I recently planted a bunch of seeds/flowers in pots and boxes on my back porch. I live on the second floor, so the porch is high up. The squirrels jump from the trees onto the roof, and climb down the drain pipe onto the porch. They dug through all the dirt in my boxes and broke one of my clay pots. I was pretty disappointed at the mess, but I still love the squirrles. I really don't want to kill or hurt them, does anyone know of a friendly way to gently discourage them from coming onto the porch and killing my plants? I've had the tree branches trimmed, but that doesn't stop them. They always seem to find a way to get on the porch!
