So, I'm thinking of making a dog poo composter in the garden. So far, the internet tells me that I need to dig a reasonably big hole in the garden and cover it with a plastic lid. The poo gets put in the hole along with a bit of dirt. Every now and then, it can be helpful to put some septic tank chemicals in there to help with the breakdown. I'm then told it is completely safe to use on the lawn and ornamental plants- just don't use it on veggies.
Is anyone around who can give me a sanity check on this? Do I have my facts straight? Any hints from people who have done this before/ already doing it?
Thanks!
