In January, I spent hours trolling through seed catalogues, drawing up a list of things to grow and getting completely carried away. The list was miles too long – no way did I have the space to grow them all, but everything always looks so irresistible. The seeds arrived almost immediately, followed by a few plants. There’s sometimes such a lag between ordering and delivery of some items that I almost forget I’ve got them to look forward to. Then last weekend, I received my hippeastrum Sonatini ‘Veneto’ bulbs that will flower outside this summer. They’re quite a breakthrough, as they’re hardy and can be left in the ground. I wonder if there’s anything else to come that I’ve forgotten about!

Local shows have a future if garden groups are adaptable Alamy
Show debate identifies ways forward
Adaptability and use of social media are key
E
ncouraging and actively supporting younger people and vastly improving communication, particularly the use of social media, were measures that could effectively help revitalise local flower shows, a recent debate identified. Over 120 people attended The Flower Show Forum, organised by garden-centre chain The Gardens Group (TGG) in Dorset, to hear representatives from garden clubs, plant groups and the RHS discuss reasons why local flower shows were experiencing problems. RHS Affiliated Societies co-
ordinator Susie Corr summed up the mood, “Although there was genuine passion for horticulture and engaging with local communities, some clubs reported their show events were experiencing decline,” she said to Garden News. “However, the successful ones had adapted to new circumstances, tuning into the needs of their communities, putting on new events and classes, and actively showing people how to ‘show’. We’ve found in recent years urban garden groups have increased membership, while those in the country are static or had fallen.”
Children will engage if opportunities are exciting
Other points raised included the need for clubs to warmly welcome new, younger members or first-time gardeners, listen to their ideas and actively encourage their involvement in shows, perhaps using incentives such as raffle tickets or free refreshments. Improving communication on all fronts was key and social media was essential, particularly if young people were to be inspired. Fostering interest in growing plants for shows in local schools was seen as important for the future. “However, children need the right type of encouragement and any
efforts need to be tuned into the school year. It’s no good holding a show when children are on holiday. Children also need to have the right role models to engage with,” said Susie. Use of the RHS’ latest edition of The Horticultural Show Handbook was also seen as important in guiding a broader appreciation of running shows and identifying methods of exhibiting and judging. A second Flower Show Forum is scheduled for Thursday September 15 at Castle Gardens garden centre, Sherborne, Dorset, where participants to the first will be invited back to share experiences and how they implemented new ideas. l To attend, call 01935 814633 or email castle@ thegardens group.co.uk l Discussions from The Flower Show Forum debate will continue online at www. thegardeneronline.co.uk/forum RHS
Updated book is vital aid The Horticultural Show Handbook was cited as an essential guide for both show organisers and exhibitors staging competitive classes at local events. Published by the RHS, the revised 8th edition has been rewri en and reorganised to make it more user-friendly and relevant to amateur shows. Revisions were based on advice from many national plant societies, with the sections on blueberries, bonsai, gladioli and orchids being rewri en. Criteria for judging Chinese artichokes, coloured cauliflowers, minicucumbers and tomatoes in a truss, among others, have been introduced. l Priced £8, the handbook is available from RHS bookshops or via mail order by contacting 01483 211320 or visiting www.rhsshop.co.uk

Pot up Shasta daisy plugs
N
othing sums up summer like a bed of daisies bobbing in the breeze. Shasta daisies, or Leucanthemum superbum, will flower for months on end. In fact, with regular deadheading, they can be in bloom from June until September – a good-value plant. Shasta daisies are clump-forming perennials and make the perfect partners to all your other summer plants, particularly when teamed with hot border favourites such as heleniums and crocosmia. They’re superb as cut flowers, too, and bees and other pollinators love them. They’re really easy to grow – stems can be left in place over winter, but they can be rather tatty, so you might want to cut them down in autumn after flowering, and then divide congested clumps in spring.

Rotate windowsill seedlings
Windowsills are sometimes tricky to produce good seedlings from, as the light source is usually limited to one side. This is why it’s necessary to rotate them every few days, otherwise they will become weak and leggy from lack of sunshine. You could also use a homemade foil-covered cardboard reflector to direct the sun back at your needy plants. For best results, though, grow in a conservatory or greenhouse, where plants will grow sturdier and straighter.

6 ways to stave off slugs!

Nematodes – naturally occurring microscopic worms can be applied to soil and pots via a watering can. They kill the slug from the inside.
Copper tape – copper is said to repel slugs and snails from walking over it. Stick it discreetly around your pots for good measure.

Stop slugs! How to prevent an infestation
W
we’ve been having, slugs are in their element – plus it’s spring, meaning they are currently laying eggs, producing another generation of pests for us to deal with. Should you have an infestation and simply too many for your garden animals to eat, there are lots of ways you can try to keep populations down. The RHS gardening advice service always say that slugs and snails top the list of phone calls every year with enquiries on how to deter them, so they’re clearly the bane of many gardeners’ lives. Take a look above right for some of the ways you can try to be rid. Good luck!

Upturned grapefruit – slugs are drawn to grapefruit. Hollow one out and they should collect under it for you to dispose of.

Beer trap – sink a vessel of beer into your soil, and slugs will be a racted to the yeast in it. They’ll climb in for a sniff and drown.
Slug pellets – unless organic, these should be a last resort, as they can be a danger to wildlife. Slugs will digest them and get poisoned.
Look out for Spanish slugs! First reported in January 2013, there has been a new slug in town over the past couple of years, threatening to take over our native species – the Spanish slug, or Arion vulgaris. Last year was a record year for slugs, which unfortunately paved the way for these Iberian monsters to take precedence. They can reproduce twice the offspring of British slugs, and are sadly not as susceptible to deterrent products. But they do eat our native species –
that has to be a bonus! Spanish slugs are very large and can grow up to 15cm (6in) long, and they are light brown in colour. Be vigilant – pick them off, collect, and carefully dispose of them.

e have slugs for a reason in the garden – they are valuable members of the ecosystem, though it might not seem so most of the time! They are around to help with our gardens’ decomposing process and munch away on dead matter to break it down, but they like to get carried away at times and have a go on what often seems like all of our precious plants. They are also a great benefit to garden animals as an excellent snack for hedgehogs, toads, garden birds and chickens. Due to the wet weather

Egg shells – Slugs like soft surfaces to walk over, meaning a crumbly layer of egg shells can deter them. Apply liberally to soil surface.
