Leaf compost

I had read somewhere that if you put fallen leaves into a plastic bag and store them, they will turn into compost. This time last year, I put leaves into a black plastic bin liner, made holes in it, put it into the shed. I looked at it recently and the leaves are still the same as when I put them in the bag - whole and wet. Why did they not decompose? henlen, , Co Kildare Posted: 12/11/2017

It is likely there was not enough air getting in. Also, the leaves may have been naturally soft, such as horse chestnut or poplar, and inclined to clump together, impeding aeration. Beech and oak are best for leaf mould. 

Make some more small holes and leave it for another year. 


Leaf mould making and tar spot.

I'm making leaf mould with sycamore leaves that have tar spot in plastic bags (with a few holes in the sides). Is it likely that the temperature will be high enough to kill the spores? If not, can I still use the leaf mould for young trees and shrubs? Inish, Fanad, Co Donegal Posted: 11/11/2016

The tar spot will likely rot in the compost. But there are plenty of spores around so if it survives, it does not matter.


Briquette ash

Can I add briquette ash to my compost heap, when it's cold ! Brayhead, Bray, Co Wicklow Posted: 05/03/2015

Peat ash has no nutrient or soil structural value, but yes, if you wish, to mix and spread it.
