There seems to be no shortage of "sharp" things growing in a hot climate and these long sleeved, leather welder's gloves are just the ticket for tackling an unruly bougainvillea or thinning out vicious bromeliads. I found these at a yard sale ($1!), and they've proven invaluable.
The pantyhose/tights were given to me by the woman who runs my favorite thrift store. I cut them into smaller lengths and use them to tie orchids, ferns and small (friendly) bromeliads to palm and tree trunks. They stretch as the trunk expands and can be cut off when the plant has firmly attached itself.
