Wisteria sinensis 'Alba' (Wisteria sinensis 'Alba') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Many years of leaf and no flower
Typical of seed-grown plants; buy a named grafted 'Alba' and prune twice a year to encourage flowering spurs.
Bud loss before flowering
Hard late frosts or ill-timed hard pruning remove the short spurs and swelling buds that carry the racemes.
Structural damage from vigour
Strong woody stems can crush gutters and trellis — provide a heavy-duty dedicated support and prune in summer and winter.
Yellowing leaves (chlorosis)
Iron deficiency on alkaline or chalky soil; apply sequestered iron and add organic matter.
