Larry,
Guttation is due to root pressure. The required conditions are moist to wet growth media (soil or potting mix) and relatively high humidity, as often occurs during the night, when the opportunity for transpiration (evaporation from leaf surfaces) is low.
The droplets of guttation occur at the edges of leaves of many kinds of plants. It is seen early morning, before the atmospheric humidity begins to drop. The "remedy" for guttation is to dry out the air -- perhaps as easy as turning on a circulating fan in a greenhouse or solarium.
Wet lawn grass in the morning could be caused by guttation but is also (possibly more commonly) from an overnight dew.
Bottom line: guttation happens; not a problem.
Hope this helps,
Jean in Portland, OR
I?ve got a small philodendron here in the office, which Pam started
for me over a year ago. Amazingly enough, I haven?t killed it, and
it seems to be doing pretty well in an office with little natural
light. But, I?ve noticed that sometimes when I water it, the leaves
start ?sweating? - a drop of water appears on one or two leaves.
It?s the weirdest thing. I?ve not heard of a plant doing that. Am I
watering it too much?
