We have been in a house with a fig tree for 3 years and each year we have had a problem that seems to be getting worse.
The small figs grown the one year suddenly start to go dark and develop a powdery mould. This affects first siongle and then multiple fruits and eventuall spreads (quickly) along entire branches, killing the branch itself.
We have just started cutting out entire branches to burn and trim back areas of weaker infection. Last year I sprayed with an anti fungal spray but this did not appear to help.
Can anybody suggest a way forward or is this simply something that happens? Should we really hack the branches back each year?
Any help would be welcome. Many thanks
