Visiting the 17th Southern Growers Exhibition at Roundstone Nurseries in Lagness, West Sussex, this month, those questions still bugged me, and not just for bedding.
Farmers are getting good TV airtime on Sunday evenings in BBC1's Countryfile, with Adam Henson visiting US dairy farms, John Craven picking apples in Herefordshire and Matt Baker picking pumpkins in East Anglia.
So where is the coverage of decorative horticulture? Why are hi-tech plant nurseries such as Roundstone not on Gardeners' World? If Henson can take his wool to Saville Row to get a suit made, why can't we see the nurserymen taking their produce to the garden centre golden mile at Crews Hill, north London, or to city parks?
At Southern Growers I heard from Agralan that next year we will be able to buy hives of our native bumblebee, Bombus terrestris audax, to use in gardens and orchards. Their life cycle is similar to that of wasps and the broods can be left to naturalise after use to increase the indigenous population of bumblebees.
I saw Distribug machines for accurate distribution of biological control parasites (Koppert), demonstrating the ingenuity being introduced for chemical-free pest control in commercial crops. The associated visits to Hill's poinsettia and orchid crops were spectacular, providing useful pot plant care tips for consumers.
What about the British-bred tomato 'Terenzo' and 'Lizzano' from Simon Crawford and John Burrows getting all-American selection awards and their 'Lozetto' showing blight tolerance? Surely these things are of interest to both gardeners and the general public?
At Chichester I heard about cucumbers that produce heart-shaped slices, saw the new pink SunPatiens and got news of the butter-yellow Bacopa. There is no shortage of new things, but whose job is it to tell the world about them?
