Hi Expert, I have planted dwarf navel orange during early spring which flowered and was a healthy plant until two weeks ago. Leaves are turning yellow, brown and curly. Please can you advise if this is iron deficiency or some sort of infection. Specifically it started at most bottom leaf.

Yellowing like this is usually associated with a nitrogen deficiency rather than Iron. Citrus are gross feeders so remember to give them a feed every three months with some Yates Dynamic Lifter Soil Improver and Fertiliser and support this in the growing season with some Thive Flower and Fruit Soluble fertiliser.
