The garden is often a mess after the summer and needs a good clear out. This is generally a popular job. The greenhouse at St John's gets completely overgrown with plants that have finished growing for the year, including a very prolific grape vine. I've no idea what the hat was all about.
And there's often hidden treasure lurking underground. No matter how hard you try to pick things in July, you always miss something. Which then is a bit of treasure for the autumn garden clean up crew.
