My own experience of sowing broad beans with holes in them is that they do germinate but only at 50% the rate of undamaged beans and crop less well also. The statement by Realseeds that holey beans germinate as well as undamaged beans I view with some scepticism. But if you do the mathematics and have pure beans germinating at 95% and holey beans at 50% with a 75%:25% split, you will still achieve th 80% minimum germination rate required by law. For those not inextricably devoted to the variety Wizard or who believe it fair to describe Realseeds' offering as poor quality and/or do not wish to spend at least 9.95 there, there is an ever cheaper Field bean alternative : 150g, perhaps 97 seeds for 2.10 with free postage at eBay.
My experience is different in that I have sowed mainly holey beans this year and they have all come up. One of my plot neighbour had seeds off me a few years ago and sows saved ones (holes or not) year on year. He gets pretty much full germination regardless and I have replicated his results after he encouraged me to keep my holey seeds.
Maybe it is different for normal broad beans. I have never tried it with them, so can’t comment. If you have never grown Wizard beans, I guess the same is true
I have other broad beans to sow this spring, so I would not say I was inextricably devoted to only growing a single type. I am a regular Real Seed customer, but that does mean I can vouch for their excellent customer service. I have faith our forum readers are perfectly fine with reading a catalogue description of what is on offer and make their own minds up whether to buy there or elsewhere.
Try Wizard beans from Realseeds or eBay bought next year when seed more readily available which gives more consistent results in the north.
You recommended them remember. I just offered a source and a link to a thread where they were being discussed, in case the op had no idea what they were.
