Answer: Citrus trees are sensitive to too much water. They like moist soil, but not standing water, so your trees may be showing signs of stress from the record rainfall. If you amended your sandy soil with organic matter prior to planting, then the soil should drain quickly, yet retain just enough moisture to make the tree's roots happy. Use a 2-3 inch deep layer of compost or aged cow manure over the root zone, and replace - or add to it - about three times a year. Otherwise, use one pound of actual nitrogen per year, per tree, divided into about three applications: February, June and August.
