Q.What Are Fuzzy White Spots On Trunk Of 40 Yr Old Wisteria?

Zone Provo, UT 84604 | Anonymous added on August 29, 2021 | Answered

1st yr trimming new growth daily so canopy is thinner than usual. Very hot month. Recently added new wiring to lift weight of heavy branches. 3 distinct trunks. Never noticed the fuzzy white patches on trunks/thick branches in 30 years. Few leaves on top yellow with brown spots. Do not want to lose this beauty.
