The back patio of a PHA house at 1606 Catharine St has a weed that's taking over our neighborhood!!! It has grown into a huge tree. Its seeds have dropped into other back patios nearby, which have created more undesired growth. The large leaves have made our back patios in the shade 24/7, killing plants and flowers and creating a mess. Please remove the source, the mother of all weed trees, growing behind 1606 Catharine. Thank you.
