Look over your kiwi vines in late January to early February. Thin out the vines by pruning them back to just the main vines that come from the base of the plant. Prune the excess growth where it branches off from the main vines, using pruning shears.
Prune again in the summer months after the vine has flowered. Any growth beyond the flowers can be pruned back. Shear off any shoots that have curled or tangled.
Cut back any new growth that is covering over the year-old shoots that produce fruit. It is important that they are not blocked from receiving sunlight. Continue pruning in this manner throughout the growing season.
