Leaf miners? I don't bother trying to control them.
I use Sunniland Citrus granular you can get at Home Depot and other locations. 6-4-6 with micro's, every other month. Keep in mind that granulars get washed down really good with a good rain, which can drive the nutrients past the roots before they can use it. So if it's a heavy rain season you may want to replenish every month. On my small trees (1st year or two), about 1 cup per application. I use 2 cups when the trees are 3 years old or older. I also use this same fertilizer on my mangoes and bananas.


I also use a quality Peters water soluble with micro's as a foliar spray a few times per year, and as an occasional drench.
