Double your potato harvest this season with this genius expert-approved gardening trick

Potatoes are one of the most popular foods to grow in the garden, and it can feel rather sad when you notice they're done producing for the season. However, with this nifty trick, you can prolong the harvest – which has never been more needed than now.

Whether you're vegetable gardening as a beginner or have a thriving allotment, getting more out of your plants can prove challenging. But to keep gardening costs low while still growing more food, there are ways you can utilise the plants you already have to produce extra fruit.

Potatoes are one of the best foods to grow in pots, providing fairly substantial harvests from a single plant. And with this genius advice from BBC's Gardeners' World, that's about to be doubled again.

If you chitted your potatoes at the right time, you may have been enjoying your harvested vegetables this month. And whilst that supply may seem like it's depleting, there is one thing you can do to prolong it.

"Here's a trick you might not know. That's what I'm looking for, a top that's nice and healthy, but with a load of tiddlers on it," says Toby Buckland, professional gardener and presenter on BBC Gardeners' World.

"See, this plant has got life in it yet, and if I stick this in some fresh compost it will regrow and give me another crop in 6 to 8 weeks," he adds.

"It's so simple, all you do is dig a hole in another pot of compost or in the ground, and then stick the spud in. A thing to know is that if you've got a spud with lots of tops on it like this one, just snap it off," shows Toby.

It's quite similar to how, when you prune tomato plants, they're able to redirect the energy used to grow foliage into producing more fruit.

"Got too much leaf for the amount of root that is left; it'll soon regrow what it needs. This trick works on all potatoes you harvest in the summer, the ones known as early or second early varieties," explains Toby.

"Main crop spuds that are harvested in late summer or autumn don't have time to regrow a second crop," he says.

Then when you've enjoyed that second harvest, you can easily remove the plants and prepare your soil for its next leafy inhabitants.

To ensure you've got another potato harvest next year, remember they're a vegetable that needs to be planted in April.
