First early and second early potatoes should be ready to dig up this month, when they’re about the size of a large hen’s egg. With these types, they don’t store well so it’s best to eat them sooner rather than later to enjoy their taste. This is also an ideal time to prepare to plant potatoes so you’re ready for Christmas Day.
Plant them at least 10cm deep, adding more soil on top of the plants as the top continues to grow. Keep the plants well-watered and fed with a general-purpose fertiliser.
