My wife and I are in the middle of a debate with which we seek some
guidance.

We live in Nairobi, Kenya. In our yard is a large, mature fig tree
(specific type unknown) under which we set up an outdoor dining area.
Quite lovely on balmy nights, except for the fact that there are
frequent, large drops of colourless odourless fluid going 'splat' on
us, our diner and our pets. To all intents and purposes this fluid
appears to be water, but we have no evidence of this (no, I haven't
tried tasting it!). The rate of 'splatting' seems to have increased in
the last month or so, but as we've only been in this house for a year
we cannot tell whether increased splatting is a seasonal occurrance.

My theory is that we're experiencing some sort of normal exudation
from the tree - I see references to 'guttation' and wonder whether
this is it? Our splatting happens morning, noon and night, whereas
guttation is described as morning occurrance, but then maybe that's
accurate for indoors-in-North-America and not for
outdoors-in-Africa...

My wife's theory, supported a recognized local tree expert, is that
some sort of aphids infect the tree and the splatting is a side-effect
of the damage they're causing. Remember, these are *large* drops we're
talikng about, and if that's aphid urine then I'm not keen to taste
it. We don't see obvious sign of aphid damage on fallen leaves.

Third confusing factor - as we come up to the rainy season there are
now also quite a few large (4cm) hairy black caterpillars falling
(again, spacific type unknown) from the same tree. Maybe their
predations are causing the 'splatting'. Maybe they're attracted by or
hatch from eggs laid near to the splatting fluid's source. Maybe
they're completely unrelated.

So:
- is this type of dripping normal for some/ all types of healthy,
mature fig trees?
- is the dripping a sign of some nasty infestation that we should be
treating aggressively?

Thanx in advance


In Southern California, there are two.

Normal drops from a ficus, tastes sweet, loaded with sugar.

the other, from a glassy winged sharpshooter, a type of leafhopper.
no taste, just like water.

Nothing much to do bout either cause.
