Grass fermenting in wheelie bin

Hi,
First, I found it difficult to select the correct section for my question.

2 years ago my wife and I moved into a just built bungalow for retired people.
Being rented there are one or two parts that are not up to standard.

The lawn at the back consisted of a pair of wellington boots, one army type boot,
stones of all sizes and broken glass. After a "fight" lasting 6 months to get it fixed the garden people dug down about 6 inches removing some stones and glass then sprinkled grass seed over it.
Last year we had no problems with the lawn, nor did we up untill 2 weeks ago this year. The lawn is about 40feet x 40feet.
2 weeks ago I cut the grass and put it into my wheelie bin, the bin was 1/3rd full. A few days later I cut the grass and that filled bin to 3/4 full. On the bin emptying day my wife left out the bin for the bin people to empty.
I went to bring it in and I was very surprised at the heavyness of it so I looked into it. There was what looked and smelled like manure at the bottom of the bin. It was almost a solid mess. I eventually got it out and I cleaned the bin.
Last week I again cut the grass and put the grass in the bin. 3 days later I cut the grass, put the cut grass in the bin, next day the same mess. This time my wife and I put the stuff in plastic bags but left them open untill "bin day" then placed them in the bin when it was emptied.
I asked around if anyone had any ideas but none had. Yesterday I drilled some small holes in the bottom of the bin, I cut the grass and put it in the bin but I did not ut the lid on so as to allow any possible water or fluid from the grass to evaporite. This morning I looked in the bin and the grass had started to ferment (if thats the right word). I emptied the bin and spread the ferminting grass on a small part of the lawn.
I've just had a look at the grass I put on the lawn and its drying out, slowly, but it is drying.

Could anyone offer any solutions please, Its a longish post but I included all of the above to aid in a solution - if there is one.

 

It is rotting without sufficient oxygen, and so is fermenting. It will make for smelly, slighty acidic mess, before eventually settling down to be slightly acidic compost.

If there is a patch of garden that is not currently used, you could dig the grass clippings into it, where they will break down nicely and return their nutrients to the soil, but the best bet would be to stick it in a compost bin/heap. If you do the latter you'll need to mix in 'browns', like old paper/cardboard, which will soak up some of the moisture and at the same time add carbon rich material to the mix, to encourage a good balance of the bacteria that breaks it all down.

The trick is, not too much grass clippings in one go. You can layer it (a couple of inches of grass, then a couple of inches of other stuff or soil, then a couple more inches of grass etc), but don't end up with too much grass in one mass if you know what I mean.

 

Grass will initially turn into a sludgy mess wherever you put it in bulk. You could spread it over flower beds as a green mulch but don't pile it too thick. I have read that it can help prevent black spot on roses used in this way. Or you could leave the collector off the mower and let it reduce down on the lawn. Councils do this with common and park land and it seems to disappear quite quickly.

One of my maxims is that nothing green leaves my garden.

 

The kids next door had better choose the colour of the footballs very carefully then

 

If you mulch the grass cuttings into your lawn you may encourage moss growth. I use grass cutting for covering beds when they are not in use, then dig it in ready for next year. Seems a shame to waste it.

 

OK Lads,
Many thanks for your great replies. Good solutions to try.

On the day I joined this fine forum I cut the grass, and thinking about it, I put the cut grass on a small area of grass and soil beside my shed, that in turn is near one end of the bungalow, I spread the cut grass on there in more of an experiment than anything else and I raked it from time to time. It was drying out nicely untill yesterday afternoon when the rain started.
I'll leave it there and put it in the wheelie bin on Tuesday evening ready for bin emptying on early Wednesday morning.

I'm considering taking the cut grass container out of the mower and letting the cut grass lie on the lawn as mentioned above, we have a 1 year old short haired Border Collie that loves us throwing "toys" on the lawn for her to run after, so she will scatter the cut grass.

All suggestions are in my little notebook for serious consideration, again, many thanks.
