Second treatment this year. Sprayed as herbicide label had not included injection. They hope to inject next year. Without a spray boom they were only able to spray edge which seems ineffective - note flowering lush plants a few feet in from the edge. Spoke with Jasmine from PG who also mentioned difficulty of finding a local contractor to do the work. Note also the edge got mowed... bad. Will now be spread somewhere else. Also, opinion was that it was oversprayed, so was less effective as tops die before herbicide is transported into roots. Still, at least there is some effort to get on top of this problem. Need to ramp it up though.
Not sure tree type so I took picture of both trunk and leaves. Maybe chestnut? Leaves look dessicated for April
