Host Walter Reeves looks at sprayers, trees and rocks in pots on
“Gardening in Georgia” July 2 on Georgia Public Broadcasting.

“Gardening in Georgia” is produced by GPB and the University of
Georgia College of Agricultural and Environmental Sciences. It
airs each Saturday at 12:30 and 7 p.m.

On this week’s show, Reeves shows what to do when your sprayer
gets clogged. It’s simple to unclog the nozzle so it will spray
what you want where you want it. He shows how to best clean
residue from the sprayer, too.

Reeves uses a fallen tree to prove the error of the deep-roots
myth about trees. Then he reveals how “included bark” eventually
caused the failure of a 100-year-old oak.

After Reeves points out the damage they do, you’ll never want to
put rocks in the bottom of flower pots. A better way to promote
drainage, he shows, is to support the pot on rocks placed in a
saucer underneath.

Finally, Reeves shows how to change the color of hydrangeas from
blue to pink or pink to blue. It’s all a matter of manipulating
the soil to change the pH.
