Gardening with the RHS

Insects are drawn to them, poets and artists are inspired by them, and without them, much of our agriculture simply wouldn’t exist. Flowers are one of nature’s most remarkable inventions, and in honour of British Flowers Week, we’ve got three fantastic floral stories. Georgie Newbery, artisan flower farmer and passionate advocate for the British cut flower industry, joins us to share how years of campaigning is giving flower growers a stronger voice and greater visibility at a national level. We explore the sweet pea extravaganza at RHS Garden Wisley this week with National Sweet Pea Society President Roger Parsons. And finally we tackle one of the biggest challenges facing gardens: aphids. Josie Stuart from the RHS Plant Health Team explains how to keep these sap-sucking squatters under control using flowers, while maintaining the natural balance of the garden.

June is when many kitchen gardens begin to hit their stride. Horticulturist, author, and YouTuber Huw Richards joins us to explore the joys of growing your own food, the benefits of self-sufficiency, and why gardens of every size can have a big impact on people, communities and wildlife. Huw also shares details of the Top of the Plots competition, celebrating inspiring growers across the UK. RHS Wisley's Liz Mooney reveals what you can still sow this June, from reliable favourites to more unusual edible crops. And as gardens buzz into early summer, RHS Science and Horticulture Editor Olivia Drake investigates lavender, our Wildlife Wonder Plant for June, and reveals which varieties prove most irresistible to bumblebees.

The highlight of the horticultural calendar is back. This week, we’re bringing you the very best of the RHS Chelsea Flower Show.

Growers and exhibitors from the Great Pavilion share their favourite plants, must-see showstoppers, and expert tips on everything from getting the most out of your hostas to creating natural dyes at home. We also meet Joe and Laura Carey, designers of Addleshaw Goddard: Flourish in the City, to explore London’s rich botanical history and discover how even the smallest urban gardens can become truly striking spaces. Plus, we take a look at the cutting-edge horticultural science showcased at the GreenSTEM exhibit.

We’re diving into the fascinating lives of moths with RHS Principal Entomologist Dr Hayley Jones. She tells us what sets them apart from butterflies, and how to set up nighttime nectar bars to give them a helping hand. We’re also turning our attention to a firm favorite in the garden: Hydrangeas. RHS horticulturist Jack Aldridge is a woody plant expert, and he joins us to share some of his favorite cultivars and everything you need to know about caring for your hydrangeas at home - from pruning tips to the secrets behind the brightest blue blooms. And finally, with RHS Chelsea Flower Show just around the corner, RHS Head of Libraries and Exhibitions Fiona Davison joins us to reveal more about the unveiling of a striking new botanical painting, known as a ‘Royal Signature’.

To celebrate Earth Day, we’re looking at how we as gardeners can make small changes to benefit the world around us. Nick Turrell and Jenny Laville will be digging into the topic of food waste, exploring how composting and changing our habits can make a big difference to our ecological footprints. RHS horticultural advisor Jenny Bowden offers an alternative, biodiversity-friendly approach if you find a traditional wildflower meadow just doesn’t work for you. And RHS Garden Wisley’s Liz Mooney and Pavlina Kapsalis share some inspiration for the veg patch, with some unusual crop suggestions you definitely won’t find on the supermarket shelves.

This week, we’re shining a light on some of the plants and creatures that play a vital role at this time of year: the ones that truly make spring what it is… starting with an often overlooked but invaluable contributor to the spring display - comfrey. Olivia Drake will be telling us more about this powerhouse for pollinators that deserves a place in any garden. Next, we turn to the veg patch and one of the most satisfying crops you can start sowing right now. RHS Wisley’s Liz Mooney joins us to share some practical tips on growing carrots successfully. And finally, we’ll be taking a closer look at one of the UK’s most beloved native mammals, now beginning to emerge from winter hibernation: the hedgehog. Hedgehog officer Grace Johnson from the Hedgehog Street campaign talks us through the challenges these charming creatures face, and how our gardens (however big or small) could hold the key to helping reverse their decline.

This week we’re embracing the arrival of spring in the garden. RHS horticultural advisor Jenny Bowden applies a right plant, right place approach in her sandy, drought-prone garden in southeast England. Embracing experimentation, she’s creating a resilient, low-maintenance space that shows even challenging conditions can thrive. We’ll also be celebrating the breathtaking displays of blossom unfolding across the UK right now, as RHS expert Jonathan Newell joins us to explore the rich variety of flowering trees and shrubs in bloom, and what makes this time of year so special for gardeners and nature lovers alike.And to round things off, our resident veg growing affionado Liz Mooney returns with another allotment favourite: this time turning her attention to cucumbers.

With the first glimmers of spring starting to show through, this week we’re diving into the theme of wellbeing – both for us and our garden wildlife. RHS Science & Horticulture Editor Olivia Drake joins us to explain why the common primrose is an essential early source of nectar for pollinators. We’ll also be exploring the powerful role gardens can play in our own health and wellbeing. The RHS has just launched a new science-backed Wellbeing Blueprint, designed to help anyone create a garden that actively supports wellbeing. Ashby Sachs and Vicky Shearing, who worked on the project, join us to talk about what the research reveals, and how we can all put those insights into practice. And finally we’ll also be dropping by the World Food Garden at RHS Garden Wisley, where edibles expert Liz Mooney will be showing us how, where and when to sow peas for a great harvest later in the year.

This week we join gardener and biologist Benny Hawksbee in his rose beds to find out how one small adjustment to the traditional rose pruning method can create vital habitat for a key aphid predator. RHS Garden Wisley’s Liz Mooney tells us about her journey to self-sufficiency, and horticulturist Rose Holman guides us through how to cut back your ornamental grasses before the new growth comes through.

This week, as its delicate catkins unfurl on bare branches, Digital Science Editor Olivia Drake introduces this month’s RHS Wildlife Wonder plant — the hazel – which not only supplies queen bumblebees with much needed early pollen, but also provides tasty nuts and abundant leaves to support a huge range of wildlife throughout the year. And while it may still be a little early to sow most crops directly outdoors, if you’ve got a greenhouse or warm windowsill you can get a head start on the growing season. Down at RHS Garden Wisley, Liz Mooney is busy sowing aubergines, sweet peppers and chillies, and she’ll be sharing her top tips for getting the best from these heat-loving crops. Finally, Professor Ross Cameron from the University of Sheffield – author of Plants Can Save Your Life – joins us to explore the science of plants and wellbeing, and how indoor gardening can play a powerful role in boosting our health.
