Older, but no wiser

Problem
One - trees have grown so thickly together up at the more untidy end of the garden that they’re intertwined and giving so much shade the grass around them has given up growing.
But if we chop down the trees we’re left with a huge pile of branches to get rid of.

Two - both halves of the compost bin are full and one is ready for use on the garden.
But we’ve spread so much over the years that the beds are getting higher and higher and wont really take another six barrowloads of compost without overflowing.

Solution
Cut down the trees (an elderberry that never bore much fruit, unlike it's much more prolific neighbour down this end of the garden, and something else of whose identity I confess I'm unsure), clear the scrappy shrubby area beneath them, use sections of the thicker branches to make a suitably rustic retainer for the compost-enriched soil, plant the area with new shrubs, and chip the remaining smaller branches to make a moisture-retaining, weed-inhibiting mulch to spread between them.

Voila!
