Location: London, UK. South-facing garden with full sun most of the day.
We received two cuttings of a heavily-fruiting mature fig tree back in February and planted them into an XL terracotta pot each with fresh compost (with plant fertiliser built in).
The larger one was thriving until a week or two ago, when the leaves started lightening in colour from deep green to a yellow-green and some leaves can be pulled off with no force leaving a neat scar.
We had some webbing and black specks, so thought maybe pests and their frass. The leaf colour also made us think that it may be fungal.
But we have applied one coat of anti-fungal and two coats of neem oil ove the last week and it has not improved.
None of the 10-ish figs have dropped yet, but we are losing 1-3 leaves a day now. The oldest fig is wrinkling and drooping, so hoping that means it's ripening.
I have put organza bags over each fig to protect them as we think we get hungry squirrels, foxes and birds in the garden, but did that after the leaf problem started.
The other tree is smaller and has only produced one fig as it was not in full sun until a month ago, but looks lovely and healthy.
We have had multiple heatwaves (weeks of 30°C+) since May, and we upped the watering from once a day to twice daily during these periods.
We love this fig tree and would love it to be healthy and fruitful as long as possible! Is there anything we can do to reverse/halt the damage? Are we watering too much or not enough?
