depending on the application.. fine mesh netting.. fishing line.. rubber bands.. really depends on what plant your useing and the type of wood your attaching it to as well.
I am trying to tie anubis and java ferns to a piece of drift wood I found. Not sure the type. It just seem I cant get the plant tight enough around the wood for it to look right.
Ah.. chances are it won't "look right" until the root system kicks in and actually grasps the wood. tying it to tight tends to cut-off the plants growth and too loose... bloody stuff falls off. which is partially why a nice peice of wood w/ a plant already rooted to it goes for a pretty penny usually. it's time. I prefer rubber bands for java fern myself slipping the band over the tuber chain part and then slipping it snuggy to to wood. depending on the growth about 2 monthes you cut the rubber band off and the plant settles in nicely. better to leave it to long then not long enough.
