Name: Florence B.
Our magnolia tree (unfortunately I do not know the name
of the variety) blooms in the spring. It is now July and I noticed on
many of the branches groups of small balls, anywhere from three to six
(looking like marbles) enclosed in a netting. They seem to jut out from
the stem. I wonder what these may be! Are they harmful to the tree? Are
they buds? I also noticed a great deal of activity -- many, many bees
and wasps flying around from one limb to another. It is a very beautiful
tree and I would like to preserve it as best I can.
