Why are the Fig trees leaves curling?

[AngryBird]

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

Hi @AngryBird,

Let me tag helpful member @Noelle for her expert advice on why your fig leaves might be curling.

There's also helpful advice you might be keen to read in this previous discussion: Any tips or advice for growing fig trees? There's also a comprehensive guide on the Bunnings website: How to plant, grow and prune fig trees.

Hope that helps.

Hi @AngryBird 

Can you please tell me where you live (suburb/city), what the soil is like and how often you water so I can glean a bit more knowledge on which to base a diagnosis?

Hi Jason,

Thank you for your reply. Appreciate the help.

Kind regards

Hi @Noelle,

I am in the Canterbury area of Sydney. The soil is Sandy and mulched lightly, I think its getting water at least once a week.. I can add some more photos if needed.. I could add a pic of the soil too if that would be useful. The fig is planted right next to a citrus tree, that grew more leaves than fruit last season.. I feel this crazy unpredictable weather is not good for the fruit trees.

Cheers

Hi again @AngryBird 

Thanks for the info re location and soil. The pics don't look to me like the tree is diseased.
Given you have a sandy soil it's my opinion the fig is not getting enough moisture if you're only watering once a week. The leaves are exhibiting symptoms of stress - curling and browning from the edges inwards is highly suggestive of lack of moisture.
If it doesn't rain, I would suggest watering at least twice or maybe even three times a week over summer, especially when temperatures are high and there's also a drying wind.
Mulching the soil with compost or similar organic matter will also assist in moisture retention and keeping the soil cooler around the roots.
