Thanks for posting this Laurence London.

I have asked the Danish Designer of these systems how do they "stop the Willow roots from clogging up the "spreading system"? 

His response is below and may be of interest.

Hi Laurence

Thank you for your interest of the willow systems that I have developed in 1996.
Your question is difficult to explain short. But they do not clog spreading system if the system is dimensioned very exact, the right system for spreading is used and the rigtht cover of the system is used. And they do not penetrate the membrane egihter. It is a question of balance between water amount and nutrients more or less. If the willow have enough water and enough nutrients and they are cut down in correct cycle the growth of roots are very limited. Only roots this as sewing treat is developed.

Best regards

Peder
