1. Time to cut back Buddleja davidii hard… don’t be timid, take it right back to 40cm to a pair of buds. If you want a taller plant make the cuts higher up the stem. It will grow back in no time. The prunings make good hardwood cuttings and root easily straight in the ground.

2. You can pot up Dahlia tubers now by placing in pots or trays of peat-free compost in a frost-free place, and water once with no need to water again until shoots appear. Make sure the tubers are firm with no sign of rot.
It’s celebration time for the Royal Botanic Gardens, Kew, as this is the 30th year of their much-loved Orchid exhibition, set within the rare and exotic planting in the Princess of Wales Conservatory.

This year, China is the inspiration for the exhibition, in particular the Yunnan Province, where 1,000 species of Orchid are to be found.
So far February 2026 has been very wet, with heavy and prolonged downpours, which has restricted everyone’s garden visits, including mine. So I’ve had help this month from Ali H (many thanks) in seeking out winter-flowering specimens that are looking at their finest at the moment and hopefully will be of interest to you.
Originating from China and the Himalayan regions, Edgeworthia chrysantha is related to the Daphne family and I am not surprised as the flower clusters are extremely fragrant. They appear on the tips of bare stems in late winter, then in spring covered in foliage, consisting of attractive slender leaves, making a nice rounded shape to fit within planting schemes.
1. It’s time to prune your Group 3 Clematis (the Viticella and Jackmanii type) to tackle tangled growth at the base so they can grow away strongly. Take all growth back hard to about 6 to 12 inches above the ground, cutting above a leaf joint. Then give them a feed and a mulch. It seems drastic but they respond well and will grow quickly. If it’s a fairly new plant check around the base for slugs which can quickly eat any weak new growth.

2. Cut back all spent foliage on grasses making sure not to snip emerging shoots. And look out for any seedlings to pot up for our plant sales table if you don’t want them!
On Christmas Eve 2025, after enjoying a treat of delicious coffee and mince pies, we were shown Karen S’s very stunning red-veined Abutilon, growing extremely happily in the shade, on the north-facing side of the garden. Covered in glowing, pendulous, lantern-like flowers amongst its dark-green foliage , the shrub lit up the garden during those dark, December days.
This very healthy shrub with maple-like leaves, had been cut back hard some time ago and had grown very quickly. It was a cutting from Margaret T’s garden two or three years ago. Its growth was very impressive indeed. But before that, the cuttings originally came from North London some years ago, from a plant-lover’s garden. One Abutilon in this garden was seen growing happily as a tall shrub/small tree beneath a mature tree, thus receiving a fair amount of shade and protection, which I think is necessary, as Abutilon species originated from tropical and subtropical regions of South America.
Abutilons have a long-flowering period in London, in bloom from early-to-mid summer and again in early winter. Karen’s shrub is still flowering now in January, but the prolonged cold snap earlier this month has, naturally, affected it – not as upright as it was but still continuing to bloom, although the flower colour is no longer quite as vivid. Let’s hope it warms up and recovers quickly. I know how it feels!
In addition to gathering members’ personal gardening resolutions for 2026, our January meeting also launched the Committee’s proposal for a CABAHS-wide resolution for the year, inspired by Plant Heritage’s search for ‘missing collectors’.
The best way to save plants is to cultivate and propagate them, then share them with others.
“Amaryllis (Hippeastrum) are considered naff by some – their flowers being so spectacularly over the top and being so widely available in supermarkets. But I think their spectacular-ness is attractive and grow them every year. I hope this photograph of the Amaryllis that I have grown this year will encourage those who do not already grow them to do so. Perhaps we could have an annual Amaryllis competition at CABAHS!”
At our January meeting, members were asked to share – anonymously – their garden-related resolutions for the coming year. In addition, the CABAHS Committee put forward a suggestion for a CABAHS-wide resolution for 2026 (more on this in a separate post).
A fine, wise, and hopefully achievable range of planned actions were submitted, with members resolving to complete practical tasks that are easily put off or forgotten, right through to adjusting their attitudes / approaches to their gardens.
On Monday we welcomed Everett Leeds who gave us an amusing and highly informative talk about the prolific world of Clematis. He has been involved with Clematis for many years through growing, speaking and writing about them. He has been the Chairman of the British Clematis Society four times and is co-author of The Illustrated Encyclopaedia of Clematis . Everett’s enthusiasm for the genus was highlighted when he shared a photo of his former home with the front fence, hedges and trees completely swamped by a 120 foot long and 40 foot high ‘monstrous’ C. Montana. After cutting this completely away, he planted another!
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.
