Disapointing oca harverst (and replanting)

Swedboy

Have been waiting for the frost to hit my ocas (in Bristol) but decided to dig them up today. The harvest was appalling. Only two fully formed tubers. Sadly all of them have been nibbled by slugs or somethings. The ones that had fared best was the ones that had developed on the stems of the plant. They look like the tubers and are like big marbles. Are those edible/can be used as seeds for next year?

The other tubers that has been damaged, can I cut off the damaged bits and plant them or will that cause them to rot.

This is so disappointing as the plants looked really healthy.

I bought 3 roots of these early last year and planted them in the polytunnel.  We started harvesting just after Xmas and the crop has been good with not too much damage.

However, the flavour has been disappointing and I'm not keen on the texture either.  We've had them roasted with a  little butter and s&p mostly.  Their lemony flavour improves if you harvest them, clean them and let them sit for a few days but TBH they are desperately dull and boring and there is a very fine cooking line between having them slightly crunchy and utterly mushy.

I won't be giving them garden space again.

I quite like them raw and in stir-frys. They fascinate me and that's why I'm growing them. First year I got a decent return but this year (second) was horrible. Not sure if it was because they never got hit by frost. My understanding is that they need to be hit by frost to bulk up.

I'm growing them in pots so they don't take to much space.

No frost in our PT and hardly any in the garden as a whole this year.

I live in Bristol by The Prison so perhaps its just the soil in our area.
