For all your trellising needs. Our choice for an all-purpose string is this 2 mm thick hemp twine. Strong enough to support a staked tree or an 8 foot tall tomato plant, this beefy cord is made of renewable, all-natural hemp. At a 48 pound capacity and aesthetically pleasing shade, the generous, 265 foot roll comes in handy for more than just gardening. We’ve been using it for macramé crafts like plant hangers and woven pet toys.
