Buckingham Garden Centre is holding its Potato Weekend on February 16 and 17.
The event will kick-start the new Grow Your Own Season and celebrate the potato.
The centre is linking up with The Puzzle Centre to raise funds by encouraging all gardeners to grow a single potato tuber in a container and see what weight of tubers they can produce by mid-September for a £2 donation. There is also a marrow growing contest.
The weigh in will be at the centre’s Potato & Chilli Weekend, September 21 and 22.
