Meeting October 11

Talk: Michael Brown Garden Historian & Author

Again a good attendance of around 50 members and guests were present for an interesting talk and slide presentation entitled ‘Knots & Bowers, the Tudor Garden’.

Gardening has been essential for many people throughout history. Only the very wealthy could afford gardens for pleasure alone. Most gardens combined beauty with practical use. Food flavourings, medicines, textiles and dyes could be grown or found growing wild locally.

Michael’s colourful slideshow took us through a series of English decorative and medieval gardens throughout the centuries.

The first gardening book to be published in English was in 1594 by Adam Islip. Parterres were around before the Norman invasion and it is thought the design of knot gardens were copied from the embroidery on ladies dresses.

Borders were made up of thyme, lavender and hyssop. Box was not used until the 1600’s.

Garden fountains were introduced by the Romans whose use of channeling water in settlements is well known. A early fountain was installed in Kenilworth Castle to entertain Elizabeth 1st.

Ponds built waist deep were popular in Tudor Gardens for guests to admire the fish before they were eaten! No vegetation was grown around ponds as is common today.

The next meeting of the Society will take place on Tuesday November 8 and will feature David Coop of seed specialists Elsoms who will talk about “Breeding Better Plants’ .

His talk will be preceded at 7.45pm by the Annual General Meeting

Meeting September 13

Our first meeting of the autumn was well attended on a rainy evening at Roundwood Park School. Our guest speaker was Chris Thorn of Ayletts Nurseries in St Albans.

His subject was ‘Towards sustainable gardens’.

Chris opened his talk with an invitation to see their new Celebration Garden showcasing 60 years in business. The nursery originally grew dahlias and over the years Ayletts have won 39 RHS gold medals (36 in consecutive years) for their dahlias.

Chris reminded us that compost containing peat is to be banned from 2024.

Ayletts stock a huge range of composts and the peat free composts are coming down in price as more and more gardeners are changing to peat free varieties.

Newer and more environmentally friendly slug and snail pellets are now available. Slugs injest these new pellets which give them indigestion causing the slugs to bury deep into the soil to die, thus leaving the soil surface free from contamination.

Given climate change it is even more important to conserve rainwater. New ground watering systems can be connected to water butts to deliver a drip by drip to borders and beds. On the market currently is a system made entirely of car tyres!

Interestingly we were told when disposing of black plastic plant pots and seed trays there is no point in putting them in your council recycling bins as the machines at the recycling centres cannot ‘see’ black plastic so they are diverted to landfill. Ayletts now sell blue plastic pots which can be recycled. Ayletts offer to take your old black plastic pots and can recycle them in Germany who have the machinery to convert them into coat hangers!

Next time you buy clothing in M&S it might be your old plant pots coming home to you!

Ayletts are constantly investing in new products and ideas and ways to help customers to become more sustainable gardeners.

Those with all electric cars can now take advantage of 6 newly installed charging points in the car park.

Meeting May 10

Marina North of Plantiful Terrariums

‘Garden in a Bottle’

Our speaker this evening gave an excellent presentation and demonstration of the wonders of indoor gardens not just in bottles (closed or open) but baubles, balls, geometric terrariums in all shapes and sizes. Carboys too!

Marina who emigrated from Sydney to London in 2016 shared her passion and knowledge of this intriguing genre.

The centrepiece of the presentation was a demonstration of how to create a garden in a bottle.

Starting with charcoal as the base followed by a layer of small gravel, then a layer of soil/compost. It is important to level each layer to maximise the effect.

She chose a selection of plants including an Asparagas fern for height and texture surrounded by carpet and cushion moss, an English ivy plus an air plant which is native to the tropical climate of South America.

To manipulate the plants in position she used a series of long tweezers and skewers to to place everything in the bottle. She then laid a series of larger pebbles and bark to create a natural look to the garden.

It is important to use filtrated or rain water rather than tap water which will contain chemicals which will be detrimental to some plants.

Watering can be done by spraying or using a pipette. A ‘fogged up terrarium is a healthy terrarium’

Terrariums should last for years with minimum maintenance. The first terrariums were created in 1842.

Positioning is important. Avoid placing them near radiators and not too close to a window which could be harmful on very sunny days as it will dry out the plants.

If this was Marina’s very first talk, we must congratulate her for an entertaining ind informative evening.

TALK April 12th 2022

Darren Lerigo, Owner of Modern Mint

‘Diluted:How to cope with excessive heat and lack of rain’

The first time our Speaker gave this talk was in Shropshire when the county was being deluged continuously with heavy downpours of rain. He had to make an early exit after his audience found it all very amusing!

Fortunately he didn’t have to make an early exit last night. On the contrary members had lots of questions for him following his intersting and entertaining talk.

Given climate changes we are experiencing, the next stage in garden evolution, the majority of garden designers will be developing and encouraging ‘Rain Gardens’ to combat expected future drier conditions. Principal idea is to CAPTURE/STORE/REDISTRIBUTE rainwater.

Darren gave us many examples how this can be achieved. Create a sunken border (Bio Retention Pot in modern day jargon!) to retain water for longer. Plants that enjoy bog like conditions include Persicaria (good for containing ground elder) Eupatorium (provide lots of nectar for bees), Aster, Verbena bonarriensis are also recommended.

  • Full list of suitable plants at the foot.

Permeable paving for patios will again help to retain water. Mulching with bark of compost is a must. Compost containing wool holds water and contains nitrogen Gardens need to slow down and store water. A green roof on a shed or an outbuilding is another good solution. Mixing copper in rainwater makes it cleaner. Grey water can help but leave it for a minimum of 3 days to dilute out soaps and shampoo.

On a show of hands members only used rainwater on their gardens as opposed to tap water which was the first time in Darren’s experience he had this result!

Sink terracotta pots into the ground to let water seep out over time. When plants are established they need little watering. Always water early in the mornings not in the evenings.

In Essex all new build housing developments must agree to incorporate ponds and swales (flat bottomed canals a sort of gutter) to retain rainwater.

When carrots are established they need little water as it will discourage carrot fly. Tomatoes when established should be watered infrequently as over watering will dilute the taste. If you want really hot chillies only water when the plant is stressed!

If you are fortunate to have a stream running through your property get a beaver who will quickly build barriers to slow down the flow of water!

ZOOM Meeting 8 February 2022

Lesley Chamberlain of LC Plants gave a talk about the ‘Life and Gardens of Gertrude Jekyll’

It was an interesting start with brief summaries of the family background. Would you believe that just a few centuries ago, in 1738, a relative of Gertrude’s, Sir Joseph Jekyll, left money in his will to reduce the national debt ? It was then onwards to look at the early influences in Gertude’s life that may have sparked her interest in gardens. The surroundings of Bramley House in Surrey, beacame a wonderful world for her to play in with her six brothers. All that play with boys and no female peers made Gertrude a bit of a tomboy, which definitely helped her stand her ground in her later years as a garden designer.

When she turned 18, Gertrude then became one of the first women to study at South Kensington School of Art. It was there where she studied not only art but also botany, anatomy and the science of colours. Gertrude also enjoyed her time with her father, looking at his scientific approach to things.

Later influenced by the likes of John Ruskin and William Morris, Gertrude started designing gardens in an Arts and Crafts style. Her close friend Edwin Lutyens often designed the houses that Gertrude would design for. This created a wonderful partnership of fluid house and gardens, with a close friendship that never bothered Edwin’s wife as Gertrude was considered one of the family.

Lesley has been lucky enough to visit some of the gardens Gertrude drew up. She showed us photographs of marvellous planting techniques and interesting dry stone pillars and paving, Some of the gardens are:

Hestercombe

The Salutation

Vann

Lindisfarne

King Edward V11 Sanatorium

Tylney Hall

Upton Grey

Munstead Wood (Gertrude’s own home, now privately owned but you may be able to visit if you write to the head gardener)

In her later years, Gertrude unfortunately had deteriorating eyesight, which made her stop certain hobbies, but she carried on designing gardens. Never married, Gertrude died in 1932 without any children but with many dear friends. Edwin Lutyens simply describer her gravestone with :

Artist Gardener Craftswoman

One more thing: when you look for pictures of this incredible woman, you’ll never see her without a hat on!

Meeting September 14

Speaker Jacqueline Aviolet

“Hardy Geraniums-history and propagation

At our first ‘live’ meeting after 18 months of Zoom talks we were pleased to welcome 46 members and guests who enjoyed an informative and humourous evening talk.

Hardy geraniums are mostly pink, blue, mauve and white colours. They can grow in sun and semi shade with ease. You do not have to bring them in, in winter, some will die down into the ground and some will have leaves showing all through the cold winter months. Geraniums greatly support the insect world and different varieties will re-grow from spring to autumn. They grow in any type of soil in sun or semi-shade and bugs and snails do not feast on them. What’s not to like!

At the nursery in Kent over 400 varieties are in stock. The nursery is not open to the general public and all plants can be purchased via mail order via the website. All plants are grown in the open with no poly tunnels.

Members were shown various simple techniques for collecting seeds and taking cuttings. Important to always plant cuttings around the edge of the pot to maximise saturation.

A few of the many varieties in stock were featured in the talk.

Geranium ‘Anne Thomson’ rich magenta pink with black eye, flowering June/October, busy green foliage, height 45cms, sun/semi shade.

Geranium dalmaticum ‘Album’ shell pink, flowers May/June semi evergreen, height 10cm, sun/semi shade, low compact foliage, rock garden and pots.

Geranium himalayense ‘Baby Blue’ large blue/violet, flowers May/July, height 45 cm, sun/semi shade.

Geranium nodosum ‘Silverwood’ pure white flowers, thin acer shape fresh green leaves, height 40 cm, flowers June/October, sun semi/shade.

A range of geranium plants, attractively priced were snapped up by members following the talk.
