As promised here is an update on the squirrel situation. After spending $8. on moth balls, (and they don’t come colored), these herbivores continue to eat the plant stems. The smell of the moth balls have not detered them! However, I now have a new problem. Since the garden is outside my sliding glass door the smell of the moth balls permeates my condo and it will take a month for the smell to dissipate.
Henceforth, flowering bushes will be my only purchase. The squirrels have won.
