Lawn clippings only mulch

gutties

I have been collecting lawn clippings for about 10 years, all in one large pile - the new clippings go on top every time.

I haven't dug into the middle of the pile, but I would assume that the clippings would be well broken down.

As there is nothing in the pile but lawn clippings (apart from some leaves that would be in with the clippings in October) would these be OK to use as mulch.  I'm not certain whether near 100% lawn clippings would be good for a border / planting area.

Edit - should have said that my soil is very heavy clay

yes they'll be fine, quite rich compost under the pile i would imagine, in fact you can use fresh lawn clipping as a mulch around shrubs and perennials, no need to rot them down

Do you use a feed and weed type treatment on your grass? There may be some residual weedkiller if so - I have no idea how long it takes to completely disappear.

If not I agree it should be fine to use. I would only use the well rotted stuff. I've used fresh clippings as a mulch and ended up with lots of grass growing in the borders.
