The Organic Gardening Podcast

What do bed sheets, hessian and bacteria have in common? They might help us reduce the amount of plastic we use in our veg plots! 

Award-winning author, gardener, peat- and plastic-free advocate Sally Nex shares fascinating advice for reducing, reusing and recycling the 500 million pots, seed trays, and other bits of plastic we get through in our gardens every year in the UK.

“When we chip a pot and it goes directly into our soil, it's going to stay there for the next 400 years,” says Sally. “Experiments have shown that earthworms, which are living in soils high in microplastics, lose weight and soil biodiversity is a fraction of what it is in clean soils.”

Chris and Fiona chat about the delay in germination and plant growth due to the cool start to the summer – and reassure that it’s not too late to sow now. From the postbag, Anton advises on using organic slug pellets, and the team mull over what creature might be creating ‘strawberry piles’!

We’ve got a double bill this month to help you save more water in your garden over the summer.

We’re joined by Jo Osborn from the charity Waterwise – who tells us that in England alone, we face a potential water deficit of close to 5,000 million litres of water every day by 2050. She shares how crucial it’s we conserve more of it in our homes and gardens.

And climate change gardening guru Sally Morgan talks rainwater and grey water harvesting. She reveals ways to water plants more effectively, and the importance of soil health.

“No dig is important because we don't want to disturb the fungi in the soil,” she says. “Most plants have a relationship with the mycorrhizal that extends beneath the plant – and it’s this fungus network that does the watering for them, finding water in the soil.”

We'll be answering your questions about how to deal with box hedge moth, what to do about allotment-loving ants, and how to tackle chilies that are not hot.

In this month’s Organic Gardening Podcast, Chris Collins chats to Nick Hamilton – son of organic gardening pioneer Geoff Hamilton – and finds out more about his gardening journey and life at his beloved Barnsdale Gardens.

We’ve always had a close relationship with the gardens and Nick, a former Garden Organic trustee, and shared many planting schemes and plant cuttings over the years. Our ‘Paradise Garden’ (now part of Coventry University), with its pergolas and pond, was built to commemorate Nick’s father and TV gardener Geoff. 

More than 25 years ago, Nick had what seemed like an impossible task – taking over a collection of 30 or so organic gardens designed for television and turning them into a visitor attraction aimed at inspiring people to grow organically. In 2023, Barnsdale marked its 40th anniversary. 

“I don't have any problem with people referring to me as the son of Geoff as I'm very proud to be his son. The gardens are his legacy…and still rolling on today,” says Nick. “I want to continue to show organic gardening is not complicated or difficult - it's easy! And because you're working in tandem with nature, nature helps you along the way.”

Chris and Fiona chat about our Every Garden Matters research paper – showing small steps in any size garden can have a positive impact on biodiversity. And from the postbag, we tackle how to safely dispose of laurel debris and old garden pesticides, and discuss whether we should feed birds all year round.

Chris Collins chats to Josiah Meldrum, co-founder and owner of Hodemedods, about growing beans and pulses in the UK climate.

Josiah explains how Hodemedods works with British farmers to supply pulses, such as lentils and chickpeas, in as sustainable way as possible and often using organic methods.

He shares some varieties that can grow well in our gardens and how they grow more unusual crops such as chickpeas and lentils. He also shows how easy it is for British gardeners to overlook the multiple uses of beans.

“People miss a trick in the UK when it comes to runner beans. We tend to think of them as something you harvest green, but the rest of the world don't do that: they also dry them,” says Josiah. 

“In Poland, they've got a fantastic tradition of growing and harvesting these delicious white runner bean seeds…and in Greece, you'll have giant ‘Gigantes’. I would encourage everyone to save beans and eat them. The scarlet runners and the white seeded beans are absolutely delicious!”

Anton reveals how to grow ‘green chickpeas’, and whether it’s worth growing a crop of lentils. From the postbag, he discusses how to deal with moss on vegetable plots, and Chris and Fiona chat about the effects of the wet and windy spring.

To celebrate Food Waste Action Week (18-24 March), Chris Collins and David Garrett join Fiona to bust the myths around composting. If you want to know how, why and what to compost this is a must-listen.

David, our head of knowledge transfer at Garden Organic, shares the reasons he loves compost, and talks through the different composting systems at our organic demonstration garden, and how to use them.

“We're producing kitchen waste at home so why not process it ourselves and produce compost? It's a circular economy in our own homes,” says David. “We're taking ownership of the waste and not relying on someone else to deal with it for us.”

Chris and Fiona chat about what to sow and plant now and how to care for winter ponds. 

Our CEO Fiona Taylor visits Slimbridge to chat to Simon Rose from the  Wildfowl and Wetlands Trust (WWT) about ways to create similar habitats in your growing space. 

With 75 per cent of wetlands in the UK lost in the last 300 years, Fiona explores the importance of urban bluescapes and bogs as a homes for wildlife.

“Wetlands are really rich in wildlife – in fact 40 per cent of the world's species are reliant in some way on wetlands,” says Simon, who is Head of Experience Development at the WWT, which is based at Slimbridge Wetlands Centre in Gloucestershire. “But they also help prevent flooding and reduce carbon emissions. Wetlands are actually faster than rainforests at locking up carbon.”

Simon and Fiona discuss ways you can mimic these diverse habitats in your own growing space.

“Whenever you introduce water into the garden it's one of the best biodiversity boosters, and that could be anything from a bucket to half a barrel. Dig a hole, fill it with water, put some rocks and some plants in it and I guarantee that within weeks you’ll attract wildlife,” says Simon. “The sediment that settles on the bottom of a pond is another opportunity for carbon sequestration, even in a back garden setting.”

Chris Collins and Fiona chat about jobs you can be getting with this month, and Anton Rosenfeld delves into the postbag to help answer your questions. This month, they chew over using woodchip as a mulch, how to tackle rats, and ways to save money in the garden.

Join Fiona Taylor as she chats to Adam Alexander, aka the Seed Detective. Adam is a volunteer Seed Guardian for Garden Organic's Heritage Seed Library, and self-confessed seed nut! Adam shares stories of his travels around the world, and why seed saving and sharing is so important.

Our guest this month is Anthony McCluskey from Butterfly Conservation, who shares some fascinating advice about how to support butterflies and caterpillars in your growing space.

We chat to Butterfly Conservation’s urban butterfly project officer about the importance of attracting more butterflies and nighttime pollinators such as moths. And he provides some brilliant advice on things you can plant and do in your garden to help support pollinator populations.

“Recent studies show more than 80 per cent of our UK butterfly species are in decline and a lot of our moths are in decline too,” says Anthony, who is based in Stirling. “If you want to boost butterfly numbers locally, you need to pack your garden with ‘caterpillar plants’.”

Chris, Emma and Fiona take time to reflect on their successes and failures this year, and Emma answers questions from the postbag including how to plant wildlife-friendly hedges, tackle leek moth and improve soil in greenhouses.

In this month’s podcast, Chris hops across the border to visit the Royal Botanic Garden Edinburgh to learn more about its conservation work.

He chats to Kirsty Wilson, herbaceous supervisor at the botanic gardens, to discover more about its 350-year-old living collection of plants and its research projects.

Kirsty, a presenter on BBC Scotland’s Beechgrove Garden, explains the steps the garden is taking to help fight climate change, including preserving struggling plants, using green and clean technology and biocontrols for pests. 

“We're doing a lot of work conserving Scottish native flora, as well as plants that are dying out in the rest of the world,” says Kirsty. “It’s important to understand biodiversity and plant life – and the species that are struggling - so we can protect them…and raise awareness with governments.”

Chris and Fiona discuss the benefits of not being too tidy in the garden, and planting whips for hedging. From the postbag, we offer advice on what to do after tomato blight, ways to tackle invasive weeds and allium leaf miner.

In this month’s podcast, we chat to Pam ‘The Jam’ Corbin about making seasonal jams and chutneys from homegrown produce.

As the UK's leading expert on preserving, Pam shares some of her best-kept preserving secrets in October’s Organic Gardening Podcast.

Pam cemented her reputation as a preserving expert at Hugh Fearnley Whittingstall’s River Cottage. And in her latest book, Pam the Jam: The Book of Preserves, she provides detailed instructions for making more than 100 of her favourite recipes from classic pickles to savoury jams.

Fiona caught up with her at her home in the West Country to take a tour of her pretty garden, and find out why she loves to make the most of delicious garden fruit and vegetables.

Chris Collins and Anton discuss creating the right conditions for healthy grapevines, friendly ways to tackle box moth caterpillars, and box alternatives, and how to avoid plum tree rot.
