This was the first year that we tried to grow potatoes. They are white potatoes, not sure if they are russets. Anyway, they did not get very big at all, though we got a lot of them. As I'm washing and cutting them, I'm finding that about 2/3 of them have brown or black rot spots in the dead center of the potato. What causes this?
We used a neighbor's horse manure as fertilizer but it had sat for a year before we used it so I thought it should be properly composted and okay to use.
We live in northern Oregon where there is a lot of rainfall but planted in late spring/early summer so they didn't really get waterlogged. They had good sun exposure.
Not sure what went wrong. Why so small, and why the rot spots?
Anyone?

That's interesting because we had an unusually unseasonably warm May, during which we planted everything, and then a cold spell came along in June and lasted about three weeks and it was VERY cold, even got to freezing a couple of nights. All our plants suffered and most of them failed altogether. I'll bet this is what happened to our potatoes.
Thanks.
