Curled Leaves on Fig Tree

How does this happen--rusty nails or rusty fencing?

@ducks4you
Ferric Oxide toxicity happens thousands of different ways.
Planet Earth is 35% Iron.
Most of it in the Earth's core.
However, there is a lot in the soil.
That in the soil is mostly Iron(ii) Oxide which is black & not water soluble.
Some occurs as Iron(iii) Oxide or Ferric Oxide which is red.
Some as Iron (Chloride, Sulfate, Nitrate, ect)
These can under hot conditions ion exchange with Calcium Carbonate & create Ferric Oxide.
Iron Sulfide fools gold can be turned into Ferric Oxide by Fungi, E.Coli & other microbes after thunderstorms, often Ozone dissolved in water as a catalyst.
Iron Chelates often unchelate creating Ferric Oxide.
Water runoff from cement often unchelates Iron.
Many Iron Chelate products are Iron Sulfate with chelating chemicals added.
These create Ferric Oxide & chemicals & Sulfate react with Calcium Carbonate & other minerals.
Iron-EDDHA is by far the safest Iron Chelate.
Others can ion exchange with Magnesium Sulfate, forming Iron Sulfate, Iron Sulfate ion exchanges with Calcium Carbonate, Carbonic acid bubbles of leaving behind Calcium Sulfate & Ferric Oxide, as Iron ion exchanges with water molecules.
This is the condensed short list of how it happens.
Putting Citric Acid in the soil helps.
Spraying branches with (1/2) teaspoon Citric Acid per gallon helps to.

Thank you Zinhead. I never expected an answer 5 years later!

The figs don't seem to ripen. Is it because of the ferric oxide?

Put Citric Acid in the soil.
Plus (1/2) teaspoon Citric Acid per gallon of water & a pinch of Manganese Chelate approximately (1/100) teaspoon into the Citric acid solution.
Mix very well & spray branches.
Should correct the problem.

Magnesium Sulfate also slows ripening.
It might make fruits big, but it dramatically slows fig ripening.
Manganese however accelerates fig ripening!
Don't need much, just a very small pinch in Citric Acid sprayed on branches.

Can you please tell me where I can buy these products? Would they be at big box stores?

You can find Manganese (Sulfate or Chelate) at most nurseries.
If you use Manganese Sulfate, then use half as much.
citric acid is available at many nursery, grocery stores, hardware stores & online at thousands of websites.
