Old Pond Garden Diary Update (April-December 2025)

As we come up to Christmas and the end of 2025, this is a great time to look back at how the ‘Old Pond Garden’ (OPG) project has fared this year.

(plus 27 garden volunteers!)

Of course, it’s not just the ‘Old Pond Garden’ project any longer, as volunteer work now covers the whole estate, but we are still fond of the OPG tag. Since April, the Garden Volunteer scheme has been run by Royal Greenwich Heritage Trust (RGHT), however considering 80% of volunteers are also CABAHS members, it’s fair to say we are still very interested and still very involved.

Sharon has taken on the crucial role of Volunteer Lead for RGHT and works with Head Gardener Jason to make sure everything runs smoothly. She posts lovely updates on the garden team’s WhatsApp after every session, keeping us all on track, and sends a report off to RGHT every month.

Here are some highlights picked from Sharon’s reports of the past few months, I make no apology that this is a rather long post – we have done a lot!

Belfast Botanic Gardens

I have been spending some time recently in Northern Ireland, and was enchanted to find the Belfast Botanic Gardens are right on my doorstep here.. just waiting to be explored.

The gardens started in 1828, when the “Belfast Botanic and Horticultural Society” was formed and a 14 acre site purchased. The Palm House was built in 1839 by ironmaster Richard Turner of Dublin, who went on to build the Palm House at Kew a few years later! If this one was a practice run, it is still really impressive.

It is not large, but cleverly designed to incorporate a Cool Wing, a central Dome which is sub-tropical, and a Tropical wing, so it can house a wide range of plants. Sadly it was closed for repairs on the day of my visit, courtesy of the recent winter storms.

There is another glasshouse on the site, the Tropical Ravine House, which is just amazing. It was built by “the Head Gardener and his staff” (Jason & the Garden volunteers – there’s an idea!) and was finished in 1889. Uniquely constructed into a hillside, so the visitor walks around a balcony and looks down into a moist glen filled with tropical planting.

It was renovated in 2019 with help from the Friends of Belfast Botanic Gardens, who clearly play a large part in supporting and maintaining these gardens. They have also created a fascinating new Global Medicine Garden just to the side of the glasshouse. https://fobbg.co.uk/

January 2025 Talk: Succession Planting for a Long Season

Our first meeting of 2025 was very well attended. The speaker and the topic obviously attracted a good audience. The Show Table received a good selection of displays, with Jean’s a worthy winner of Best on the Table.

Our speaker, Fergus Garrett, the highly influential plantsman and horticulturalist, has been Head Gardener at the internationally acclaimed Great Dixter Garden in Northiam, East Sussex since 1993 and is the CEO of the Great Dixter Charitable Trust. He gave an excellent, wide-ranging talk on how to keep our gardens looking vibrant and spectacular all the year round. He explained how to plant for a long flowering season with plants co-existing in one place, but performing at different times. He used photographs of the spectacular gardens at Great Dixter to illustrate his points. He said Great Dixter had the advantage of scale and greenhouses but it is possible to scale down what they do at Great Dixter and use their scheme in our own gardens with minimal labour.

He particularly used the magnificent long border at Great Dixter as an example of how to plan a long flowering season. How to use structural under-planting, interlaying and interplanting with bulbs, self-sowers, perennials, clumps of bedding plants and climbers.

Sparkle in the Park at Charlton House

The park is sparkling! Our visit to the first night of Sparkle was very impressive, the light installations have been fitted really thoughtfully around the layout of Charlton House grounds.

The trail starts by the Mulberry, and the avenue of trees have been lit up beautifully as you walk through a snow storm and then past installations based on Christmases in Ukraine, St Lucia and Lagos. We loved the Ukrainian stars decorated by local schoolchildren.

At the end of the avenue you turn back towards the House – and can’t miss the glowing giant spheres (sorry, I didn’t note down the artistic reasoning for those, but they are certainly eye-catching!) and beautiful blue and white snowflakes played onto the back of the House.

King John’s Nursery and Garden, Etchingham, Sussex

On a gloriously sunny day in May, a visit was paid to the garden at King John’s Nursery. This ‘naturalistic’ garden is set within a beautiful landscape of ancient trees and meadows. We were given a laminated map of the garden layout and proceeded through the old honeysuckle-clad, wrought-iron gate to the garden beyond. This led us to the first garden room, beautifully planted in soft-pinks, the focal point being a circular, brick-built pond, fed by an imaginative water-gully. This led us into the gravel garden room, consisting of sun-loving and tender plants displayed to great effect on a slab-table, an artefact that many of us would love to possess for our own gardens!

From there we entered a magical place – a charming meadow with mauve-blue spires of camassias threading through and rising above the grasses, a stunning contrast to the shades of green all around. White-flowered camassias were in bud, ready to take over and bloom in the next week or so. In one corner of the meadow sat a toadstool circle, an enchanting addition for children to let their imaginations run wild. We exit beneath the clipped hedge archway into a larger meadow which includes an herbaceous long border, consisting of many taller plants such as grasses and flowering angelica. We follow the path around, to a shaded woodland dell and admire the luminosity of the rhododendron’s stunning white flowers by a gateway entrance, cow-parsley billowing alongside solomon’s seal and pass beneath the 350-year-old oak tree. Amongst the grasses, glistening in the sun, wild orchids are to be admired. We sat on the bench to absorb the idyllic setting before us, noticing glimpses of an old apple orchard beyond the boundary.

October 2023 Talk: The Middle-Sized Garden

Fifty three people attended our October meeting in the Old Library, enjoying refreshments, the raffle, the plant sale and the Show Table, as well as an interesting talk. The Best on the Show Table was Annie H’s display of Dahlia flowers and Helichrysum.

The talk on the Middle-Sized Garden was a first for CABAHS as it was given by a blogger, Alexandra Campbell who describes herself as a blogger, YouTuber, journalist and author.

For most of her career Alexandra worked as a journalist at journals such as Harpers, Queen and She. But when the introduction of IT led to the drying up of hard print journalism work she embarked on a second career teaching herself blogging and videoing. She now blogs at the Middle-Sized Garden blog which gives advice and tips on gardening. It is one of the top ten gardening blogs in the UK with over a million viewers and covers garden design, middle-sized gardens and expert interviews and tips. She also has five million viewers on her YouTube site.

Great Dixter

Throughout the year Great Dixter hold various events for their Friends membership. So, on yet another dismal July evening this year, Pat and I drove to Sussex. The evening began with drinks and canapes and a talk from Fergus which should have been held on the front lawn but, due to the inclement weather, was inside in the Great Hall. Three boxes of plants from the nursery, designed for dry, wet and shady aspects of the garden, were raffled at £5.00 a ticket. Surprisingly, as Fergus was talking, the sun came out and what could have been a wet evening turned into a very pleasant one. Although the colour of the sky in the photo demonstrates it was still fairly cloudy!

We had arrived slightly early, so were already able to explore the garden which is always full of surprises. The phlox were particularly beautiful and Pat and I were trying to note varieties for our own gardens! Following Fergus’ talk, which was generally about the work of Great Dixter and collaborative projects that were ongoing including one with Hastings council, we divided up into groups according to our chosen tour/talk. Each one of these was conducted by one of the students at Great Dixter. Pat and I had opted for the Long Border and Jungle Garden (although we popped out of the latter and into the Nursery!). The students are articulate and engaging and certainly know their material. Having watched Fergus’ lectures on the Long Border, it was interesting to see this in practice and explained to us by Andrew Wiley, one of the Chanticleer Scholars. A particularly interesting stand of Salvia Indigo Spires was a huge clump of individual cuttings rather than one big plant. Also in use was a lovely creamy apricot Cosmos (Cosmos bipinnatus Apricotta) – a colour which we have seen a lot in other gardens this year and can be picked out in the photo (one to be ordered for sowing next year!). We always leave these gardens full of ideas and plans!

OPG Diary – November/December

Welcome to Winter in the garden, and all the many lovely shades of brown. So many seedheads, grasses and winter leaves are keeping the Old Pond Garden looking beautiful. November was incredibly wet but the Volunteers tackled some great projects. The shrubbery in the front car park has benefitted from a comprehensive weed and some marathon pruning. A soakaway was dug by the steps to the Montessori Nursery, so that parents can pick up the kids without needing waders. Then it was on to bulb planting – we predict a River of Purple (Alliums) through the beds next year!

OPG Diary – September /October

September started off with the tail end of The Drought and as it became wetter the Volunteers were very grateful to get back to some proper gardening. The great news is that we hardly lost any plants at all.

The Peace Garden has benefited from our attention, with the last of the annoying stones on the path edges being removed, and work on the shrubs and climbers along the walls making them look much more defined and trim.

In the Old Pond Garden, many perennials went to seed earlier than usual, due to the drought, but the seedheads are quite spectacular.

The Volunteers were thrilled to receive a donation of jars of honey from the Charlton House Beekeepers. The bees had a bumper year, partly due to our lovely gardens. To stop any squabbling, we held a raffle to decide who got a jar and the happy winners are shown here:

Pashley Manor Trip

A lovely day was had by all, despite the rain, for our visit to Pashley Manor Gardens, on Wednesday 14 September. The first wow factor was the magnificent and absolutely huge 500-year-old spreading oak tree that is the same age as the frontage of the Manor House. The second wow factor are the gardens: exquisitely beautiful, divided into several colour-co-ordinated garden ‘rooms’ which lead to the fabulous terrace, with sweeping views of the long borders, lawns, lake (once a moat) and surrounding trees to the countryside beyond. After a refreshing coffee, many joined a half-hour gardener’s dahlia ‘talk and walk’ around sections of the garden’s long borders. I loved the gardens so much that I am aiming to visit again on a sunny day so that I can relax on the terrace and absorb the spirit of the place.
