I seem to have trouble with butternut squash Hunter. Last year i only got a couple of fruit and I persumed it was because they had a shock when planted out. So this year I carefully hardened them off and I planted a lot - I have a new allotment and I reckoned their big leaves would smother weeds. I planted some in the old veg garden under sweet corn. Lots of leaves but I cannot see any fruit. On the allotment a good proportion of the plot has gone under leaves and stem but i cannot find any fruit. My single pumpkin nearby is fruiting well and the courgettes are doing what courgettes do best, producing more fruit than you can possibly cope with. I planted them on top of a little mound of well rotted manure. Should I give them less manure?
