Answer: This grape is winter hardy in USDA zones 7 through 9, so it may be that the plant is still becoming established in your garden or may need a more sheltered/warmer position. It will bloom and set fruit on new growth of the season, so pruning is typically done in late winter, cutting the plant back very hard to leave only a few buds. Do not prune it during the summer or you will be removing the current crop. Grapes do well in average soil and in full sun. If you think transplanting will be helpful, the best time to do so would be in late winter to very early spring.
