The time to prune grapevines is from January through the first of March, when the grapes are dormant. There are two types of grape pruningâcane pruning and spur pruning. Mature plants should be pruned yearly to remove all growth except new one-year-old fruiting canes and renewal spurs. Grapes are produced from buds that will grow into shoots on one-year old canes.
The first thing you need to do when planting grapevines is to make sure the soil is good. Clear out the area where you want to plant, then make sure the soil has good drainage yet sufficient moisture. Growing grapes requires a soil pH of 6.0 to 6.5. You can also mix in organic matter so the soil contains two to three percent. This means spreading 20 pounds of nitrogen per acre.
