Behind the scenes at our gardens: Caring for Dyffryn over autumn

Ever wondered what it takes to keep our gardens in tip-top shape over the seasons? Go behind the scenes at Dyffryn with Head Gardener Chris Flynn and his team of gardeners and volunteers to discover what it takes to care for one of the most important gardens in the country.

They’ll be revealing the year-round challenges and joys involved in caring for these 55 acres of gardens, set in the Vale of Glamorgan and their plans to restore them to their former glory.

Dyffryn Gardens is one of the finest examples of Edwardian garden design, reflecting the opulence and grandeur of the period in which it was created. The gardens were the vision of coal magnate John Cory and his son Reginald, a passionate amateur gardener and plant collector.

Thanks to the enthusiasm of Reginald, Dyffryn was all about the brightest, rarest plants and quirky design which Chris and his team are working to restore. The dream of the gardening team is to evoke Dyffryn’s short-lived heyday between the wars.

What’s going on in the gardens over autumn?

As early autumn arrives, the borders and pot displays are still a riot of colour and the kitchen garden is a hive of activity.

Don’t miss the dahlias

Dyffryn is big on dahlias and now is the perfect time to see them at their best. Reginald Cory was a great dahlia enthusiast and became President of the Dahlia Society.

At Dyffryn he created large trial beds to grow new cultivars and in this spirit, Chris and his team have reinstated a trial dahlia border, as well as filling beds and pots with dahlias. These include some old varieties, such as ‘Union Jack’, seen here, which are no longer widely available.

Pots of colour

Hazel Robinson oversees all the plant propagation and the orchid house display. You’ll find magnificent floral designs in pots all around the garden, full of colourful begonias, fuchsias, salvias and annuals, all in the spirit of the garden’s opulent past.

Hazel explains, 'The big displays can keep going until November with copious dead-heading and watering. Behind the scenes we take the containers apart and put them back together again to freshen them up. We inherited over 1,000 dahlias which all needed identifying and labelling, one of my biggest tasks when I arrived at Dyffryn.’

The rarer dahlias are lifted after the first frosts and stored until the following spring but other varieties are sold off to visitors, so look out for a dahlia bargain in the shop this autumn.

What’s happening in the kitchen garden?

The kitchen garden is buzzing with activity in autumn. You’ll always find something unusual growing here and some of the weird and wonderful vegetables are now ready to harvest, including South American crops such as the oca. In the Andes, oca is the most widely cultivated tuber after the potato and the small, pink tubers are delicious raw in salads.

It’s not all about picking crops, plenty of planting goes on in the autumn too. Japanese over-wintering onions ‘Paris White’ are very hardy and will be sown this autumn as will the French variety of lettuce ‘Marvel of Four Seasons’.

Last chance to see

Look out for the eye-catching succulent border on the south terrace behind the house. These sun loving plants thrive in this sheltered spot, their architectural forms create bold patterns against the gravel. A succulent border featured here during the garden’s heyday in the 1920s.

All these tender plants will be carefully removed, potted up and placed in a frost-free environment over the winter, so this is the last chance to see them before the colder nights set in.
