Why is my new lemon tree losing leaves, they are going yellow and curling up?

It is still in a pot, 12 months old. Growing at Gympie Qld. Recently put in a bigger pot.

Fruit and Citrus • Pests

Hi Julie,

Leaves yellowing could indicate a deficiency and leaves curling could indicate attack by citrus leaf miner. At this stage, your tree being in a vulnerable situation, be careful not to over-fertilise the tree. We would recommend applications of Yates Dynamic Lifter Liquid Concentrate. It's certified for use in organic gardens, and contains seaweed, blood&bone and fish meal to help developing new roots and restoring healthy growth. There is an insect called citrus leaf miner which attacks the new growth on lemon trees. The moth lays its eggs in the soft new growth causing them to curl. This pest is active during summer/autumn. When opening the curled leaf, you will see squiggly lines throughout the leaf. These are the eggs that have been laid. You can simply trim off those affected leaves. As a preventative spray during summer/autumn, you can spray your lemon tree with a product called PestOil. This product sprayed on the leaf leaves a residue and deters the moth landing on the leaf. Nurse your tree along and I am sure it will come good.
