As this was our first time growing beans I thought we would try different methods.
So I put my canes up, and planted the one side with seeds straight into the bed, and then planted some in small tubs in the greenhouse.
Three weeks on, the ones in the greenhouse are thriving, and the ones on the allotment were nowhere to be seen.
I decided to investigate, and dug up one of the seeds to see what was happening.. and nothing.. there was nothing there.
In the end I checked around 10, and not one was there! as I was "investigating" a little old bloke walked past and said. you looking for your beans, I replied "yes they have gone" to which he repied "mine did that last year" and just carried on walking.

Whats that all about?
