Congratulations! Add a water feature ... it will attract birds. And next to that some smaller shrubs. Then once the trees grow you can put climbers and ferns in them. And throw down some rocks for good measure. It encourages variant microclimates which encourages biodiversity.

Also throw down some Psylocybe Allenii spores (family Hymenogastraceae) for even better measure!

It thrives in otherwise hideous and tacky Home Depot woodchip landscaping beds in front of luxury yuppie condos, banks, and other nondescript, bleak looking buildings.

They'll lift the veil on your own bullshit, and make you deal with whatever's harming you, like four weeks of therapy in four hours.
