The 3 bay composting system was set up last spring assisted by the brother-in-law who provided 10 old pallets. (Thanks Francis!). I have just read Goff Lalor’s article ‘Dreaming About Perfect Compost’ in the winter issue of Crann, Ireland’s tree magazine. Goff fills the outside bays alternatively, tipping the contents of each in to the middle bay to finish the composting process in turn. This sounds like a good method which I’ll try out. Always happy to learn new horticultural tricks!
In my case, the tumbler composter sits beside the 3 bay system collecting and aerating kitchen waste. Meanwhile the first bay collects the old garden greenery, cabbage stalks, rhubarb leaves, hedge clippings etc. In the second bay, I layer the rejected garden material from the first bay with the softer kitchen waste from the tumbler. When the second bay is full, I fork it in to the third bay to continue composting. This leaves the second bay free to fill up as before once more.
The third bay has now yielded its first batch of reasonably well broken down compost. It’s not as attractive as Goff Lalor’s photo sample. However, it will do fine as a soil conditioner in the newly dug beds and
