Wisterias need full sun, which we presume you have. They like to be in moist, well-drained soil that has been fortified with peat moss or leaf mold. If your plant is young, give it a general-purpose fertilizer in the spring. If it is mature, give it a complete fertilizer, such as 10-10-10, in the spring. If you’re in one of the northern zones, use pine boughs or leaves to mulch your wisteria in the fall for protection through the winter. Prune established plants to encourage flowering. Do this in late summer by removing new growth to above the sixth or seventh leaf from the base of each branch.
