HortWeek Podcast
'Not your usual garden' - a Chelsea 'finale' and showcasing the unexpected with The Newt's Katie Lewis and Harry Baldwin
Joining Rachael Forsyth the week's HortWeek Podcast are Harry Baldwin head gardener at the Somerset garden and estate, The Newt, alongside Katie Lewis, estate architect.
After four years as a headline sponsor at the Chelsea Flower Show, it is The Newt's 'finale' year and it is set to showcase tropical plants sourced from nurseries in the UK, South Africa, and from its own collection in its Karoo Succulent show garden, a collaboration with The Newt's South African sister farm, Babylonstoren.
As Katie says: "There will be plants in the garden that probably many will not have seen before, as well as some quite recognizable plants that people might have as houseplants. But they'll be able to see them set in what we're trying to evoke as their natural setting, so we're hoping that that's going to be quite inspiring and exciting for people."
But The Newt's relationship with the RHS will not end completely, Katie explains: "So we'll continue to be a partner garden and we'll continue to support the RHS."
Harry talks though some of the attractions and features on The Newt Estate, aka the Hadspen Garden. He explains the way the 40-strong specialist staff work - which includes dedicated garden and woodland teams.
New to the team is entomologist Tom Oliver who is instrumental to work The Newt is undertaking to understand, audit and improve its biodiversity. Tom's data will also be used to help The Newt experiment with new cutting regimes for the wildflower meadows to try and maximise the invertebrate life throughout the year.
Harry says: "We have a really rich biodiversity across the estate. I guess we're also quite lucky here because we've got different types of landscapes...we've got the woodlands, we've got pasture, we've got our formal gardens, and we've got quite a big range, which no doubt helps with the biodiversity."
The Newt is set to host a Head Gardeners Conference in October 2025 which will gather 100 head gardeners to discuss trees for the future.
Like all gardens The Newt faces challenges with pests and diseases and climate change and trees are central to these topics.
Harry explains: "native plants are important because our invertebrates have adapted ... to our native plants and our native landscapes. But it's obviously important that we do start to bring in some non-natives. For example, we've got one area ... where we've had to sadly remove a number of large ash trees because of ash dieback...So there
I'm hoping to planting native trees but also looking slightly out the box where we can planting, for example, we can plant a Caucasian hornbeam ...which is still going to service our woodland but it might have the added diversity of being able to be slightly more drought tolerant perhaps."
In keeping with it's lightly unorthodox approach, The Newt allows visitors to pick vegetables and fruit from its kitchen garden:
"The ethos of the kitchen garden is that for people to try - everything in there is completely edible and there is almost no boundaries... We want people to be immersed into our landscape, into our fruit and sort vegetable heritage."
And with her design hat on, Katie is keen to extend the spirit of experimentation and innovation at The Newt:
"I think there's ways that we can champion plants more, champion seasonality more, offer more to our guest experience in various ways.
"I want to really showcase plants that aren't necessarily purchased from your local garden center...I've had the opportunity to work with some really great, wonderful and unusual plants from various temperate regions of the world. And I really want to bring that to The Newt."

15. Can rock dust save UK soils and rock horticultural production? with Veolia's Jennifer Brodie
22:50||Season 6, Ep. 15Studies such as that of McCance and Widdowson have revealed dramatic drops in fruit and vegetable mineral content since the 1940s. This week's guest on the HortWeek Podcast Jennifer Brodie believes that 'rock dust', a by-product of volcanic rock mined for road construction and rich in minerals trapped since the pre-dinosaur era, could help reverse this by remineralizing the soil and feeding microbes that will re-fortify plants.Brodie has come full circle in her career and is now returning to her passion project 12 years after she founded REMIN (Scotland), which pioneered the use of rock dust as a top dressing for soil, compost mixer and activator.Now leading the Pro-Grow rock dust division for resource management company Veolia, she explains the geology behind basalt rock dust, its dual benefits for plant health and carbon capture, and how the industry is shifting toward "ecological transformation".She details how some of the 400,000 tonnes of green waste they process annually is integrated with rock dust to create a PAS 100-certified compost for the garden retail market. Her goal now is to expand rock dust's use into the organic farming sector.Quoting Soil Association founder Lady Eve Balfour, Brodie says: "Everything begins to matter when the rate of soil erosion exceeds the rate at which life can invade the mineral rock underlying the soil and convert it into soil." Brodie believes that rock dust has an "unrecognised" role in rectifying the mistakes of the past and helping renew soils for the benefit of all.Make sure you never miss a HortWeek podcast!

13. Linden Groves on why The Gardens Trust needs to remain as a planning statutory consultee
16:56||Season 6, Ep. 13The Garden Trust's Linden Groves is campaigning against a proposal to end the organisation's role as a planning statutory consultee.She robustly contests the proposal to remove the statutory consultee role and disagrees that it would improve the planning system. Instead, precious parks and gardens, hard won over many centuries, would be lost to communities both now and in future.“We are passionate about the role that the UK’s world-famous historic parks and gardens can play in supporting positive economic growth and healthy cohesive societies, and eager to continue helping this in our role as statutory consultee. We encourage supporters to respond to the consultation and will publish our response as soon as possible.”In March, the Government decided to ditch planning consultancy from bodies including The Gardens Trust, to speed up the planning system. “We are seeking views on reforming the role of statutory consultees in the planning system in England,” it said. The consultation closes at 11:59pm on 13 January 2026.The consultation can be accessed here.Make sure you never miss a HortWeek podcast!

12. Why tree guru Tony Kirkham wants to 'get rid of the term 'tree planting''
25:51||Season 6, Ep. 12Tony Kirkham has a mission, one that will resonate with many arborists across the UK: "I'd like to get rid of the term 'tree planting'".The former Kew arboretum head says: "Our success rate of establishing trees isn't good in this country... I'd sooner see less trees planted and established rather than planting big numbers that fail to establish." In his conversation with HortWeek editor Matthew Appleby, Kirkham gives his thoughts on the "exotics" versus "natives" debate and reveals his "top future trees" which include his favourite "hard-working trees".On pest and disease threats to trees, Kirkham issues a stark warning. Experts say it is a case of "not if but when" Xylella enters the UK, and Kirkham says, with more than 400 host plants identified so far: "I think every woody plant is vulnerable. We really need to crank up our biosecurity."Other than Xylella, his the top concern is plane wilt, which "is spread by arborists" via tools, machinery, PPE and clothing, and which is "coming towards us pretty quick...we need to keep that out at ALL costs".He also talks about how arborists can handle the rising frequency and intensity of storms, recalling how he got Kew back up and running in the wake of the storm of 1987 that brought down so many trees that he considered "old friends".But despite the devastation that took three years to clear, he now says it is "the best thing that could have happened" - getting rid of unsafe trees, giving the Kew team a chance to replant and refresh the arboretum, revolutionising tree-planting practice.

31:27||Season 6, Ep. 9The HortWeek Podcast has joined ArbWeek to bring HortWeek readers a series of interviews with leading arborists. The first of these is Jeremy Barrell.A influential figure in the tree care landscape (and HortWeek columnist) Jeremy Barrell is one of the leading authorities on tree care.A passionate campaigner on street trees in the wake of a number of controversial local authority fellings, in this week's podcast HortWeek editor Matthew Appleby hears Jeremy's uncompromising views on tree safety, tree planting, tree production and local authority procurement.Barrell says: "The standard of training on some of the people that are planting [trees] - it's not surprising the trees don't survive...if you don't have a specification that is up to scratch, then of course contractors are going circles around you and you deserve to have a load of failures". "I deal with more tree failure cases that result in harm than any other expert in Britain...the harsh reality is there are many large duty holders...that don't do anything like the standard of tree checking that should be done".
