Aka, it could be a number of things, but the first thought that came to mind were spider mites. Inspect leaves/stems/branches..They're very small, most ppl can't see these tiny creatures..Most time they're discovered after they build fine webbing..finer than the common spiders makes. Usually during a mite attack, foliage turns yellow splotched color, then leaves pale as you're descibing.. Of course there are other pests that destroy foliage, too, like scale, mealy, aphids, etc. Check your citrus..Toni

What Mike suggest is exactly what I would do.lol Of course I have a weak spot when it comes to sparing sick plants of their demise. For some reason, it makes me feel good that I can handle such a feat. It's funny about me, but when I see a plant for sale that looks like h*ll, I tend to grab it and find myself having a good time bringing it back from such an aweful state. call me crazy if you would like. You certainly have to have the patience to accomplish such a feat and the know how. The know how will come from being a part of this forum along with persistence in learning. The patience, well, not everyone is up to that. The fact that you have green cambium tells me there is hope, that is if you are willing to look at such an ugly/ oops,cute tree if so that is what you choose to think of it.:-) Please make sure that mix is coarse enough to allow proper drainage and encourage much new root growth. Provide LOTS of sunlight and NO fertilizer until you see its first sign of growth. Make sure the mix you choose dries out evenly and rapidly. Mike:-)

Miracle grow potting soil actually is not much more than a bag of peat moss. If regular potting soils are used they have be admended with wood chips, CHC, cedar chips, pine bark or other coarse material to help increas the draining and root zone aeration. I know growers that have used Maricle Grow's Garden Soil with success, still I would recomend adding coarse material to that. . If you pull your trees out I'm sure you will find that your tree's root system are in real trouble. With all the water that Miracle Grow Potting Mix holds, the trees's roots must be starved for oxygen. -S-

I have tried neem oil on it and on my figs last year. problem with the chemicals is they do not get to the root of the problem. diatomaceous earth should kill anything live attacking it.
