I've temporarily planted a very small lilac bush in a
pot with plans to transplant it to the yard in the fall.
(I'm in central Texas.) Until recently everything has
been fine, but now I'm noticing what appears to be a layer
of mold/mildew (green stuff) on the surface of the dirt in
the pot.

Is it a problem? Should I skim it off the surface? Should I
do something more drastic?


It shouldn't be a problem, but lilacs are notorious for getting powdery
mildew on their leaves. It isn't generally a fatal condition. I have some
lilacs that potted two years ago and never got around to planting. They are
doing very well in their tiny pots. I'm sure they are root bound. Maybe
this summer I will find them a good home.
