Gardeners’ World star Adam Frost on what to sow and grow in autumn

As autumn approaches, it’s a good time to think about what fruit and veg you want to sow and grow for this year and next.

Adam Frost, a landscape designer and regular on BBC Gardeners’ World, will be sharing his gardening insights with visitors at Malvern Autumn Show but says there are problems with timings because of climate change.

He says: “The problem with growing veg now is that we haven’t got a clue – that’s the reality. We don’t know if winter’s going to arrive in November or December.

"My whole approach to veg gardening has become even more experimental than it was in the first place.” Despite this, he says: “Autumn is the time to think about the framework of your veg garden and if you want to add any fruit to it.

"It’s not long after that you can start to buy bare-root fruit, the currants and the raspberries.

“They are going to arrive bare-root but you can probably still get the back end of the containerised plants.”

He offers some tips on what to start off in autumn.

Rocket, for example. “I’d still give rocket a go because we live in a changing world and going into September and even early October, there’s still some warmth in the soil and you could still get a decent crop.”

As the season continues you may have to protect rocket plants with sheets of horticultural fleece to keep out the cold and you should be enjoying it through the cooler months.

Then there are broad beans. “In October I sow broad beans indoors in little modules in peat-free compost. Grow them up to a couple of centimetres before planting them out and you should get an early crop in spring.”

If you sow them in October, put horticultural fleece over them once you’ve planted them out to protect them during the coldest months, he advises.

“They might just sit there over winter or they might grow – it just depends when winter arrives,” he says.

Onions sets and garlic are among the easiest veg to grow, even if you want to grow them in containers, he says.

“Just be wary if you have wet soil, especially with garlic. I’m lucky as I live in a very dry part of the country but if you live in a wet area you might be better off waiting until spring.

“Alternatively, take a gamble with some in autumn, putting gravel underneath the sets to aid drainage over the winter months.”

Quick-return crops are another idea.

“In September, there’s still a lot of warmth in the soil, there’s plenty of moisture and we are still having warm days.

"So quite a few quick-return crops like salad leaves and radishes will turn around quickly.

"The way that things have changed so much gives us opportunity.”

Asparagus can also work – you can actually plant this at any point from autumn to spring.
