The 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.

Tony 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.

This is the second special podcast with an arboriculture focus produced as part of ArbWeek, HortWeek's deep dive into all things arb held from 24 - 30 November.

• Listen to Jeremy Barrell on how 'Failing clients deserve failing trees', plus tree growing, procurement, planting and establishment

This week's guests bring their distinct perspectives on the arb sector - but also bring a holistic perspective having worked together for many years on fascinating and crucial research projects.

Kevin Martin, head of tree collections at RBG Kew and Adam Dunnett, production and amenity director for Hillier Nurseries are thought leaders in their fields and bring fascinating insights and forthright opinions to their discussion with Rachael Forsyth.

They discuss tree planting and establishment, ground breaking research with "remarkable" results that is transforming tree selection and understanding of how to grow and in particular, water, trees.

00:52:43 Kevin and Adam's 'dream' pieces of research topics

On the topic of encouraging young people into horticulture, Adam Dunnett relates a "chink of light" following a visit to a secondary school where as part of their work on the "2050 project" they are looking at what trees will be thriving in 25 year's time.

"That's just one school, but actually that could be really quite transformational if that's happening in other schools!"

Kevin says: "Horticulture and growing plants is an applied science, and it's one fo the most important applied sciences we do and it's so overlooked...it's always been seen as suitable for someone who's not academic, and that's not the case.

"We need some of the brightest people to solve some of the biggest questions...we need to work on that narrative."

In this episode the Victorians get a couple of name-checks and we also get some top tips on which tree to go to to get unbeatable conkers.

Chloe Whiteside, ICL’s technical area sales manager covering Norfolk, Suffolk and Cambridgeshire – has spoken on the HortWeek podcast about the highs and lows of the 2025 spring bedding season and what the strong start and weaker finish mean for the 2026 bedding plant season.

She talks about what bedding growers should be doing in the lead-up to the spring season and gives advice about watering, nutrition and storage regimes for peat-reduced and peat-free growing media.

On nutrition, she talks about using controlled release fertiliser and water solubles, as well as which biocontrol, biopesticide and biostimulant products are at the grower’s disposal and, as a BASIS qualified adviser, what she recommends.

Before joining ICL, Whiteside spent 10 years in horticultural research at ADAS, delivering research projects on a wide range of ornamental and edible crops. She managed the AHDB funded Bedding and Pot Plant Centre trials, as well as the AHDB, Defra and industry-funded project on Transition to Responsibly Sourced Growing

Media Use in UK Horticulture. The project ran for five years and covered all sectors of horticulture, from bedding propagation right through to container grown trees and soft fruit production.

The 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".

Garden centre personality Rosie Bone brings her new ideas for garden retail to the HortWeek Podcast this week this week.

Founder of the World's End Garden Centre in 1970 with Len Bone, Rosie puts her success in garden retail down a focus on customer service, looking after your staff and above all "value for money". She argues if you get those three right, other considerations such as location are almost irrelevant.

She discusses her passion, which is sustainable garden retailing.

"Profit isn't a dirty word... but I think in this day and age we have to start to recognise that there is an environmental cost to everything any of us do".

She says that imports from China cannot be avoided in many product areas, but that carbon footprint could be offset by focusing on plant-based options in the restaurant:

"It's not about telling customers what they should and shouldn't eat, but presenting [food] in a way that encourages customers to make [a plant-based] choice for themselves but that can be done with clever marketing, clever menus."

After a period away from the industry Rosie reveals the garden business that revived her interest in and passion for it and what they do so well.

And she reveals some significant gaps in the market that garden centres, with their large footprints and nature-oriented client base, could capitalise on.
