Groovily, they're showing "The Victorian Kitchen Garden" on "Yesterday" (the TV channel that used to be UKTV History). My dad used to love that programme. He had them all on video, along with a huge number of programmes about steam trains. Wonderful person though he was, he really did love boring things on TV.
Actually, though, it's really quite fun to hear elderly gardener Harry Dodson demonstrating how Victorians kept the earwigs off their peaches. I might have to tape it myself.
