Yes, it remains quite a puzzle to my mind. As you say, the plants have had plenty of heat which I imagine is why it is so ultra vigorous, and the day length is longer but not so much longer than in northern Spain. Ah well, I guess we’ll just have to accept defeat!That is interesting, I didn't realize the Mongeta bean was grown in northern Spain. Wow, so southern origin can't be the reason then. I wonder what causes such a prolonged growth period before pod formation then? With a polytunnel they'd likely get more than enough heat units. I had the exact same experience with the Floreta bean as I did with Mongeta too.
