I know I said another 10 days, but I had another look at the top end of the plot and it looked good and moist but not wet, easy to work without clogging so, to hell with it nothing ventured, nothing gained, in they went. Warmth will not be a problem, I was down to shorts and a T shirt it was so hot. The broad beans seem to think so to, as they are all flowering merrily away. Even the bees were venturing around, the hives are only a plot away so I expect they are on short excursions at the moment, but they soon found my broad bean flowers.
