winter – Charlton and Blackheath Amateur Horticultural Society

January 2026 Meeting and Show Table

Our first meeting of 2026 welcomed Everett Leeds as our speaker. A Clematis expert, Everett gave an entertaining talk and also sold seeds of some of the Clematis he discussed.

As usual, members enjoyed refreshments, took part in the raffle, shared their garden-related resolutions for 2026 and, of course, there was the regular Show Table. Six members took part with a wide variety of entries. We hope that as Spring gets going more members will be keen to show off and share their plants that are looking good each month.

Pat’s 10 jobs for January 2026

1. If you can brave the cold and wet it’s time to winter prune that Wisteria by cutting back all long whippy branches to within two buds of the main framework, so you can shape the plant for flowering.
More information on Wisteria pruning, including a video, from the RHS.

2. Any form of mulch is good on the soil now, in the form of your own homemade or bought compost, or even leaf mould if you have it. If you can’t face lightly forking it in, the worms will do it for you.

New Year flowers in Members’ Gardens

Following on from the New Year’s Day Flower Count in Charlton House Gardens, several members did their own Flower Count, and reported some surprising (and not-so-surprising) discoveries.

New Year's Day flowers in Ali H's garden (Chaenomeles, Geum, Hebe, Primula) — Japanese quince, water avens, elephants’ ears, Geranium, winter jasmine, Mexican fleabane, Viburnum bodnantense, Hebe, primrose, Salvia ‘Amistad’, Cyclamen coum, rose, brown-eyed Susan, Mexican orange blossom and laurustinus in Ali H’s garden

New Year's Day flowers in Ali H's garden (Bergenia, Geranium, Salvia, Cyclamen) — Japanese quince, water avens, elephants’ ears, Geranium, winter jasmine, Mexican fleabane, Viburnum bodnantense, Hebe, primrose, Salvia ‘Amistad’, Cyclamen coum, rose, brown-eyed Susan, Mexican orange blossom and laurustinus in Ali H’s garden

The winter-flowering shrubs were of course out in force (Camellia, Jasminum nudiflorum – winter jasmine, Skimmia japonica, Viburnum – both V. bodnantense and V. tinus, Clematis ‘Freckles’ and Daphne odora), as were the hellebores (though mine have remained resolutely in bud with not a single one opening yet!). Mandy A’s Loropetalum (Chinese witchhazel) was in flower, as were several people’s Hebes. My Chaenomeles japonica (Japanese quince) was covered in fruits, but still producing the odd confused flower too, along with a nearby Geranium macrorrhizum and Geum rivale.

New Year 2026 Flower Count at Charlton House Gardens

On a perishingly cold day – encouraged by a wintry sun – the intrepid Garden Volunteers ventured out on their mission to spot which brave flowers are showing off in the gardens this new year, 2026.

This is the third year we have undertaken a flower count, so we should know roughly what to expect. UK weather data shows that 2025 was the sunniest on record, and probably the warmest too. Here in the depths of winter, it’s easy to forget the unprecedented spring sunshine and incredibly hot summer that we’ve had. This is bound to have disrupted plant lifecycles and confused some into flowering at the wrong time.

Plant(s) of the Month: December flowers

What a mild 2025 December we are having! So mild, the weather is confusing some plants, such as lavender, Calendula and yellow-flowered Phlomis, out in flower at present.

One of the joys of winter is admiring all the window boxes, the wide variety of beautiful Christmas door-wreaths and observing what’s flowering in front gardens whilst out strolling.

10 Things for December 2025

December is a month when the garden often takes a back seat, and when Pat deserves a break from helping you all with your garden jobs, so the CABAHS Committee have come up with a list of 10 Things that they are doing this month in, from, or for their gardens.

Members’ gardens: virtual wreaths

Everyone enjoyed seeing the autumn colour in CABAHS members gardens, so we thought we’d like to see some more – this time on the theme of ‘ingredients for a winter wreath’. People submitted photographs of evergreen shrubs and perennials, winter flowers, berries and seedheads, and here they all are, compiled into virtual wreaths – complete with festive bows! If you contributed a photo, can you spot your plant or plants?

Plant of the Month: More Salvia! (November 2025)

Last week I was in Greenwich Park, in what was the Old Rose Garden for several decades, and now transformed into a fantastic herbaceous garden, a riot of colour, shapes and forms, tall grasses swaying and intermingling flowering shrubs (find out more about this transformation). I had gone there to see one specific Salvia – and what a show they were putting on!

November 2025 Meeting and Show Table

CABAHS Show Table, November 2025 — So much colour in November!

There was a great turn out for CABAHS’ last meeting of 2025. As usual, there were refreshments (this month featuring mini-stollen and mince pies!), also a plant sales table, a raffle, the Show Table and – the main event – an engaging talk from Dr David Marsh, garden historian and blogger.

Visit to the Royal Botanic Garden, Edinburgh

I spent a weekend this February in Edinburgh, and came across this interesting doorstep display on my travels around the city. Some new ideas for displaying your succulents …!

I also visited the Royal Botanic Garden. The morning I visited was bright, cold and calm, in stark contrast to the previous weekend when the garden had been ravaged by storm Eowyn. The sad remains of the garden’s tallest tree – a 166 year-old conifer – were clear to see.

The sun was shining and the sky a bright blue but the frost remained in the shadier parts of the beds and the Rhododendrons had bowed their leaves to protect themselves from the cold. But they were also covered in buds, waiting to burst forth in a few weeks time.
