Hi I have a rather neglected, very large hazel tree orchard. There are heaps of suckers that have grown up that are useful for stakes in the garden or whatever you can visualize. You'd need to cut them down yourself and be happy bending and fossicking under trees. The sizes vary from thin, bendy whips around 0.5 cm diameter, up to bigger rods around 2cm at the base, and up to 2.5 meters tall. These are estimates of course.
