Wind is one of my biggest problems. Laden with salt it damages my plants, evergreen leaves are shredded in winter and most trees grow at 30 degrees to vertical. This year I cleared a new part of my garden, hoping to grow more perennial vegetables and useful shrubs in lee of Sycamore trees. I decided on a whim to create mini berms, about 18 inches from ridge to base, parallel to the wind direction (prevailing winds generally from SW), to give a bit of shelter. This also gives more shady/damp and well drained/sunny areas (hopefully!), however this autumn I noticed that they collected the sycamore leaves really well.
Sycamore leaves caught in depressions.
I wasn't sure whether the leaves would just blow away in the first gales, but we've had several slightly windy days up to 40 or 50mph and the leaves have now rotted away leaving their leaf stalks only.
Captured leaf stalks all that remain.
We usually have 80-90 mph wind most winters, and I guess if these occur before the leaves have decomposed, then I'll lose more leaves, but I'm pretty impressed how effective a small depression can be. I'm also surprised how quickly the leaves have decomposed, about three months max between first and second picture.
