When we cleared the orchard, my job was to chainsaw the trees and reduce them to manageable lengths. We ended with piles of stacked cherry and recently decided to use them as log walls separating the orchard and the vegetable garden.
The wood may eventually be burned, but while it dries it is great to look at and useful to invertebrates, small mammals and birds.
Here's Mike and Jake building the third of our short walls.
To give it a 'lived in' feel I'm placing little offsets of Sempervivums in the tops of the walls- they'll look great if they establish.
And I've planted ivy cultivars - Hedera helix 'Tripod', 'Ceridwen' and dwarf 'Anita'. Wrens and robins will love chasing small spiders through the foliage as the plants begin to climb the log wall.
