Ask-a-Dave's-Gardener: Sick Wisteria, 1 by KDNimmo

Is my wisteria dying? New to gardening this year. Never had a baby wisteria. Leaves are turning yellow/orange and falling off. Some new green growth. Should I clip the leafless branches off, or will more leaves come? What is the best fertilizer? How often to fertilize? How often to water? Let dry between waterings or no? Replant in bigger pot yet? When should I put it in the ground? Any advice much appreciated.
