Things Needed
Only a few varieties of American labrusca or non - labrusca bunch grape and some French / American hybrids grow well in South Carolina ’s quick humid summers . South Carolina ’s climate divides between the northerly mountains and Piedmont areas , and the sand hills and coastal plains . grow conditions in these two region do n’t prefer the same grapeshot cultivars . Problems include fungal diseases of fruit and foliage as well as Pierce ’s Disease , a bacterial contagion . right pruning of disease - immune variety increases the quality and the amount of bunch grapes and decreases price from fungi .
Step 1
Train new planted vines to a individual - wire treillage by set aside two or three cane to turn vertically along a sustenance stake for the first summer . pick out the first to touch the cordon wire , about 5 feet from the ground , and disregard back the other canes to the ground .
Step 2
Cut the leader or trunk cane just past the first cane node above the cordon wire . Tie the cane to the support billet .
Step 3
Select two side shoots to become cordon or ramification the undermentioned bounce as the year ’s newfangled growth sprouts . Choose cane that join the automobile trunk about 8 inches below the support wire and train them to either side , tying them loosely to the cordon conducting wire with garden twine . Cut off all competing shoot .
Step 4
Allow both ramification to spring up 60 to 65 column inch to either side of the trunk and then trim down back to 48 in . Cutting back the main arm encourages side shoot to grow . Remove cane that sprout from the top of labrusca cordons . Rub off any flower buds during the 2nd year of growth of either labrusca or non - labrusca grapes .
Step 5
Prune labrusca vine during the following winter to select firm downwards - lead canes . Choose canes 4 to 6 column inch apart on the cordons and prune compete canes back to the main branch . Keep canes on the top of non - labrusca cordons , thinning to the same spacing as for labrusca .
Step 6
disregard back labrusca canes to pull up stakes only four to six bud per cane . Trim non - labrusca varieties back to one to three bud per fruiting gad . Leave four to six buds on fruit canes of intercrossed vines .
Step 7
Train fruiting canes to grow downward in an open airy curtain in the 3rd twelvemonth . Comb or roll out the vines to grow with an even spacing . Allow no more than one bunch of grapes for every two cane .
Step 8
Prune mature vines each winter to select new fruiting canes at the right spatial arrangement . swerve out old canes which bore yield the previous time of year . Cut back cordon to 4 feet in length each wintertime . Allow mature vines to set no more than two clusters of grape on each fruiting shoot .
Tip
Always curve back any water supply sprouts or cane growing from the master trunk . Competing cane decrease public discussion and trim sunshine reaching the fruit parts of the vines . Clemson University recommends Concord , Delaware and Catawba as the best salmagundi for both domicile wine - making and brisk feeding in the Piedmont and mountain regions . Conquistador tops the leaning as a general intention variety for the George Sand hills and South Carolina ’s coast .
