On this week’s “Gardening in
Georgia
,” host Walter Reeves shows
how to control annual and perennial fall weeds. The show will air
at 7:30 p.m. on Wednesday, Oct. 24, on Georgia Public Television.
It will be rebroadcast at noon Saturday, Oct. 27.

Fall weeds can be grouped into perennials, which sprout from
their roots every year, and annuals, which come up from seed.
Reeves points out some annual weeds, which can be controlled with
a preemergent herbicide that keeps seeds from sprouting.

Perennial weeds like nut sedge and wild violets are harder to
control. Often the best technique is to dig up the plant, roots
and all. Reeves uses his handy Water Weeder,
Product No. AL829
from Lee Valley Tools, to unearth the roots
of perennial weeds.

Wasted Space Below

A deck above usually means wasted space below. Ginger Burgess
shows co-host Tara Dillard how to tackle that space below her
deck. Sealing her upper deck created a dry ceiling for a lower
deck.

It’s surprising just how functional her new potting space is.
Adding chairs and tables, with a ceiling fan to come, has turned
an unused area into a usable patio room/potting shed.

Reeves is angry! He’s discovered Asian ambrosia beetles in his
prized flowering cherry tree. The beetles bore into the trunks of
susceptible trees and deposit a fungus that clogs the trees’
water transport tubes. Half of his tree is already dead.

Asian Ambrosia Beetle Trap

Plotting revenge, Reeves shows how to build a monitoring trap. He fills a
plastic film cannister with denatured ethyl alcohol and inserts a
cotton wick in the top. He puts the cannister in the bottom of a
large plastic cup with large holes in the sides and water in the
bottom.

Beetles attracted to the scent of alcohol fall into the water and
drown, indicating that it’s time to renew the insecticidal
protection on nearby trees.

“Gardening in Georgia” airs every Wednesday at 7:30 p.m. It’s
rebroadcast every Saturday at noon. A Web site provides
further information. The show is produced especially for Georgia
gardeners by the UGA College of
Agricultural and Environmental Sciences
and GPTV.
