We have a Chinese wisteria in our courtyard. We suspect it is at least 40 years old. It has bloomed beautifully for the past 19 years (since we moved here). We built a pergola to hold it. . . it's magnificent. However, this year we had hard freeze in April (zapped the buds, but that happens every few years). We had no flowers, and have very few leaves and it's mid June. We are heartbroken that it may be dying. We could prune it back, and hope it will revive itself. Do you have any hints about what might be wrong? Our local folks here in northern New Mexico don't have a clue.
