Quick situation explained: we bought a property with around the edges a water draining ditch that lets rainwater flow away. During the winter months its filmed with water constantly(for about 5 months), after that its dry unless theres rainfal. We have sown grass in it to prevent heavy erosion. My neighbor has a 400ft woodshed that has no gutter and the water falling off the roof is destroying the ditch. We used concrete plating to try and prevent the erosion, whuch works but is a bit too expensive for the entire ditch...
my thought now was planting willow trees on the eroding edge, every 6 ft, pollarding them so they dont get too big, and weaving willow branches between the trunks(horizonally), filling up one side with dirt. So the branches should theoretically root and start shooting and i could treat it as a hedge, pruning it yearly.
What do you guys think of that? Would it work? Would the willow thrive with the 5 months of being submerged? What will happen with the horizontal branches when they start to get thicker?
I will add a picture of what i kinda mean, but with living willow branches and poles instead of dead
