I have a very old lemon tree that fruits well but this year half the fruit (which is still green) looks woody on the outside but when I cut into it it looks the same as the healthy fruit. The photo shows both a normal lemon at the back and the 2 abnormal ones at the front. What is this problem and how do I get it and prevent the good fruit from becoming infected?

The damage on the lemon has been caused by broad mites. The young mites move from the young foliage onto the very small fruit in October or November. They can be controlled with Yates Nature's Way Vegie & Herb Spray Concentrate. It is bio degradable and non-residual and there is no withholding period. Spray in the cool of the morning or the evening and do not spray if the temperatures are over 30 C.
