across much of north Georgia are forecast to fall in the low-20's or
below overnight. Please consult the Kirk
Mellish forecast for last-minute updates. Here are our thoughts on
the effect cold will have on our landscapes:
What will happen
annual flowers and vegetables outdoors will freeze. Goodbye to
the impatiens and tomato vines that were still hanging on in your
landscape or garden.
Winter annuals like pansies and ornamental cabbage will not be
harmed. Pansies will have wilted leaves Friday morning. This is a
normal reaction to cold and the leaves will be fine when it warms up.
Consider watering them Friday afternoon if the soil is dry where you
What you should do
- Turn off your
automatic sprinkler system!
- Bring topiary rosemary and your citrus plants
indoors from your deck or patio.
- Move hardy
patio plants like roses and "color containers" up close to the wall of
your home. Water them this evening before the cold hits.
- Most shrubs and trees will not be harmed.
Even the Knock Out roses that are still blooming won't be hurt,
although some of the tender twigs may be killed. This shouldn't be
cause for worry.
Marginally hardy plants like sago palm and oleander should be
protected. Also consider protecting about-to-bloom camellias with
swollen buds and 'Miss Huff' lantana.
There are a few ways
to protect plants
1. If they are low to the ground you can cover
them with an old bed
sheet. The cloth will usually trap enough of the earth's heat to
the plant is taller than three feet, consider "tenting" it with
plastic. Drive a tall wooden stake next to the center of the plant,
leaving the top of the stake higher than the plant. Drape black plastic
over the stake and the plant and anchor the edges of the plastic to the
ground with stones or firewood. (Black plastic is better than clear
plastic because it doesn't heat up as much when sunshine hits it.)
3. Remove the covers once temperatures have
risen above 40 degrees.
Good luck and good gardening!
