Answer: You can use Ironite for your citrus trees in amounts as recommended on the label. The amount you use will depend upon the size of your trees, and the frequency is generally every 3-4 months. The package label will explain in detail. Citrus trees take a lot of water so if you have a drip system you may need a single 2 gallon emitter, or several (again depending upon the size of your trees) and you may need to water for 30-60 minutes 2-3 times a week during the summer months. Wish I could be more specific, but frequency of watering really depends on the size of your trees.
Best wishes with your citrus trees.
