Beth Chatto’s Plants and Gardens, September 2026
Last Friday, a full coach of CABAHS members took another trip to Essex, this time to see Beth Chatto’s Plants and Gardens. The last group visit was in 2021 and the irony of visiting a world-famous dry garden in torrential rain was not lost on those who attended then. A heavy downpour on Friday’s journey made us wonder if we might be reliving the experience, but it was brief and our whole visit was dry.
Most well-known is the Gravel Garden, which was developed in the 1990s on the former car park – at a high point in the gardens which, in Essex, are in one of the driest parts of the country. But the site has a much more varied topography and ecology than just the dry garden. Much of the site was actually boggy and Beth and Andrew Chatto carved ponds in the lowest areas. This meant that we saw green, green lawns in an area – the Water Garden – where the water table, even after this summer drought, is high.
A visit to Great Dixter, August 2026
The weather was forecast to be wet and possibly stormy, so we travelled with raincoats and umbrellas and extra layers of clothes. As it turned out, the weather was hot and sunny – a perfect day for garden visiting.
Unlike some other gardens, including many of our own, Dixter was full of colour and a profusion of planting. Nathaniel Lloyd and Edwin Lutyens had had the foresight to install a reservoir when the gardens were first built and this has served them well. The gardening team have focussed watering on new planting and stressed areas, which has clearly been a successful strategy. The intensively gardened areas like the Long Border have been watered end to end four times since January and the effects of this can be seen in the photos below.
Plant of the Month: Solanum laxum ‘Crèche du Pape’ (August 2026)
Long-flowering, no-fuss species/varieties are ever so handy to have in our gardens, especially roses and climbers, which I’ve not watered at all this summer – a big bonus! One of these, Solanum ‘Crèche du Pape’, probably purchased 16-17 years ago, is such a plant – no trouble at all and flowering for months at a time. I wouldn’t be without it.
Andrew Salter’s Barn Garden
Last weekend I visited Andrew Salter’s garden near Canterbury in Kent (@big_drewland on Instagram). Having announced the open garden date a mere three weeks into the drought, he then considered postponing / cancelling by the time another rainless, hot month had passed. I am very glad he did not, as even drought-scorched, crispy and hot, the place bewitched me.

It was a pleasure to welcome Selina Ozanne to our August meeting to hear about her work as Head Gardener for The Exchange, Erith, a community led arts and craft organisation based in the town’s former Carnegie library.
The refurbished listed building is now home to craft production workshops, a cafe and shop, along with a varied programme of community events.
The Exchange gardens were designed by Chelsea Gold medal winner Sarah Price. The site has various challenges from a sloping roadside front garden exposed to sun and wind from the Thames, to a woodland-edge rear garden with a steep incline. Sarah’s design pulls together these diverse elements together using sustainable materials and matrix planting to make the garden flow coherently in a way that everyone can access.
August 2026 Meeting and Show Table
The drought continues and we weren’t sure what members would be able to bring to the Show Table this month – but they came up trumps with extraordinary vegetables, beautiful posies and healthy specimen plants.

| NB: We have just heard about an RHS survey about the impact of the recent weather: RHS Climate Change Resilience: Heatwave Impact on Gardens which has to be completed by 30 September 2026. |
Following on from Pat’s ’10 Jobs…’ tips on coping with drought and heat, we asked CABAHS members to share which plants had proved to be ‘winners’ and ‘losers’ in the recent extreme weather, to help us all make climate-change-appropriate choices in the future.
A summary: After the spring AND summer drought of 2025 (with four of the previous five years being the warmest on record), we experienced a cold November and a wet winter (the 4th wettest on record for Southern England), with the addition of unusually low light levels in early spring. We have now had extreme drought (no rain at all since early June and counting – and there were long dry periods before that too) and, so far, several heatwaves (which is counted as three or more consecutive days over 28 degrees in London – all have been in the 30s). Of course, the heatwaves may have counted six times (starting on 22 May, 19 June, 4 July, 28 July, 2 August and 9 August respectively) but the weather hasn’t exactly cooled off much in between. In addition, Thames Water declared a hosepipe ban beginning on 23 July (though watering cans and drip-feed systems are not banned) and there’s precious little rain showing in the forecast even now.

1. To be honest we know at the moment with the drought and the heat this column will be about the few things you can do to keep things alive. I am sure we will all have losses along the way, but remember all is not lost and will mean new planting opportunities for next year.
2. If you have weeds growing (even they are struggling at the moment!), pull out and place around plants to help hold the moisture in the soil. Make sure the weeds haven’t gone to seed and, if they have, pull the seedheads off and dispose of them.
3. Mulch the soil with anything you have to hand: your own compost, fallen leaves (as there seem to be so many) but make sure the soil is damp first so you can help lock in the moisture.

Being very partial to soft-orange and terracotta-orange coloured flowers, I am delighted that from my kitchen I can enjoy the vibrant, terracotta-orange flowers of the statuesque Tithonia rotundifolia. The flowers are an absolute delight, lighting up my garden at the moment, and, hopefully will do so until October.
I’ve never tried sowing seed of this wonderful variety but I will experiment next year. I spied this plant for sale when visiting one of the lovely gardens open for the Greenwich and Bexley Hospice Open Gardens, held once again in June, to the delight of local residents.
