At the back of the house, there is a brick structure which I believe were destined to be dog kennels. Unfinished, the walls are about four foot high forming two bays with an open front that looked very much like compost heaps I had seen in a grander garden somewhere on my travels. Of course that is exactly how I have utilised them.
The windfall of having a structure that might as well have been purpose built for composting is additionally sweetened by a ridiculous amount of available organic material. The grass gets cut twice a month which is a couple of feet's worth in one of those bays. Then trimmings of sugar cane, banana and papaya trees and miscellaneous garden cuttings supplement the kitchen waste of coffee grounds, vegetables, fruit trimmings etc. The supply is prolific. I even have the choice of occasionally dragging a neighbours bag of grass or trimming from outside.
I don't even turn it. Days of hot dry sun and then soaking tropical thunderstorm make the decomposition process intense and it is year round. Once one bay is full, I start filling the next and halfway through, the first bay is composted and ready to be used.
I use the layer just above the compost that is not quite ready but has started to break down as a 'nourishing mulch' for the plant beds in the Potager which are closest to this heap. I might mix this with some dried leaves too. The compost I then use in the specific areas I'm planting or mixed with some top soil for potting. The compost is a rich dark chocolate cake which I just marvel at and harvest so to speak in roughly three month cycles. I can't quite believe how ridiculously easy this is now that I 've got into a groove with it.
I avoid putting weeds in there although the grass cuttings may unintentionally include some and a friend advised against any kind of citrus that has bactericide properties that can slow down the process. Once while helping myself to some of that luscious dirt with my hands I scooped up a gigantic grub, possibly a rhinocerous beetle. I don't ever do that anymore with my hands.
I also have an unofficial compost heap outside these bays, against one of the walls. Here I do put weeds and turf and twiggy branches that I can't be bothered to strip of their leaves but no kitchen stuff and I leave it for a longer time. I started doing this because I didn't really know what to do with all of that and discovered that after a year, it composted just the same, but with a little more woody bits that need to be sifted out.
I use this other compost when I'm planting a new bed, turning it in deeper so that there is less chance of weed material having any effect. My guess is that with a longer breakdown, it's less likely to happen. Although, I'm beginning to not worry so much about this as weeds from blown seed is so prolific that the real game is in making sure there's a good amount of mulch and some kind of weeding goes on before they get out of hand.
Its a good job that I do have this resource because the soil here is incredibly clayey. At first I followed the lead of the locals in leaving it that way, as plants seemd to do fairly well in their gardens but then they also do a lot of watering (that clay gets hard when its dry) and a lot of fertilizing. I have since learnt to manage better by reverting to a soil mix that I've learnt with experience is pretty much an ideal growing medium - sandy loam.
