I've made some mistakes in my gardening life but two that I'll never, ever repeat are to grow bush tomatoes and Oca in my polytunnel. Four tomato plants have virtually taken over a bed about ten feet by five feet and that end of the tunnel is a maze of canes and string with the plants now at ten feet high.
As for the Oca, I've no idea as to what harvest I might eventually get but the foliage is on a total invasion of space and has covered the paths so I can't help but walk on the stuff.
Next year, if I keep them (and that depends on how tasty they are), the oca will be grown outside and it's back to plain old cordon varieties of tomatoes like Shirley and Alicante grown like the nurseries do with two plants to a gro-bag. To hell with the so-called heritage bush varieties
