Unexpected garden heroes (2 Dec)

Did you know that there are 30 different species of worm in the UK? Or that fungi can actually help create habitats for wildlife? This week we're exploring the roles played these crucial but often overlooked garden residents. Back indoors we meet a hidden hero of horticulture – ‘likely the most prolific botanical explorer of the early 20th century’. Staff from RHS Garden Wisley and the Royal Botanic Garden Edinburgh join forces to tell his story.

Cracking good kale and sloes to savour (25 Nov)

Learn how to grow winter veg staple (and superfood) kale with RHS expert Guy Barter, who recommends the tastiest and hardiest  varieties and explains how to keep problems at bay. 

There's also great advice on when and how to protect tender plants from frost by either mulching or wrapping, and chef and author Mark Diacono tells us how to beat the winter cold another way; by making delicious and warming sloe gin from the fruit of the blackthorn bush.

Totally tulips (11 Nov)

From smuggled wealth hidden in the pockets of 17th-century refugees to imperial beheadings and long treks up freezing, desolate mountainsides... there's more to the humble tulip than you might think. And as the nights draw in, now is the perfect time to get planting these spring favourites. 

Garden designer Humaira Ikram shares her favourite varieties and ways of using them, and we head to Cambridge University Botanic Garden to discover a unique collection of species tulips and talk about their origins. Plus historian Fiona Davison tells the tale of how tulip mania shaped the history of Europe and gripped the Ottoman Empire to deadly effect.

How green is your garden? (4 Nov)

You might think of gardening as an intrinsically green activity, but our verdant hedges and lush lawns can cause some very dirty habits. In an eye-opening interview, low-carbon gardening expert Sally Nex gives the lowdown on how ditching petrol power tools is important for the health of both gardeners and our planet.

Plus we head to COP26 host city Glasgow to discover a pioneering urban seed library that helps create resilience in local food systems. And in Cornwall we meet artist Dr Alexandra Daisy Ginsberg who's created an inter-species installation using an algorithm to create gardens designed from the perspective of pollinating insects, rather than humans.
