Well done to CABAHS members who managed to find something to display on the Show Table in the depths of freezing January, it was lovely to see. Congratulations to Sian for winning this month’s Best on the Table prize with her camellias.

To be honest it has been so wet and now so cold that the ground is frozen but if conditions return to normal maybe you can try some of the following…..we live in hope!
1. Today according to the RHS is National Houseplant Appreciation Day so try giving those houseplants some attention and if they’re not looking good, treat yourself to a new one checking you have the right conditions for it.
2. Remove old hellebore leaves right back to the base to show off their flowers and to stop any leaf spot or other diseases from spreading.
3. All my violas in my front window box have died and a good gardening friend reminded me it could be vine weevil larvae chewing the roots which I haven’t had for ages so turn out the window box and check for those grubs and replace with fresh compost.
4. Start pruning roses cutting back with a slanting cut to above a bud and use the resulting prunings for cuttings 6 to 12 inches long and insert into either a pot or the ground so that 2/3 of the cutting are below the soil. They take a good while to root but its worth the free plants if they root.
5. Winter prune wisteria by cutting back shoots to 3 or 4 buds from the main stem.
6. Cut back really tatty herbaceous plants but leave anything with hollow stems or stems and foliage that may harbour overwintering insects. I started cutting back a bay tree until I saw the ladybirds amongst the stems.
7. Seed potatoes can be chitted from now on by placing them so they don’t touch in boxes, egg cartons are ideal, and placing in a light frost free place. Don’t forget to label the variety.
8. Prune established soft fruit bushes such as gooseberries, red and white currants removing any dead wood and cutting back main shoots by a quarter. If grown as a bush aim for a goblet shape with an open centre to aid air circulation.
9. Look at your seed catalogues and order anything you especially want before they run out.
10. Make sure to have some scented flowering shrubs either in the garden or in pots for pollinators to include winter honeysuckle, sarcococca, daphne and viburnham and aim to plant some by your door so you can catch the scent.
Happy gardening all!

Ed: The RHS has a shop at Bluewater, perfect for browsing for some houseplant updates, all UK grown. (Note they don’t take National Garden Vouchers though)
As much as I love this perennial and have planted many clumps over the years, I find it struggles in my clay soil. My now, one-and-only plant, obviously needs more sun and perhaps lighter soil, as it has flowered perhaps only once this winter and that was on 23rd November, when I took the photograph below. But Margaret T’s winter irises have been really putting on a display, with her two clumps producing 2-3 flowers at a time, on and off since December. And these will carry on flowering well into March. I’ve seen them flowering profusely when nestled against sunny, front elevations, in poor soil. But in Margaret T’s garden, the soil is rich from regular additions of compost and manure and you can see by her photograph that she has healthy, plump plants.

As a special, early, Christmas treat, on a very mild evening on 30th November 2023, a friend and I visited Greenwich Council’s Light Festival, the magical Sparkle in the Park, held this year at Avery Hill Park. This was Greenwich Council’s 4th Sparkle in the Park event, this time featuring many new displays, and it was nice to see the many artists being acknowledged for their spectacular creations. The excitement was palpable as the winter wonderland trail lead visitors through an illumination of lights and enchanting displays amongst the trees.
Our first volunteer session of 2024 fell on a wet and windy day (a Severe Weather Warning day in fact), so we decided to abandon gardening tasks and go for a bracing walk around the estate to spot for plants in flower and work off a few mince pies.
Although a lot of our findings were to be expected (Primroses, Hellebores, Mahonia) others definitely felt wrong – Penstemon Garnet, you should NOT be out! It will be interesting to do the same exercise next year and compare. In the meantime, below are some cheering pictures of our walk:
I think you could say that the Mahonia in the Glade was a “Star Plant” for this time of year.
Penstemon ‘Garnet’, top left, then Achillea ‘Cerise Queen’, Sarcococca confusa (you should smell this!) and Viburnum bodnantense ‘Dawn’.

Unbelievably, the last “diary” post I made about the Volunteer scheme was back in March, when we had just started to dig up the palms in the Front Lawn and hyacinths were just coming in to flower. The year is not quite done, but the Volunteers have worked a total of 2,724 hours, I feel quite tired just thinking about it!
We have posted about our events, like Bunnies in the Beds, but not about the important work that goes on behind the scenes, under Jason’s direction. So in April, we pruned the Pomegranates and the overgrown parts of the Wilderness and front shrubberies were tackled. Paths were mown through the grassy areas and Jason got RBG’s agreement not to mow in certain parts of the estate – saving them time and making our life greener.
The final palm roots had been removed by May (they were HUGE!) and preparation and planting started in the front beds. The Peace Garden beds were re-shaped, they will be better for functions like weddings and coincidentally there is now more “bed” available to plant into! The Wilderness paths really came into their own as the grass around them became taller. When he wasn’t mowing the paths, Pete bravely tackled the area around the Substation, which was full of very thorny shrubs like Pyracantha and Berberis, really unpleasant to work with. The rose beds at the front were tidied and some major Long Border weeding started.

At this ho-ho jolly time of year I expect everyone is looking forward to getting some good Christmas gardening presents! (Yes? No? Bah Humbug?)
I asked the committee what ideas they have this year, and we came up with the selection below. I hope it gives you some inspiration, or at least is something you can use when asked the dreaded question “What would you like for Christmas this year?”
Books: The Power of Trees by Peter Wohlleben. This was reviewed recently in the RHS magazine and I have seen it recommended elsewhere too. Waterstones says it is “a manifesto aimed at preserving the future of our forests and debunking accepted wisdom about tree-planting schemes”.
Books: What did the Tree See by Charlotte Guillain. I bought this for my grandson, it’s one of those childrens books that covers a huge age range. He is far too young to understand the whole thing at 3, but loves the pictures and storytelling. Much older children will like the historical side of it. And OAP’s like me love it too!
Continue reading Are we Feeling Christmas-y yet?Timothy Walker is a botanist with an extensive career in horticulture. He is a former Director of Oxford Botanical Gardens and still lectures at Somerville and Pembroke Colleges as well as being a Fellow of the Linnean Society and winner of four Chelsea gold medals. He came to our attention as the presenter of the BBC 4 television series Botany – a Blooming History. He gave an entertaining and informative talk which was very well received by the audience.
Like all living organisms, plants aim to ensure offspring for the next generation. Timothy described the sexual life of plants as the movement of pollen along the stem from the male anther of a flower to the female stigma to allow fertilisation. He put his discussion within the context of Darwinian theory of the Origin of the Species and Natural Selection and said pollination is less subservient than normally assumed.
He described a variety of stratagems for pollination and ways plants have developed to ensure it happens. Nature abhors inbreeding and, because of genetic problems associated with self pollination, tries to avoid it.
Continue reading November 2023 Talk: Sex, Lies and PutrefactionDuring September 2023 I revisited the newly-built Wellbeing Garden, located at the rear of University Hospital, Lewisham.
There have been some exciting changes and the most notable is the large, beautifully-built, pergola that pulls the whole garden together. The pergola not only provides shelter but acts as a meeting place for various classes, including the Gardening Club. Some of the structure’s uprights are decorated with painted terracotta tiles, showcasing talented and creative individuals.
The planting in the garden had matured, and, being autumn, the grasses were in their prime, growing alongside the flowering stars of pink Tulbaghia violacea. I noticed a Snow Drop tree (Halesia diptera) and an additional small tree, Heptacodium miconioides, a species I had never seen before. The tree was displaying clusters of prominent, white, flowers with an intoxicating perfume, so, for me, this was an exciting find.

Another wonderful Show Table at our November meeting, with beautiful Autumnal overtones. Winner of “Best on the Table” this month was Maggie, with her “Not quite Christmas” cactus in full flow. There were some lovely late Salvias and Carolyn’s Persicaria gave a real “pop” of pink to the table. Lynda’s asparagus (which won the Wildcard at the Spring Show) keeps on giving, with leaves a zingy yellow this month.
Members also brought in colourful leaves and flowers to display as a mandala, and Annie added hers to make a pretty Show Table exhibit.
A great display everyone!
