Looking at my climbing beans, pumpkin, tromboncino and courgette just now, well for the last few days. I have come to my very new to growing conclusion that trying to get a head start on these type crops, with good daytime temperatures but still not right night ones doesn't actually achieve anything good. Putting 5l plastic bottles over them each afternoon keeps them alive, sort of in stasis. But the young plants i put in only a week ago when those night temperatures kept above 10 degrees, well they are well on the way to catching/overtaking the ones i cared for through the last weeks. It will be interesting to compare how the early started and recent plantings produce. Will the later ones actually give a better crop?
