Bob Askew was Garden Media Guild award winner a year ago for his new writer work for Hortweek. He works for Kernock Park Plants as production director and was previously at Darby Nursery Stock and Brinkmans.

Here he names his top three tree genera for gardens, three underused tree genera and top five skinny trees for small gardens.

He believes the reliance of nurseries and garden centres on too few ornamental tree cultivars is a bad thing and is critical of overuse of Betula utilis var. jacquemontii and Crataegus Paul's Scarlet, and offers alternatives to them.

Askew also names three awful crab apple cultivars and five brilliant ones for gardens, as well as five brilliant but below-the-radar flowering cherries.

He delves into the pros and cons of growing trees in solid pots, versus airpots, or slotted pots.

This week the HortWeek Podcast meets Imogen Bell, supervisor at Thomson's Garden Centre and a YPHA Southeast regional coordinator

In her article for HortWeek 'Despite CITES, not all doom and gloom for houseplant sales' Imogen reflects on how the reinterpretation of CITES "meant practically a third of my stock became unavailable overnight". 

One of the "Brexit benefits" often quoted was the possibility that more friction across the borders would encourage clients to buy British and boost British-grown plants. As tightening border controls cause unprecedented chaos at BCPs Imogen might be feeling a degree of relief that she took the decision to switch to British houseplant nurseries months ago.

"Cacti, carnivorous plants, the majority of orchids... it's almost impossible to import, which is obviously quite a large part of most houseplant departments.

"Luckily, I was already having looking into UK growers after Brexit - just in case anything got super difficult to import. And at the same time a lot of UK nurseries then opened up to garden centres - Oppenman's plants, Double H, Hills Brothers all opened up to garden centres about the same time.I was already ordering from them so I just got to order in much higher volume.

The only plants she's struggled with are more unusual orchids, she says, but initiatives such as Horti House which allows nurseries to trade as one unit is helping.

"You get some great nurseries in there like Dibley's who do Streptocarpus and Begonia.. and where before you would have to order either half a trolley or a whole trolley, you can now just order by the tray which means you can get a good range of more unusual things without having to kind of put all your eggs in one basket with a specific supplier."

She talks about the challenge of competing with supermarkets with their economies of scale, "but on the other hand, I think if you look at any supermarket at their house plant department, it is all half-dead... where garden centers and other plant shops really stand out is the level of knowledge and customer service they can offer".

At Thomson's she has added labels showing the air miles for plants on sale: "I'd like to introduce UK suppliers and just extend that so you can say this orchid or Monstera or whatever has come from 40 miles away and it's come from this nursery and it's a family -run business. I think it just adds to the value of the plant to be able to give it that origin."

It surprises her that, given the huge rise in popularity of houseplants in recent years, many garden centres fail to put on a good display.

New trends she is seeing include Marimo moss balls. They grow like a couple of millimetres a year. But for some reason they were flying off the shelves." The appeal for many customers she says, are plants that "thrive off neglect".

On peat-free, Imogen says customers are asking for it and garden centres are moving in that direction, ban or no ban. "Horti House is peat-free and again out of necessity I guess the other ones will come into line" she says.

On peat-free composts, she says: "I've noticed more and more people are mixing their own soils. So instead of just getting a packet off the shelf, they're buying a base and then they're buying perlite or coir or coco husk and then blending it for the specific plant".

And will the houseplant boom continue?

"I'm not sure we'll quite get the sky high sales we had during the lockdowns...They've plateaued since, but the interest is consistent. I don't think house plants will go away."

This week's guests are James Cairncross and Angela Lewis from the Midlands Parks Forum which has its annual conference on the 17th of October at the National Memorial Arboretum in Staffordshire. Highlights include keynote speaker Dr. William Bird, a GP who contributed to a select committee report on access to green space who will speak on health benefits of physical activity and green spaces.

"Other speakers include people from MHCLG, the Ministry of Housing, Communities and Local Government, Heritage Lottery Fund, and also some experience from out in the real world, such as Islington Borough Council" Angela explains and she outlines workshops also to be run at the event.

James addresses the "perennial problem" of parks budget cuts. "Despite there being quite a clear return on any investment in parks, local authority officers are still struggling to protect what they've got, let alone improve the funding for green spaces.

"Our chair of trustees Liz Stuffins attended the previous Government's DEFRA inquiry into urban parks, and they found that both the quality and the quantity of urban parks are in quite serious decline.

This exacerbates the skills shortages suffered by the parks sector but The Midlands Park Forum aims to help overcome this by offering learning events, the conference and webinars "focused on the skills and competencies in a framework that aligns with the Landscape Institute's framework on competencies identifying over 60 skills in six categories, which we've identified as being important for a good park manager. And it's not just about cutting grass. This is people skills, environmental stewardship, income and finance, future visioning and planning, and all the competencies that go with being a professional."

The lack and loss of expertise in the sector combined with budget cuts means some parks "are already losing their green flag awards because the authorities can just no longer attain the quality that's needed to keep those award...some councils now can't even afford the cost of the application, let alone the quality".

With a new Government installed, James acknowledges parks will have to "join the queue" when asking for more state funding but top of his list of asks is "a national urban parks strategy and it needs to be integrated into public health because the benefits of that are both obvious." Close behind is a wish that the Green Jobs Task Force be expanded to include the green spaces sector.

They discuss best practice in the sector and for Angela it means "local spaces that can become the hub of the local community and making sure that people do look at different collaborations locally, whether that's with local charities providing physical activity and exercise or local charities that provide volunteers to look after the green spaces and just making sure that all those things are considered in terms of local people having that space that they've got within 15 minutes of home".

For the future, the Forum wants to "continue to deliver quality service to members" including CPD offerings, via learning events and knowledge sharing.

Both our guests on the HortWeek Podcast broadly agree with the reasons for a peat ban and agree there is a need to reduce carbon emissions to help fight climate change. But they are not equally convinced a peat ban is the way to do it.

In the 'for' corner is cosmos and hollyhocks national collection holder and lobbyist Jonathan Sheppard.

Sheppard says: "You only have to look at places like Hampton Court where they have the peat-free garden where the plant list was massive. I've never seen a plant list as long which showed people that you can grow without peat. So I'm just wholly not convinced that you can't be a successful grower. But then I guess it depends on what do we mean by a successful grower. I just don't want to see rewards being given when there's an RHS sustainability strategy when using peat...It must be the wrong thing to do, given the science that we know about how much CO2 digging this cheap product up emits."

And in the 'not so sure' corner we have dahlia and sweet pea grower Darren Everest.

Darren argues: "Just for example in the National Dahlia Society, you try finding me one of the top elite growersn that don't use peat and I think you'll struggle to find any...growing flowers to national level requires a lot of time and years of knowledge and experience growing and I haven't found anybody online yet, certainly in the dahlia world, that has found a suitable non-peat-based product. "

HortWeek editor Matthew Appleby hosts the discussion which focuses on efforts to end peat use by growers and RHS exhibitors.

The pair reflect on their experience of using peat free and debate how significant the carbon emissions cuts achieved by ending peat use in horticulture will be.

The RHS plans to end peat use from 2026 and they ponder how this ban will affect different growers, awards, whether shows will attract fewer exhibitors and crucially, how it can be policed.

GroundsFest 2024 took place10 - 11 September at Stoneleigh Park, Warwickshire. Initial visitor numbers from day 1 (unaudited) of 4,738 were 40% up on last year, the show’s inaugural year.

The podcast was recorded on day 2 of GroundsFest amongst the hustle and bustle of the show. HortWeek senior reporter Rachael Forsyth spoke with Chris Bassett, event director at GroundsFest, Jonathan Snowball head of professional at Husqvarna and David Fisher head of landscape and rural at LANTRA about how the show has been going so far.

Snowball explained that Husqvarna took advantage of the outdoor space making its entire stand a live demo area – one section for chainsaws and another for robotic lawn mowers and ride on machines. Bassett explained that this was a USP when setting up GroundsFest, allowing exhibitors to have that flexibility with their space and offering something different for visitors. 

Fisher said conversations at the show centred around the skills shortage with LANTRA facilitating a “well attended” seminar on the challenges and opportunities in the amenity sector. Questions arose around where the next generation is coming from, keeping people in the industry, and how we can best show off what careers and pathways look like. 

Bassett said the show has had really good feedback so far, and while you will never get 100% positive feedback the team is ready to make tweaks based on feedback for next year. Overall, though, Bassett said visitors are enjoying being able to get their hands on the kit and test it.

Alan Down is a gardening broadcaster and writer and current HTA president, shortly to be replaced by Will Armitage after two eventful years.

He studied at Cannington and Pershore College of Horticulture and after a spell working Germany, he developed and managed Hillier Nurseries' container grown and seed propagation nurseries for nine years.

For the following 35 years, Alan built up Cleeve Nursery and Garden Centre, near Bristol and alongside hi wife Felicity, co-presented the long-standing ‘Garden Calendar’ TV programme.

On the podcast Alan talks about his role at the HTA including presiding over changes in structure and strategy.

He discusses his desire to shift the terminology and emphasis of production horticulture from 'ornamental' to 'environmental' horticulture which runs alongside the topics the HTA engages with, including with the Government. These topics include the issues of trade and border checks, "the extra costs [growers] incur... and we continue to apply pressure to try and resolve the issues that are there. We also have huge concern about the few inspections that there are, which means that we are a threat in terms of importing pests and diseases which could be harmful to our industry and indeed to the country as a whole".

He discusses the on-going shift away from peat. In the absence of official figures (since 2022) he estimates garden centre use of peat-based growing media is down to around 10%, but the picture with growers is more complex.

"Some have been growing peat-free for quite some time. Others are still trialling and finding out what medium works for them and how to handle growing plants in peat -free compost and others may not have even started. But we are there to support our members in this transition and we'll continue to do that."

He and HortWeek editor Matt Appleby discuss the Lords Parliamentary horticultural inquiry of 2023 and the impact, if any, it has had since on the sector, which has partly been disrupted by the arrival of a new Government, Alan points out.

But. Alan says, he believes the HTA is well-placed to influence the new administration as an institution which represents growers, landscapers and retailers. He talks about initiatives such as inviting MPs to visit growers on site and the opportunity exhibiting at Chelsea gives the HTA to meet them in a "in a more relaxed mood'.

Matt and Alan talk about the health of horticulture shows including collaborations with GIMA, Alan's enthusiasm for more regional events and the HTA's own conference taking place on September 25 at the International Conference Centre in Birmingham.

And as he celebrates his 50th wedding anniversary, he contemplates life after the HTA and what it might hold as well as his latest Desert Island plant.

A Sussex native, Susan Raikes, the new director of Wakehurst, Kew's wild botanic garden in West Sussex (she joined in June) was familier with the garden since childhood. 

"We're Kew's younger, bigger and wilder sister and very much a botanic garden with a purpose...a site of horticultural and scientific excellence and a living laboratory where groundbreaking science projects are taking place as well. So lots of beautiful gardens, beautiful spots to come and visit, but some really important science and horticultural work going on as well."

After Kew released a report detailing risks to over half of its 11,000 trees, Wakehurst will carry out a similar exercise next year: "it's a different challenge, but absolutely we're thinking about the resilience of the planting".

She talks about the effects of climate change on the garden, with respect not just to plants, but impacts for visitors and scientists working at the centre.

Related to this, Wakehurst has been "championing meadows" via it's Meadowland feature this summer (until September 10) and has a focus on threatened and rare UK habitats which have been combined with newly commissioned pieces of contemporary art to enhance the ecological and educational aspects.

Wakehurst is home to Kew's Millennium Seed Bank, which houses more than 2.4 billion seeds from around the world and which will celebrate its 25th birthday next year.

Among research programs currently live at the garden Sue highlights Nature Unlocked, "which is helping us to use Wakehurst as a living laboratory, looking at it as an ecosystem observatory. We're looking at pollinators and carbon, but also well-being and the different kinds of landscapes and environments that people get the most benefit from". 

The research project will be reflected in features in visitor areas such as the children's garden which will house a bee bank, a rebuilt mud kitchen and edible meadow.

Next year will also see the 60th anniversary of Kew's presence at Wakehurst and the garden plans to bring "to life that story of being a living laboratory so that visitors really know that they are visiting somewhere that is really making a difference in terms of all of the work we need to do around climate change and habitat loss as well."

Previously Sue was director of learning at the Science Museum Group and before that you were head of learning and national partnerships at the British Museum and is familiar with "taking sometimes quite complicated and specialist content and then working with that in a variety of different ways to bring it to as many people as possible" and she plans to bring these skills to bear at Wakehurst.

Wakehurst has enlisted two champions, TV GP Dr. Amir Khan and BBC Springwatch presenter Megan McCubbin to help "amplify our message and spread the word about this incredible wild botanic garden that we have." Local resident and A-list actor Cate Blanchett has made a promotional video for the garden and it is hoped she will have more involvement in the future.

The aim is to build on the 400,000 visitors Wakehurst receives every year and hopes to "reach people who might not know about us" through access schemes and community work.

GroundsFest 2024 takes place on the 10 and the 11 of September at Stoneleigh Park, in Warwickshire. The free annual event is a must-attend for grounds staff, greenkeepers, landscapers, designers & architects, gardeners, local authorities, estate managers and contractors.

It combines indoor business and education opportunities with outdoor demonstrations and on the evening of the 10 September there is a live music festival for visitors to network and unwind. 

HortWeek senior reporter Rachael Forsyth speaks with Chris Bassett, event director at GroundsFest about what to expect from this year's show, as well as exhibitors Wayne Grills chief executive at BALI, and Ian Graham chairman of Amenity Forum about the benefits of attending and exhibiting. 

2023 was the show’s inaugural year, but its success has meant additional space has been added both indoor and outdoors. Bassett explains that the success also accelerated the goal of reinvesting profits from GroundsFest back into the industry to support education through the GroundsFest Education Fund.

Grills explains that he attended as a seminal panellist and visitor last year which encouraged him to have a BALI presence at the event this year, with the association hosting its AGM at the show. Graham describes why Complete Weed Control was drawn back to the world of exhibitions through GroundsFest, as well as what visitors can expect from Amenity Forum at the event.
