We have a fig tree on the south/east side of the house. It gets full sun in the afternoon, but partial sun for the morning. The tree has been in the ground for around 10 years I am guessing. Previously the tree has had black scale and also fig leaf bug that skeletonised the leaves a few years in a row. We got rid of both these problems (somehow).. but lately the trees leaves new growth and old, is curling up and browning. I have read that it could be fungus or too much water or not enough water. I was hoping someone could tell me what it is and if it can be treated? or is it time for a new tree?
I hope one of you garden gurus can help
Cheers
