Yeah my Dad has been growing for years and he says there's live plant between buried tuber and surface that'll regrow. Yield might be less and slightly later though. Fingers crossed.
My next project is some similar covers. Ta for the inspiration.
Similar story at ours, I made such a commotion when i spotted them one of the older guys came over, he said they would sulk for a few weeks and be fine.
Some of them will recover ok I reckon. Kicking myself for not using a spare mesh tunnel cloche I have stashed at the allotment.
Fruit cage on point! I picked up two more pallets today so can go about making some more of my brassica covers.
