In this one I’m having a proper honest chat about Jerusalem artichokes, because they can be brilliant… but they can also take over your plot if you don’t go in with your eyes open. I’m sharing my 10 biggest mistakes from growing them on the allotment, the sort of stuff you only learn after you’ve dug the same bed three times and you’re still finding tubers. If you’re on a budget like me, the last thing you want is a “cheap crop” that costs you loads of time, space, and effort to control. I cover the big lessons: where you plant them, how you contain them, why harvesting properly matters, and what happens if you leave even tiny bits behind. I also talk about planning ahead—because once they’re in, they’re in—and how to grow them without them bullying everything else. The takeaway is simple: you can grow cracking Jerusalem artichokes and get a great harvest, but you’ve got to treat them like a permanent resident and manage them from day one.
