Here is a challenge. In my gardening I am trying to avoid costly chemical products and stick with as much organics as I can. However, there are a couple citrus trees at the back of our property that I have let the other half take care of as he sees fit since I know next to nothing about caring for citrus.
Anyway, the question is, how hard is it to take care of citrus trees organically and still get a harvest?
We have greatly improved the prospects for these two trees since we moved in by cutting down a large tree that was shading them horribly. And they have been sprayed a couple of times with chemicals which has improved several problems (like fungus/mildew and rust.) but we still notice leaves that have been disfigured by leaf miners. Not just trails but these leaves tend to be rumpled up as well. What works on leaf miners?
Also, for citrus what types of organic fertilizers work well? Most of my gardens are fertilized by deeply mulching with organic matter but citrus I understand should not be mulched as that could lead to root and trunk rot. This is also in very sandy soil where liquid fertilizers run away quickly. Any ideas?
