normal? I thought they would grow until frost
killed them. There are no diseases I'm aware, no obvious insect damage. Plus
I can actually see the tops of several potatoes on the surface, is that also
normal? Never grown potatoes before, did not know what to expect.
