Next door neighbor has started a "pile".

What do u do with your grass cuttings?

He could use the contents of the heap as a mulch.

As long as he is keeping to his own property you are probably best not complaining.

It will kill trees by suffocating the roots. Its much the same as waterlogging.

You can mulch around the base provided you don't over do it. I take a "pile" to be over doing it.

ah now, this is a wind up is it? Your neighbour just has a compost heap. it’s a sustainable way to garden. Better than burning the place down anyway. If he is mixing grass with soil it will break down and he can reuse it.

As long as there isn’t meat in it, it won’t attract rats more than anything else in a rural area.

The answer is to just talk with your neighbour.

Here some people say it will attract and others say it won't. So if its an annoying issue for you just speak to the neighbour.

Planting trees too deep does damage them, trees top roots are usually exposed, it ring-barks them.

However, this doesn't seem to be happening, this is just the neighbour composting his clippings.

You could plant a hedge on your side of the wire fence.

It will hide the "pile" and the wire fence.

With the neighbour's trees growing behind your hedge it will look quite attractive in a few years.

The problem with putting a hedge on the other side of it is the hedge will probably die when its poisoned and smothered by what is in effect the silage effluent.
