Owner is tearing out our gardens and putting in grass and river gravel

We chose this building because we were allowed to garden there. Have been here for 10 years. I am chronically ill and unable to work so we are low income. I have $25/month to spend on myself and for the past 8 years have spent most of it on plants.

4 days ago we got a notice on our doors that the owner has decided he wants a more uniform look, and will be replacing everything with grass and gravel. I just wanted to share my garden with someone before it is gone.
