Although citrus trees are evergreen, the oldest leaves do eventually yellow and drop off. But they are quickly replaced by healthy new leaves. So if just some of the inner leaves are yellowing, it's because of the natural shedding of older leaves. If newer growth is yellowing, it can indicate overwatering or a need for fertilizer or iron (or both). Citrus should be fed 3-4 times a year with a specialized citrus food, in amounts as recommended on the label which will depend upon the size and age of your tree. If you soil is alkaline, which I suspect it is, you can use Ironite to help green it up. Again, apply in amounts and with the frequency as recommended on the label. Best wishes with your tangelo trees.
