I have my first satsuma tree. It's 3 years old. Spent the first year in a pot. I transplanted it into the yard in Metairie last summer, and it is now in its second year in the yard. Most of the leaves are shriveling, but some appear healthy. No evidence I can see of pests. Can you please give me some idea of what is happening and what I can do to save this plant? I listen to you on WWL every Saturday and respect your knowledge of these things.

The healthy leaves are the old growth made back in the spring. The deformed leaves are the late summer flush of growth growing out now. The late summer new growth is susceptible to damage from a little insect called the citrus leaf miner. The tiny larvae live and feed inside the newly developing leaves, causing them to grow deformed.
The damage looks worse than it is. There's nothing you can do about the current damage. But, there may be more flushes of growth later. You can help reduce damage to that growth by spraying with spinosad. Click here and go to the 'Problems with Foliage' section to read more on the citrus leaf miner.
