How do I treat my lemons that have curled leaves, peeled trunk and dark skinned lemons?

My friend's lemon tree is looking very sick with its peeled trunk, curled & white spotted leaves, and dark skinned lemons. It also gave many less fruits than previous years.

Hi Thi,

The lemon tree looks very unwell, and may have scale insects on the leaves as well as the splitting bark caused by collar rot and root rot diseases. Apply some Anti Rot to the foliage and this will translocate throughout the plant. Remove any mulch that is up against the trunk to help reduce collar rot. If you see an insect pest such as scale then apply some PestOil to the leaves. During Spring and Autumn fertilise the tree with citrus food. Mites can also affect the skin of the lemon and it this is evident apply some Yates Nature's Way Vegie & Herb Spray Concentrate to the lemons when you first see the damage.
