I have propagated and given away giant-leaf dieffenbachia (18" leaves) for
years. I keep my plants in the house year round.

In my house, they grow a single trunk until they reach the ceiling. I cut
them down and cut up the trunk, root the top and the trunk pieces, and the
original bottom still in the soil grows another single-trunk plant.

A friend who has one of my dumb cane progeny left it outside for the summer,
and just brought it in for the Fall. She called to say that it now has
beads of moisture around the edges of the leaves. That has never happened
in my own house. She also said that it has four new baby stalks shooting
up from the base, That is also something that I have never encountered.

What is going on. Too much moisture? Too much summer sun? Are the
drips safe, or are they severe irritants like the sap?
