Well today I got hold of a pump and drained the pool. It’s now awaiting purchase of some huge black bags so it can go away properly for the Winter. It’s going to need a good old fashioned cleanout before I fill it up next time though!
I’m really not happy with the state of the garden though, the mud is beyond belief. I’llÂ probably leave it fallow next year, unless I can sort out some decent drainage or other non-earth based surfacing.
