Gardening with the RHS

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.

Ornamental grasses

This week, we’re heading to RHS Garden Wisley to discover how its horticulturists are turning one of the wettest starts to the year on record into a garden that’s primed for spring. Team leader Helen Bensted-Smith shares some top tips for gardening in persistently soggy conditions, and explains why increasingly wet winters and dry summers are challenges we need to adapt to rather than battle against. Guy Barter takes us on a seasonal stroll through Oakwood, which is coming into its own at this time of year, and has plenty of take-home ideas for gardening in damp shade. And finally, we popped in to see Liam Anderson, who’s hard at work pruning the 75m Wisteria Walk. In just a few months, it will be transformed into a spectacular tunnel of cascading purple and white blooms.

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.

RHS Grow Your Own

Now is a great time to start planning what to grow, and this week, we’re diving headfirst into the seed catalogues for inspiration! We’re exploring some of the tastiest, and most eye catching, additions to the veg patch: heirlooms! We also take a deep dive into tomato cultivars, as Liz Mooney shares her top picks from last years 'tomato extravaganza’ which saw her grow more than 50 varieties at RHS Wisley's world food garden. And finally, let's get back to basics with the foundation of any abundant veg plot: the soil! Nick Turrell and Jenny Laville dig into the ins and outs of how to care for earth beneath your feet.

This week we’re telling the story of peat: from the value of this amazing otherworldly habitat, to the threats facing these rare landscapes and work being done to protect them, and how growers and horticulturists are adapting to a peat-free future. We’ll be speaking to Beth Thomas from the Yorkshire Wildlife Trusts, RHS Peat-Free Research Technician Scott Spriggs, and plantsperson Mairi Longdon from Tissington Nursery.
