This week we’re bringing the garden indoors and welcoming in the Christmas cheer. RHS Horticultural Advisor Jenny Bowden will be sharing her love letter to the tradition of the Christmas wreath, and Freddie Garland – founder of Freddie’s Flowers – will be sharing his tips on how to make your own (among many other seasonal crafts to get stuck into). And finally, we’ll be learning all about our favourite festive parasite, mistletoe, with Oxford PhD student and mistletoe expert Oliver Spacey.

And we’ve got the perfect gift idea to brighten up a dreary January day, as Chris Lane of Witch Hazel Nursery explains why he fell in love with these winter gems.

We’re marking National Tree Week, an annual celebration at the start of the tree planting season, and an opportunity for us to wax lyrical about the wonderful world of trees. We’ll be hearing some fascinating stories about the art of tree collecting and the human connection to our woodlands from author and artist Amy Stewart. We’ll be catching up on the latest news from RHS Garden Rosemoor as they set out on a conservation project to protect one of our most rare but little known native trees. And if you’re feeling inspired to get outside and start digging, Bob Askew will be bringing us his thoughts on the best trees for small spaces.

This week we explore the fascinating stories and brilliant work of three exceptional plantswomen. Only recently has pioneering 18th-century herbalist Elizabeth Blackwell received proper recognition for her work A Curious Herbal – a beautifully illustrated botanical text that was, for centuries, mistakenly attributed to her scandal-prone husband! Fiona Davison, Head of RHS Libraries & Exhibitions, shares insights into Blackwell’s life and her groundbreaking work, which was created at a time of rapid botanical discovery in Europe as exotic plants flooded into the Western world. We also hear from passionate plantswoman Jane Steward, a dedicated advocate for the medlar, a rare fruit that was once beloved across the UK – even by King Henry VIII. And finally horticulturist Sarah Wilson-Frost from RHS Garden Hyde Hall will be sharing some excellent advice on growing ornamental grasses to add year-round interest to your garden.

This week we find out how to help our beloved prickly friends, as RHS Senior Wildlife Specialist Helen Bostock explains the threats to hedgehogs, and what we can do as gardeners to support them. Next we head indoors to find out how tailoring your potting mix can give your houseplants a new lease of life, with the lovely folks at Soil Ninja. Finally, if you’re looking for an autumn project, why not build some raised beds? We glean some expert advice on how to go about this, with RHS horticulturist Peter Adams.

This All Hallow's Eve, we’re venturing into the woods to see what treasures we can find… First up, one of the gardeners' most feared garden inhabitants is stirring. We’ll be chatting with RHS Senior Plant Pathologist Jassy Drakulic to find out about the notorious honey fungus, and how you can protect your beloved plants against infection. Next we’re stopping off at RHS Garden Rosemoor’s edible forest garden, which is based on one of the oldest forms of land use in the world. We’ll be catching up with horticulturist Peter Adams to hear more about this ancient method of permaculture. Finally, if you’re looking for a new addition to your spooky plant collection, look no further than the Aeonium 'Zwartkop.' With its dramatic magenta-black foliage, this striking rosette-shaped succulent is just one example of the remarkable diversity in colour and form within the aeonium genus. We’ll be finding out more, with the help of National Plant Collection holder Mellie Lewis.

This week, Gareth Richards and Guy Barter discuss the science behind autumn colour, why some years are more dazzling than others, and what we can expect to see across the UK this year. RHS Horticultural Advisor Jenny Bowden will share a Love Letter to her favourite tree that promises to shine bright at this time of year and has a distinctive smell that would tempt anyone. We head to northeast Scotland, to explore an RHS Partner Garden - Gordon Castle Walled Garden - to find out what visitors can expect to see at this time of year, and to find out more about the history of one of the UK’s largest kitchen gardens. And we hear from the RHS Garden Wisley trials team about the results of this year's lily-flowered and fringed tulip trial and ask what we should be planting this autumn for a great display next spring.
