The late-blooming, erect blackberry, Shawnee, and the thornless blackberry, Navaho, bloomed after the freeze and produced a good crop. Navaho suffers from some cane disease problems in south Georgia, however. Two mayhaws, Saline and Turnage 57, bloomed after the freeze and had a good crop. Most of the native mayhaws bloomed too early, though, and froze out. Muscadine grapes are one of the few fruit crops that produced a full crop almost everywhere in 1996.
Muscadines are much like pecans.
They have a low winter-chilling requirement, but a high heat requirement to start growing after they've gotten enough chill hours. This allows muscadines to always get enough winter chilling but bloom out after the danger of spring freezes. Pears are another foolproof fruit. Most bloomed too early last year and froze out. However, the old canning and preserving cultivar, Kieffer, had a partial crop.
