ZOOM Meeting 1st December

Our speaker was the return of Geoff Hodge an author of 8 gardening books including 5

for the RHS. His talk was entitled ‘Winter in the garden – beating the winter blues’ very apt for this time of year!

Planning is of paramount importance for maximising winter colour in the garden.

Think before you buy.

Start with structural plants to give a focal point, perhaps a tree, large shrub or a pergola.with a climber. Interspersed with smaller shrubs and surround with plants that give good ground cover. Brown is not a good garden colour!

Looking out onto a colourful winter garden can help lift depression during the winter months and gives a feeling of well being.

Garden designers tend to plant one evergreen plant to two deciduous plants.

Conifers give shape and structure and colour with green, yellow and blue varieties. Heathers provide many colours but always trim after flowering to keep compact.

It seems we in the UK love variegated leaves more than any other country in the world!

Some of Geoff’s favourite winter plants include Leucothoe Scarletta a branch of the rhodedendron family with green and red leaves. Pieris ‘flaming silver’, evergreen prefers acid soil and a shady position. Carex siderosticha has variegated leaves and is related to the grass family. Many types of euphorbia with yellow flowers and ‘hairy’ leaves which mean it is drought resistant. Lamium maculatum with white flowers that gives good ground cover. Ornamental cabbages in white yellow and purple make an unusual combination but beware they are paticularly enjoyed by rabbits!

Winter flowers include Daphne mezereum flowers in January to March and thrives in deep shade. Strong scented, slow growing Hamamekis Mollis is fiery in autumn with yellow flowers.

Mahonia an architectural plant with strong scent and yellow flowers. Viburnham bodnantense with flowers on bare stems and strong scent. Annual pruning is essential as it can grow up to 10ft !

Helleborus foetidus known as the stinking one and helleborus niger known as the potters wheel with its big white flowers. Also known as the Christmas rose as it does not flower at Christmas!

Bulbs include Cyclamen coum a hardy ground cover which can multiply when ants who are attracted to its seeds make off with them and can deposit them in other parts of the garden! Galanthus Dionysius are only favoured by keen collectors as each bulb can cost around £5.00

Berries add colour. Cotoneaster horizontalis with its variegated leaves can even grow up walls. Sometimes known as the council plant as it can grow anywhere.

Ilex or holly need male and female plants to provide a prolific crop of berries. Pyracantha ‘Navaho’ a good hedging plant with white flowers in summer and berries in winter (if the birds don’t eat them first!

Winter stems provide colour in winter. Silver birches with their silver and white branches can be spectacular in the dark days of winter. Rubus thibetanus has white stems but needs regular attention as it is a garden thug and can take over a border if not kept in check.

Leave aliums alone for their large seed heads create structure and are an ideal hibernating place for ladybirds.

Garden centres now stock many brightly coloured glazed pots for patio plants which complement winter planting of pansies and violas.

The Harpenden Gardening Society will publish it 2021 programme of meetings and events in early January.

ZOOM Meeting 10 November 2020

‘Taking a Garden to Chelsea….Beneath a Mexican Sky’

We were delighted our guest speaker Manoj Malde was able to ‘ZOOM’ his presentation to around 50 members on Tuesday this week.

Manoj started his talk explaining how his ancestry is Indian. He was born in Kenya and started his career in Fashion Design. Being a fashion designer for 18 years before wanting a career change and has now become a garden designer for over 9 years.

Many elements of his past career have been very obvious in his garden designing. The knowledge of colour and display, layout, balance and placement move easily into the planning of a garden design.

He then moved on to decribe how a garden designer takes a design idea to Chelsea Flower Show and all the hoops one has to jump through in order to even be excepted to get as far as having a show garden at Chelsea, the ultimate accolade.

Applications have to be submitted to the judging panel the previous year, so a lot of planning, ideas of a theme,what plant to use etc has to be formally submitted by July the year before you wish to show. Around July or August the submissions are judged to see if they will be going forward to a second judging. If you are shortlisted, you are given feedback and a list of any changes that would need to be implemented before a final judging is done in October when you are advised if your design has been selected.

Manoj showed us copies of detailed drawings and layouts, planting schemes and the various trial colour schemes for the backgrounds and groundwork he went through to get ‘just the look he was aiming for’

He also explained that he travelled to Europe to obtain some of the more unusual plants that he needed for his design but that in planning for Chelsea you need to have back up to your planting selection as plants do not always ‘behave’ for you so alternatives were bought too. He used a selection of plants that will be familiar to UK gardeners such as Salvias (Royal Bumblebee-red salvia) which are hardy and have a long flowering period and California poppies.

Most plants were inspired by Mexico and the Mediterranean such as Agarve Americana, Agora, Astepia, Dracena Dracco-Dragon tree. Bescanaria’s, Cacti (Stenocereus Marginatus) tall flowering Erieron, Kavinskianus (fleabane) Echeveria, Puya coerulea.

The Arbutus Unedo (strawberry tree) Manoj was very proud of as he was told by many nureries he contatcted that he would not be able to find a multi stemmed tree, only shrubs! Manoj went to Italy and found exactly what he was looking for in a deserted area in the nursery there, heavily laden with fruit and shipped to the UK in February, so it had a chance to be nurtured in the UK climate. It became a main feature of the garden.

Manoj explained that he liked and was inspired by the work of Luis Barragan , a Mexican architect and engineer born in 1902. Barragan’s signature colour washed walls in clementine, coral and cappuccino provide dramatic back drops to the planting scheme. Zinc micro-cement steps floating across a large aquamarine pool often seen in Barragan’s work.

His obsession with horses is represented through copper wire sculpture by Rupert Till and Manoj wanted the spirit of the horse to be in his garden, along with Barragan’s love of water represented by the blue pool he had within the 10 metre by 6 metre by 6 metre space he had to work with at Chelsea.

A generous courtyard is turned into a modern, luxurious outdoor space with clean linear lines. The garden appliead a new thought process, using tolerant plants that merge Mediterranean style with country cottage planting.

The garden is designed around two natural, mature multi-stem trees that provide structure in the garden. Agaves provide rhythm and softer drought tolerant herbaceous planting breathes beauty into the garden. Simple lighting created bold shadows on the walls.

Beneath a Mexican Sky gave the opportunity to bring together two subjects that resonate with Manoj….colour and Mediterranean planting

Manoj was delighted that his first ever Chelsea garden obtained a SILVER GILT medal.

A great achievement.

ZOOM Talk 13 October 2020

Matthew Biggs ‘Dig for victory, was it successful?’

Our second Zoom evening was an informative look back to the second world war and how through hardship and necessity the people of Britain coped to feed themselves during the six years of devastation from 1939 to 1945.

The phrase ‘Dig for victory’ first appeared in the London Evening Standard in September 1939 and was coined by a young left of centre journalist by the name of Michael Foot who later became the leader of the Labour Party!

The German onslaught deliberately caused enormous damage to target Britain’s food supplies as so much of our basic supplies of fruit and vegetables were imported from overseas.

For example 287,000 tons of bananas were imported in 1939 but by 1942 there were none due to the success of German operations sinking merchant ship tonnage.

Huge shortages of supplies led to severe rationing and the Government had to quickly organise a massive propaganda exercise to encourage the British population to grow as much food as possible. It sought the help of the RHS and Allotment societies to help produce and publish countless booklets and leaflets to educate and inform people. Not easy given the shortage of seeds and during the War no weather forecasts were published.

Matthew showed us an amazing number of these items from his personal archive and his extensive research including a best seller ‘Cloches Versus Hitler’ written by Charles Wyse-Gardner….possibly not his real name!

Old photographs of allotments created on tube station platforms, a circular allotment dug into a circular bomb crater, a large vegetable garden in the moat of the Tower of London to list just a few!

Sales of spades and wheelbarrows took off in the early years.

To help nurture the planting when manure was scarce, additives including soot (plentiful in coal burning days) wood ash, guano and raw sewage were recommended. It was said many allotments in and around London had a particularly pungent air!

The Germans even went to great lengths to wreck the efforts of growers and destroy crops by the Luftwaffe dropping cardboard boxes of pests on allotments in Kent.

Was it all worth it? The answer has to be Yes, thanks to the great ingenuity and hard work by so many to feed the nation during the darkest days of the second world war.

The next ZOOM evening will take place on Tuesday 10 November at 8.00pm with Matthew Malde the medal winning garden designer who will talk about ‘A designer journey to Chelsea’ It will follow the AGM at 7.45pm.

Talk: 8 September Janet Buist via ZOOM

Due to the current restrictions for large gatherings our first Talk in the Autumn season by our guest speakerJanet Buist, a retired nursery owner ,was via ZOOM. Over 40 members tuned in to  hear Janet share her keen interest and extensive knowledge on the ‘wonderful world of salvias’

Amazingly in 1975 there were only 8 known species of salvias. Today there are over 1,300 species!

Pioneering work by Pat Vlasto in Dorset and Christine Yeo (who has published two informative books) and others increased the range and popularity of species spectacularly in the last few decades. The National Collection of salvias is now held at the Kingston Maurwad Gardens near Dorchester.

William Dyson of the Great Comp Gardens in Kent  (Society members visited a couple of years ago) also has an extensive collection of salvias

The foremost website for salvias can be found at robinssalvias.com

Why have salvias become so popular? Flower power! Range of colours: Blues, reds,yellows, soft apricot and even black! Fragrant leaves.Attractive for bees, some steal the nectar!

Janet explained she lists them into five groups:

Hardy herbaceous: Can withstand winters. Plant in spring in well drained soil and cut back in winter.

Hardy evergreen: Mostly come from the Mediterranean. The leaves of salvia fruticosa can be infused in hot water and drunk as a refreshing tea. Plant in spring and ideally in full sun.

Half hardy: Salvia Patens with large gentian blue flowers and Salvia Cambridge Blue varieties can be treated like dahlias. Cut down in winter and mulch and cover with a cloche to keep roots dry.

Tender evergreen: Mostly derive from the new world. Salvia confertiflora with pink flowers and Salvia oxyphora (discovered in Bolivia) with coral red flame petals are particular favourites. Need to be sheltered from wind and need a frost free home over winter.

Shrubby: Most popular of all, for their long flowering. Varieties include Red Velvet, Cream, Icing Sugar, Orange Door, Cherry Lips, So Cool Pale Blue to name but a few. Plant out in May in well drained soil, sunny or sheltered position. Pruning in late July (the Hampton hack!) will ensure continuous flowering.

Salvias need protection from several pests and diseases. Notably whitefly and the capsid bug. Botrytis in over wintering plants in the green house can happen so it is best to maintain good greenhouse hygiene and allow fresh air to circulate.

Our next Talk is scheduled for 13 October when our guest speaker will be Bryan Hewitt the Head Gardener at Myddleton House.

Meeting Tuesday 11 February 2020

Despite high winds and an icy February chill, a full house attended the first meeting of the year. The speaker was Dr Ian Bedford an entomologist whose talk was ‘All you’ll ever need to know about slugs!’

What an  absolutely, interesting, fascinating and amusing talk, accompanied by a superb colour slide and video presentation, it was.

Surprisingly not all slugs devour your garden plants!

Slugs are hermaphrodites and evolved from snails around 500 million years ago. There are 5000 species worldwide and are essential for the ecosystem. 40 species are established in Britain. Slugs have brains and tentacles and can regenerate if cut. They thrive in damp conditions, producing slime which aids movement, offers a defence against predators and attracts mates. They will lay 2000 eggs in a lifetime. Mainly nocturnal, they feed on plants by rasping and ripping with their radula, a long tongue like proboscis.

Red and black slugs are good for gardens as they thrive under compost heaps.

Greyfield are surface slugs which can devour flowers and vegetables.

Yellow slugs eat mould, moss, lichen and are partial to pet food!

The most invasive slugs which can grow up to 6 inches long do most damage are the Spanish slugs. They are particularly attracted to yellow flowers especially fields of rape seed. They also eat other snails and dead mice. Fortunately they cannot cope with winter and die.

There are three ways to try and reduce the slug population in gardens.

Naturally. Frogs, toads, centipedes, snakes, toads and nematodes, hedgehogs all enjoy a good meal of slugs!

Physically Barriers of egg shells, copper, seaweed, salt, beer traps.

Chemically Do not use Metaldehyde as this will kill other wildlife especially hedgehogs. Ferric Phosphate is recommended as this is not harmful to other wildlife.

Drowning slugs should be done in a bucket of soapy water as this will restrict their escape. Bleach must be used afterwards to kill off any parasites which the slugs will have consumed. Again any slug remains must not be left on open ground as any household pets could be infected by the parasites.

For those interested, The RHS are recruiting slug spotters across Britain to take part in the largest garden study in 70 years. The RHS is calling on people to assist in a PHD study aimed at identifying species currently active in Britain, their abundance and what attracts them into gardens. The survey can found at rhs.org.uk/slugsurvey

The next meeting will be on Tuesday 10 March at 8.00pm when our guest speaker will be David Coop of Elsoms Seeds who will talk about ‘How to choose the right compost’

Meeting 3 December

For our last meeting of 2019, the Society welcomed Chris Bryant the Retail Manager of Ayletts Nursery to talk about some of the most popular selling plants during the pre Christmas period. His talk included some useful tips on ensuring plants thrive indoors during the winter season.

Some top sellers include Japanese and Indian varieties of azaleas . The Indian varieties are not hardy. Azaleas need constant watering. Ideally rainwater. Fast growing in a warmer atmosphere.

Ayletts grow over 4,500 Poinsettias each year for Christmas purchases. It is important for the plants to be wrapped before leaving the shop (Ayletts do this but not in many other outlets) as they will not fare well in a sudden drop in temperature. Indoors must not be placed near radiators and no drafts.

Peace Lillies can be grown successfully in darker areas and can clean the air, Particularly good for an office environment.

Indoor Jasmine is very popular with their fragrancy and masses of white flowers. Can be cut back by a third in July to encourage more flowers.

Palms are easy to maintain and should be turned when watered. A short spray is ideal to stop the tips going brown.

African Violets can cope with neglect! Blue varieties are stronger than white or pink varieties. To propagate just cut the leaves and place in water and watch the roots grow. Easy!

Ayletts grow over 3,500 cyclamen each year. Need to be kept in a cool environment. Not so good in modern centrally heated modern houses. Water from underneath and take care the corms if too wet are subject to rotting.

Orchids have grown in popularity over the years as they are now grown in large numbers in the UK. Feed via the leaves. When flowering is finished the stems should be cut above a leaf node but not too far down the plant.

Christmas Cactus prefer a shady place and it is important not to change the position of the plant. They can be put outside when temperatures rise but again place in a shady place.

 

Lastly this year the amaryllis bulbs can now be bought with an amaryllis printed Christmas jumper….hurry while stocks last!

Ayletts have been in business for 66 years and for those that don’t know it the sat nav reference is AL2 1DH, Telephone 01727 822255. http://www.ayletttnurseries.co.uk

 

The next meeting of the Harpenden Gardening Society is on Tuesday 11 February when our guest speaker will be Dr Ian Bedford who will tell us everything we need to know about SLUGS !
