COLD PROTECTION AND RECOVERY STRATEGIES
Muscadines are frequently
damaged when temperatures at or below 0oF occur. The following
are suggestions which may help to lessen or eliminate cold injury and
speed the recovery of the vines.
- Do not plant cold
tender cultivars in north Georgia and avoid them in middle Georgia if
possible. Do not plant cold tender cultivars on marginal sites (too
wet, poor soil, very low elevation, etc.) anywhere in the state.
- Prune cold tender
cultivars late in the winter.
- Do not overcrop
cold tender cultivars. Do not allow any cultivar to carry significant
amounts of immature fruit into the winter. This can be a death sentence.
Apparently, the immature fruit continues to "sap" the vine
even into the winter.
- Keep the vines
healthy by control of the grape root borer and retention of the leaves
with fungicides, proper weed control and proper fertilization.
- Do not wrap vines
excessively on the wire while training. The cold metal wire is a good
conductor of warmth away from the vine. (This statement is a supposition;
not a proven fact.)
- Cold damaged vines
frequently will lose one arm or a section of an arm. If pruning has
not been conducted prior to the cold injury, a long, vigorous "bull"
cane can be placed on the trellis wire after cutting off the damaged
Vines killed to the
ground will often resprout. Use milk cartons or some type of physical
protection around the vines after the new shoots emerge to prevent contact
