DESCRIPTION
OF PEST 
Spanish moss is an epiphyte (a plant that grows on another plant, but
not as a parasite). Epiphytes use the host plant only for support. Spanish
moss is a true flowering plant and will produce tiny, yellowish-green
flowers in late spring to early summer. Plants produce seeds which are
wind-blown and may lodge in bark crevices where they germinate. Spanish
moss does not produce roots, but has small overlapping scale-like leaves
which trap water and airborne nutrients. This plant grows along the
coastal plains of the Southeast.
Spanish moss does not directly harm
other plants, but may indirectly cause problems with weighting down
branches or shading out foliage. Plants that are less vigorous may have
a larger population of Spanish moss due to the increase in sunlight
to the branches where it is hanging.
