I put terra cotta watering spikes in two of my planters yesterday.
The idea is to put the hollow spike into the planter
down to ground (dirt) level
and then put a wine bottle full of water, upside down into the spike.
This morning when I left the house
I found one planter pushed off the porch
and the bottle broken on the porch and the walk.
I suspect an animal did the damage, most likely a raccoon.
