Growing & Maintenance Tips for Wisteria floribunda 'Caroline'

Wisteria will do well in an average to moist, well-drained soil in full sun or part shade. Pruning should be done soon after flowering, to ensure bud set for next season's flowers. In the summer months, continual pruning of the new shoots will help maintain a tidy size and appearance. Wisteria needs a sturdy support structure to allow for their vigorous growth habit.
