I have tried the three sisters this year for the first time as I am entered into the "Best plot in Liverpool competition".One of the criteria for points is for different ways of growing things and so I have huge pots containing, runner beans, Alderman tall peas and a courgette. I also have runner beans in grow bags.I will report on the success or otherwise on my site in due course.http://www.allaboutliverpool.com/allaboutallotments1_homepage.html
With some, esp tender ones it is easier to control the environment... it warms up faster than the soil. Also some like carrots can be easier to grow in compost. :-\
