SWEETCORN - does it need deep soil?

[Sanjo]

Thanks Bazzaboy. I do have spuds in 8 old compost bags black side out. I was worried that it might make OH's shrub border look a mess (not that he commented and has been very supportive) but once they came through they blend in. It's just that I wanted to try something else. Anyway today my dearly beloved has actually dug over that lawned area and we have started to fill it with soil and compost. Instant garden. Thanks all for the advice. I will report back on the success (or not!!~)of the mini corn in this type of bed as it may help somebody else. Sanjo
