October is the time to think about making some leaf mould (or leaf mold - for my North American readers) - making good use of all the fallen leaves on the ground at this time of year.
I'm in the process of tidying up my little garden in St Ives, somewhat neglected after all the time I've spent on my allotment plot lately. My wife Jo has also put in a fair bit of work.
I've pruned the tree back recently, leaving me with several leafy boughs cluttering up a corner of the garden. So I've stripped off the leaves from those and collected up as many as I can find from the lawn and borders.
An obvious move might seem to be to add the leaves to the compost bin. But I've found in the past that these sort of "shiny waxy" leaves don't compost down very well. In any case - its not a good idea to add too many leaves - of any type - to your compost. A good compost bin has a roughly 50 / 50 balance between high nitrogen items (vegetable waste, weeds etc.) and carbon (cardboard, twigs, leaves etc.). So lots of leaves can tilt the balance too far to the carbon side.
Its better to rot down the leaves separately.
Final tip - if you've got large quantities of leaves - it might be worth building a "leaf bin" - simply made from four posts and chicken wire. Something that I might do later - on the allotment where I have more space.
