Onions for show

Hello .... new to the group and looking forward to being educated .... and perhaps helping on the odd occasion.

I have entered our local flower show (14th Aug) and, among other things, plan to show some onions. I have three types Senshyu, Radar and Centurion. The first two are going very well. The Centurion were planted later and are still developing. How far in advance of showing is the ideal time to lift  onions. I seem to recall reading that three weeks or so was about perfect. Any advice or help much appreciated. Many thanks.

Many thanks Dave. I grew Centurion because I remember reading that it was "the one for the show bench" .... but it's all really just for fun among the folks in the small village where I live". I have a small private bet going on with one of my friends on the onions .... he's probably a subscriber to this group too :-))) The Senshyu and Radar look good (I didn't know Radar was Japanese too) so I guess I'll lift them in a couple of weeks and reach for the raffia. As I said - it's only for fun. I think the entry fee is 50p and the 1st prize is £1.50 - got to keep it quiet however - there may well be tax implications ;-))

Thanks again!

Thanks Spana. I'll be sure to read the rules carefully.
