hardly ever get figs. cut fig tree back the other year so lost one years fruits. Had 4 figs in the summer but theres loads coming through maybe upto 50 various sizes, a couple of the leaves are turning orange but the bush/tree is quite big green and leafy. I have a thick transparent tarp If I tried to cover the fig with this could I keep the fig warm enough to allow the figs to finish growing? Or is there something else I can do. It is planted and large, I live in south east cornwall??
