September, being the prime harvest month, brings a lot of material for the compost heaps. Leafy greens aren’t a problem but things like sweetcorn stalks and brassica stems can be difficult. The answer to a good hot heap is a shredder. Shredded material will heat up and rot down far, far faster than un-shredded.
I once shredded a pile of privet hedge clippings and went in for tea. Being a nice evening I went back out to put them on the compost heap and the pile was already steaming and hot in the centre!
I use an electric shredder which copes and it’s easy to wheel or even carry up to the compost bins. Of course you need a power supply but we’ve a heavy duty, long extension cable.
Without a shredder the best thing to do with brassica stems is to wallop them with a lump hammer to crush and break them before placing at the the base of a heap. They can take 2 years to finally rot away.
For things like sweetcorn stalks, which aren’t as tough as brassica stalks, you can cut them into small lengths and spread them on the lawn. Then run over them with the mower and it will chop them like a shredder. This works well for hedge trimmings too.
