How to grow vegetables in containers

Grow your own is a big theme of BBC Gardeners’ World Live and ahead of the show I talked to Matt Biggs about how lack of space needn’t be problem.

It’s easy to assume that to grow vegetables you need space – an allotment or a back garden turned over to spuds and carrots. That’s difficult with gardens getting ever smaller and waiting lists for allotments while those living in flats may have only a balcony. The answer, believes Matt Biggs, is growing vegetables in containers.

“We’re trying to encourage everyone to grow vegetables and this can be done irrespective of the amount of space you’ve got,” he says.

“Just because you have a small back garden you’re not excluded. Come on in and join the fun.”

Matt, one of the regulars on Radio 4’s Gardeners’ Question Time, will be exploring how to do it and what to grow in daily talks on the VegTrug Grow Your Own Stage at BBC Gardeners’ World Live.

It’s important not to think you can become self-sufficient in veg, he tells me, but to choose things that are family favourites, are difficult to find in the shops, or that simply taste better when they are freshly picked.

“Grow your favourite vegetables rather than the things you think you ought to grow,” he advises.

Fast maturing or what he calls “high value” crops are better than things that are cheap to buy or that will occupy the container for months – main crop potatoes and parsnips are just two examples of crops to avoid.

Keeping a note of what you’ve grown and what worked will enable you to build up your own list of what works well in your garden.

Among his top tips are carrots, beetroot – “pick them when they are the size of golf balls” – and lettuce, particularly ‘cut-and-come-again’. Sweetcorn would be another ideal crop as it begins to lose sweetness as soon as it’s picked.

Peas and mangetout are ideal for growing in containers

Other suggestions for vegetables in containers include mangetout, peas, runner beans, endive and chard, while Matt says strawberries are ideal for hanging baskets where they are out of reach of slugs.

It also makes sense to choose mini veg varieties or those that have been bred for small spaces, such as broad bean ‘The Sutton’. Look out also for those with disease resistance.

If you can’t get mini veg seed, just pick before the crops reach full maturity and sow again.

“If you harvest when they’re small, you get better quality, they’re more tender and tasty.”

The key to success when it comes to vegetables in containers is not to sow the whole packet at once but to keep repeating every few weeks.

“People do forget to succession sow and to sow a little and often,” says Matt.

When it comes to containers, anything goes as long as it has good drainage and is as big as space will allow. Try recycling old wooden boxes – line them first with polythene to prevent water loss – or hunt out some of the many colourful plastic containers on sale.

“I would avoid metal because it will heat up in the sunshine and will scorch fibrous roots and dry out the compost but apart from that you can just use your imagination and make it fun.”

Matt advised filling your containers with compost designed for vegetables, or making your own by mixing organic matter, such as homemade compost, with a John Innes soil-based compost to give it more substance.

Once planted, choose a sunny spot and check plants daily for pests, diseases and water – an irrigation system saves time and water. Then, just keep harvesting and sowing.

“Don’t be frightened to do it,” he says. “The lovely thing about gardening is it’s not failure it’s gaining experience. Always be prepared to have a go, learn from what happens and enjoy it.”

BBC Gardeners’ World Live 2017 is at the NEC Birmingham from June 15-18. There will be talks, growing advice, nursery exhibits and free entry to the neighbouring BBC Good Food Show. For more details, see the website.
