This is one of the MOST important considerations when maintaining Ceanothus (or any type of shrubby natives) - branch dieback due to exposed cuts! We always paint open cuts ~1/4" diameter or greater to prevent entry by Eutypa lata (apricot dieback) either from direct water spray on the wounds, or Argentine ants swarming the sap wood. You often see conjecture about why peoples' natives are dying, when the real reason seems completely unknown. PLEASE SHARE.
