Will my potatoes be OK to eat?

Smithrj

Hi all, last year I planted some King Edward seed potatoes but when I harvested them they all had a brown ring rot, so had to discard them all. I now have some new plants that have spontaneously appeared, presumably from some of the previous tubers that I missed and didn't dig up. My question is should I leave them to mature and harvest, and if so will the tubers be OK to eat (assuming they don't get ring rot as well)? Thanks.

Hello @Smithrj,

Thank you for sharing your concern about ring rot on your potatoes.

Ring rot is a bacteria that infects potatoes and if planted near other tubers can cause the healthy ones to be infected with the same bacteria. To prevent further contamination of healthy tubers isolation and destruction of the infected potatoes are advised. Thorough cleaning and disinfection of garden tools and containers used are recommended to prevent further spread.

Contamination can even occur with discarding the peeled skin from an infected tomato and mixed in with your garden compost. To err on the side caution consumption of the infected potatoes is not advised. I suggest removing the leftover tubers before they mature.  

Let me call on our experienced gardening members @CathM, @Noelle, and @Adam_W for further advice.
