6 weeks ago I tried an idea I've been thinking about after putting in willow fences straight from cuttings placed at 45 degrees and woven into each other.

So I trieed this concept on a urban "storm water drain" seasonal water course now.

So by simply pushing in the cuttings to a depth of 150mm or more the willow is almost certain to strike roots and create a living fence across the water course and build a leaky weir. Even when there is a flood event the fence will simply collapse and regrow by the looking at the other willows after flood events

below is a photo taken the other day, 6 weeks after the fence/living weir was put in. Will keep posts coming as the concepts grows
