In the back patio of 1606 Catharine St, there are several Jack & the Beanstalk weeds that have been growing for decades and have now reached an incredible height and weed branching that is dangerous for an amateur like myself to cut down. The leaves that fall from this tree are humongous and cover all our back patios, killing all our flowers. The leaves, pollen and golf-ball-size-pods are making an undesireable mess. I've written this issue numerous times to PHA and SeeClickFix with no action taken. This property is still owned by PHA, who just evicted the tenants who were there for many years. Any ideas on more effective methods before I chop it down myself?
