It’s spooky season, and what better time to investigate three garden topics that are indelibly linked to Halloween. Pumpkins are everywhere, carved into grizzly expressions and displayed outside homes and workplaces. If you’d rather eat your home-grown pumpkin than scare people with it, RHS grow-your-own guru Liz Mooney offers a perfect pumpkin masterclass. We love all wildlife in our gardens but as it’s a spooky special, let’s talk bats and how to encourage them into our plots. Bat expert John Pearse reveals all. It’s Liz Mooney’s second growing guide of the episode, this time it’s a seasonal vampiric bulb, garlic of course. And we’ll round off the episode with listener questions answered with Gareth and Jenny Laville.

As the weather cools and birds flock back to gardens, many of us enjoy putting more food out for them. But have we been feeding birds all wrong? How can we help our feathered friends without inadvertently endangering them? RHS Senior Wildlife Specialist Helen Bostock tells us how to feed birds properly this winter. After an incredibly tough summer for turf, many domestic lawns are still feeling the effects of months without rain. It might be time for a reboot, so RHS turf and lawn care specialist Jim Millward talks us through how to turf properly and tells us about his team’s progress on returfing alongside Wisley’s famous Jellicoe Canal. It’s off to RHS Garden Hyde Hall to talk with Sarah Wilson Frost about mulch; what is it, why is it important, and what does it do? And we’ll round-off the episode with listener questions answered with Gareth and Melissa.

Meet one of our most loved and hated native plants. You might think of ivy as a destroyer of buildings or a nuisance weed, but it’s actually just been crowned the most popular flower with pollinating insects in an 8 year study by the UK Pollinator Monitoring Scheme. It’s also the RHS Wildlife Wonder plant for October, so our Science and Horticulture editor Olivia Drake is here to explain what makes it so valuable, and worth including in your garden. Staying with plant wonders, did you know if you dream of cucumbers, it means you might speedily fall in love? RHS Head of Libraries and Exhibitions Fiona Davison offers fascinating tales of vegetable folklore for an upcoming online seminar. Hyde Hall’s Andy Tebbutt tells us why autumn is the best time of year for planting, but what’s happening to that plant when you put it in the ground? And Gareth Richards and Melissa Mabbitt answer your gardening questions.

So many jobs to do at this time of year, but not enough time! As we rush to garden centres and nurseries, you can make it easier on yourself by narrowing down your new plant choices to those which are ultra wildlife friendly. Pollinators will always appreciate a helping hand, and a good place to start is with a new RHS guide, Plants for Pollinators. One of the authors, RHS entomologist Josie Stuart, is on the podcast to talk about what to plant now to boost wildlife diversity. If edibles are more your thing, Guy Barter offers sobering news on the future of Britain’s favourite brassicas – is it the end of the line for cauliflowers? And we continue our guide to essential jobs to do in autumn, this time it’s why and how to divide perennials.

While many garden plants have struggled for survival this summer, one which has truly thrived is the lantana. Horticulturist David Hurrion was one of the judges of last year's lantana trial at RHS Garden Wisley in Surrey, and he joins us to share his takeaways of growing these eye-poppingly colourful bedding plants, and some of the standout cultivars. 

Deadheading is a practice key to ensuring repeat blooms throughout the summer, and RHS Horticultural Advisor Nick Turrell shows us how to do it properly. And finally, as we enter autumn, we’re kickstarting our bulb of the week series with horticulturist Gemma Burr who shares some favourite coronet tulips from another recent RHS Plant Trial. Plus answers to listener questions on bay trees, lawns from seed and Salvia 'Hot Lips'.

Even though it's still August, the signs of autumn are starting to show. False autumn is a survival-driven stress response where trees shed leaves and change colour prematurely due to extreme heat and drought, and you may find yourself doing the autumn jobs a little early this year. 

We dive headlong into seed collecting with RHS horticulturist Lucie Rudnicka, plus find out how best to prune your trained apple and pear trees with RHS Garden Wisley’s fruit tree expert Jim Arbury. And finally, we relish in the joy of wildflowers with our very own Gareth Richards, as today sees the publication of RHS Wildflowers: A Pocket Guide. Plus we answer questions from the listener inbox on late sowings of salads, raspberry pruning and hornets.
