Cleistocactus strausii
The cactus prefers free draining soils, strong sunlight, but not high temperatures — in fact it can withstand hard frosts down to -10 °C. In its natural habitat it receives plenty of water during the summer, but almost none over the winter. In cultivation, watering too much in winter often leads to root rot.
Cactus plugging
Cactus plugging is the practice of vandalizing or destroying a cactus, usually a saguaro, for fun. The Extension Office of the University of Arkansas says that the activity usually involves an inebriated person shooting at a cactus until it falls over.
