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.

The Biodiversity Net Gain market has come along way since BNG became mandatory in England under the Environment Act 2021. The ruling requires developers to deliver at least 10% biodiversity net gain for new construction projects.
In this week's HortWeek Podcast Rachael Forsyth speaks to head of sales and services Emma Hindle and head of business development Brian Smith at Ground Control, which provides ready-to-buy BNG units as part of a habitat bank.
They discuss how the market is developing, the drivers of demand, and shifting balance of supply and demand.
Although Government targets and policy for house building is driving construction projects, Brian explains that Ground Control is "not betting the farm on housebuilders" and is keeping it's client base deliberately broad, including utility companies, transport companies as well as corporate clients such as supermarkets. Interestingly, a burgeoning "voluntary market" is also part of the picture, he says,
But while developers might, understandably, focus on the immediate costs when deciding on how to approach BNG requirements, a 30-year maintenance lifespan means a "whole life" cost approach is more appropriate, he argues.
The market has come on leaps and bounds since 2021, Emma adds, insisting the focus should always come back to nature recovery and the "benefits for the country". Many that had reservations initially are now "taking it seriously", she says, and the prospects for BNG over the next five years are "amazing".

BBC Gardeners' Question Time stalwart and landscape architect Bunny Guinness returns to the HortWeek Podcast to give her views on some of the pressing horticulture issues of the day.
Topics covered include garden sector shows. Bunny wonders if there are too many that are struggling commercially. She expresses particular concern over RHS Chelsea Flower Show gardens and the lack of commercial sponsorship which she says is helping drive down design standards as well as the chilling effect that banning peat for RHS shows might be having on exhibitors.
A full YouTube convert and broadcaster, Bunny discusses why she thinks it is the best place for gardening content, a view given some weight by Alan Titchmarsh's recent migration to the platform.
And she talks about her path into horticulture and why she believes a 'landscape architect' career path offers more and better opportunities than that of a 'garden
designer'.

Good Gardeners International is a charity that since 1962 pioneered the no dig system in the UK, based on Sir Albert Howard's research on organic farming.
Richard Higgins became involved in 1995 after a formative trip to India and inspired by Howard, developed the HH-2 (Howard-Higgins Agricultural and Horticultural System) Waste Management and Horticultural System.
The HH-2 equipment reproduces specific fungi and bacteria that creates a sustainable habitat to enable the colonisation of the root hairs of plants giving them huge boots of previously unattainable nutrients. It claims, along with a unique, manure-based feedstock, to be able to renew degraded soils in one season.
Adoping a no-dig appoach complements this as keeping the soil intact protects the "mycorrhizae, and that is the network that feeds the nutrients from soil into the root hairs of plants. So if you don't dig, that's preserved."
Higgins explains: "[HH-2 is] a composting system that breeds fungi, specific fungi and bacteria. Now, ordinary compost doesn't do that; this system does, and it's this fungi and bacteria that makes plants so resistant to disease. I mean, we already cured slug snails and caterpillars 30 years ago!"
Initially marketed and sold to amateur gardeners, "it's so popular and farming today is in such a problem with soil depletion and pollution in rivers, etc., that we've blast into farming. It applies to farmers as well as gardeners".
He says a focus on 'new varieties' has stymied research into how soil conditions can impact plant health. GGI has a demonstration farm where, he says, "we've got universities, colleges, agricultural colleges queuing up to come and see it, because people don't seem to know how to stop these common agricultural pests. We don't use any supplementary feeds like comfrey or rhubarb leaves in... no nets for the black fly, white fly, carrot fly, you know. We don't use any nets at all and we have none of these problems."
Higgins discusses startling claims for treatments that could reverse the effects of ash dieback and says he is in the process of liaising with scientific institutions, agricultural research stations and soil scientists with a view to carrying out trials and scaling up production for wider distribution to amateur, and professional growers.

This week's guest is Guy Watts of West Sussex-based specialist plant nursery, Architectural Plants.
After a successful debut at RHS Chelsea Flower Show, Guy talks about Architectural Plants' apprenticeship scheme Home Grown which he hopes will encourage new talent into the industry.
The nursery grows and sells a huge variety of unusual and exotic plants, and in line with the nursery's aims to reduce plant movements within and without the UK, Guy talks about the nursery's innovative 'lab' which allows the nursery to propagate and grow plants that require more specialist conditions.
On biosecurity risks Guy has strong views: "Our evidence is that they are as likely to come from within the UK as they are from outside of it". And despite bans on chemicals increasing biosecurity risks, he reveals how the nursery has been largely chemical-free for some 20 years which has mitigated some of those biosecurity challenges. He outlines some of the systems and strategies he uses to monitor pests and diseases, some of the non-chemical treatments they use and how staff are involved in the process.
Guy also talks frankly about his perspective on going peat-free; the nursery is running trials and has reduced peat use, but Guy expresses doubts about talks of the RHS imposing "blanket ban" and he questions whether the alternatives are environmentally sound: "it needs to be the right decision commercially and it needs to be right for the environment".

Six months into her role as head of parks and gardens at the National Trust Sheila Das speaks to HortWeek’s Rachael Forsyth about the Trust’s new strategy and how it is taking a step back to re-evaluate its approach to planting, the “scarcity and abundance” of water, climate change, outreach, education, going peat-free and more.
Speaking on changes at Cliveden in Buckinghamshire – where The Long Garden redesign focussed on long-term resilience, moving away from bedding being changed twice a year – Das explains that the Trust won’t “eradicate” the presence of bedding but it might be done slightly differently. They will also evaluate where the plants come from, how they’re grown, the resources required to grow them, and the financial cost.
Climate change is being felt within gardens across the UK and Das said each garden within the National Trust will have to work to understand its own individual challenges, which will be done through workshops. On the specific challenge of water – both scarcity and abundance – Das says it’s important to be “mindful of the pressures we’re putting on our local environment through having a garden.”
A particular challenge the National Trust has, she says, is that certain sites are working to create an atmosphere and a particular type of plant might be doing that that isn’t going to work in the future climate. Working out how to keep the spirit going, cherishing the site's heritage, without depleting natural resources is going to mean “delicate decisions” balancing being “a good descendent as well as a good ancestor”.
The National Trust is 100% peat free in its gardens, but Das says “there’s no denying it’s a challenge” with gardeners unable to get all of the species they would like. She adds that the range and diversity of plants feels “fragile”. Suppliers are doing “a really good job” Das says, they just might not be able to move as quickly as everyone wants.
National Trust, in common with gardens and attractions across the UK, faces the challenge of falling visitor numbers and she addresses the various causes of this and outlines how the Trust's new strategy is looking at ways to “end unequal access” and “inspire millions of people”.
