Hi

Thanks for all the URL's. However, I could not find a reference to citrus
leaf miners.


[snip]

Actually, leaf miners shouldn't ordinarily be an overall threat to a citrus
tree. Normally they're an appearance problem only. When a homeowner's tree
of 15-25 years age goes into decline, it frequently is one which is
receiving too much water over a prolonged period of time. A young tree can
agressively put out new roots to replace those that succumb to root rot (too
much water) Eventually, as the tree ages, the roots start losing ground to
the rot and the tree dies.

If the tree is a dooryard tree or in your landscaping (and your lawn and
landscaping is doing OK) then the citrus is getting too much water. A St.
Augustine lawn requires much more water than a citrus tree can handle over a
period of years. If this is your situation, if you can close off any
sprinklers near your citrus and remove any mulch you may have around the
roots (out to the drip line) you may be able to dry out and save the tree.
