Thinking of Holland, I see a landscape of pastures and small paths between two ditches of water with on both sides rows of pollard willows. These willows are not only planted to hold the path firmly between the water, but for centuries, these trees provided farmers with sticks and wood for the garden, brooms, the fireplace, fencing, and other domestic functions.
It is a good idea to have one or more pollard willows in or close to your garden. Every one or two years it provides you with nice firm and flexible sticks for your garden, such as for bean stakes or partitioning. The thinner and more bendable twigs can be used in making a small wired twig fence (google 'making a willow fence' for some pretty ideas). Also think of great little green huts or arches! Every willow twig that is put in the ground, no matter how small or terrible you cut it, will grow and produces green leaves, and eventually more twigs to continue this process.
