Extreme weeding – fighting an aquatic invader at Claremont

In an extreme case of weeding, amphibious tractors are this week tackling almost 16 tonnes of invasive weed in the lake at the National Trust’s Claremont Landscape Garden.

The vehicles, an amphibious cross between a tractor and a tank, are armed with giant rakes to remove the carpet of Crassula helmsii – also known as New Zealand Pigmyweed – that is covering the man-made serpentine lake at the Surrey garden.

The non-native weed reproduces rapidly and, without natural competition in the UK, can quickly spread out of control, overtaking a waterbody and blocking out light for other flora and fauna.

The harvesters have been busy collecting the weed and depositing it in a huge pile on the island in the centre of the lake. Here it will rot down quickly, creating compost, while allowing any fish and invertebrates scooped up to make their way back into the lake.

The lake is 27,000 m2 and it could take almost two weeks for the surface to be completely clear of the aquatic invader. There is currently no known way to entirely eradicate the weed, so gardeners at Claremont will manually remove the weed throughout the year using nets and waders.

Tim Rayfield, Senior Gardener at Claremont, said: “By using the large harvesters, we’re able to control the Crassula with minimum impact on the lake and its eco system.

“It’s one of the more unusual ways that we conserve this amazing landscape garden, and it’s great to be able to see the trees reflected in the water once again.”

TOP PRIZES FOR NATIONAL TRUST GARDENS

Horticulturalists from two National Trust gardens have been awarded top prizes in the Horticulture Week Custodian Awards 2017.

Croome, Worcestershire, was a double-award winner, taking home the ‘Best Parks Restoration/Development Project’ for the restoration of the 18th-century parkland, as well as the ‘Best Visitor-Engagement Event’ award for ‘Brown at Work’.  Bodnant Garden, Conwy, scooped the ‘Best Gardens Restoration/Development’ for the restoration of The Bath area of the Victorian garden.

The conservation charity looks after 173 registered parks and gardens across England, Wales and Northern Ireland, including 38 listed as Grade I.

Work to restore the parkland at Croome, ‘Capability’ Brown’s first large-scale commission, started when the National Trust acquired the park in 1996, following years of neglect and intensive arable farming.

Thanks to external funding of over £8 million from the Heritage Lottery Fund, Natural England, English Heritage and others, and nearly 20 years of hard work by a team of gardeners, rangers and volunteers, the parkland has been returned to its 18th-century heyday.

A £230,000 donation from Monument 85 and Croome Court Appeal Committee enabled the reinstatement of the lost Chinese Bridge over the river. Thousands of trees have been returned to their original positions, follies and temples have been repaired and the river and lake have been dredged.

‘Brown at Work’, an Arts Council England funded project supported by the Landscape Institute and CB300 celebrations, was a miniature landscape created at Croome in summer 2016. Tonnes of sand and simple tools enabled visitors to form their own landscape masterpieces that could be sculpted and re-sculpted by visitors to help them understand the ‘created’ landscape in which they walked.

Michael Forster-Smith, Croome’s General Manager, said: “It is fantastic that the hard work of our gardens team has been recognised by this prestigious national award. With the support of a number of generous donations and grants, one of Brown’s finest works has been returned to its former glory.

“Last year’s ‘Brown at Work’ installation was a captivating way to bring Brown’s creation to life for our visitors. While there is still work to do to at Croome, this is a great moment to reflect on how much has been achieved in a relatively short period of time. Our restored parkland is, once again, a meaningful and special place for all those who love spending time at Croome.”

The National Trust’s third award of the night came courtesy of Bodnant Garden, Conwy. Winning the ‘Best Gardens Restoration/Development Project’ award for the two year restoration of The Bath, a Victorian ornamental pool below the front lawn of the mansion, Bodnant’s garden team was rewarded for returning The Bath to a miniature exotic paradise, as it would have been in the late 19th-century.

Plans to restore The Bath were given new impetus following the winter storms of 2013/14. When an old oak tree came down, damaging walls and ripping up flower beds in the process, horticulture students working and studying at Bodnant Garden were able to develop a new planting scheme in the nearby beds.

In 2016, the walls around The Bath were repaired, plants removed and a new tropical plant scheme was introduced to take advantage of the sheltered microclimate area provides.

Bill Warrell, Bodnant garden supervisor, said: “To go from the devastation of the 2013 storms to this award is fantastic. It’s a credit and a real boost to the gardeners, students and volunteers who put in a huge amount of work, both repairing and renovating this lovely old part of the formal garden.

“We took the opportunity to do something ambitious and to create something fun and colourful that was a little different to the rest of the garden, while reflecting the Bath’s history. The Bath’s sheltered microclimate offered us the ideal opportunity for a little experimentation. Visitors have loved the results too and we’ve had many wonderful comments.”

Four other National Trust gardens and parks were nominated for awards, including Hardwick Hall, Derbyshire; Quarry Bank, Cheshire; Emmetts Garden, Kent and Chartwell, Kent.

Mike Calnan, Head of Gardens for the National Trust, said “I’m delighted that the hard work of our horticulturalists and gardens and parks teams has been recognised with such prestigious awards and nominations. The teams that manage National Trust gardens and parks pride themselves on maintaining the highest standards of attention to historic detail, horticultural expertise and innovation while allowing our visitors to experience these incredible places for themselves.”

The winners were announced at a prestigious ceremony at Woburn Abbey House and Gardens Sculpture Gallery. Now in its second year, the Custodian Awards nominees were this year drawn from a list almost twice as long as the inaugural list in 2016.

The awards were judged by an independent panel including Professional Gardeners’ Guild (PGG) chair Tony Arnold, Horticulture Week technical editor Sally Drury, former City of London Corporation director of open spaces Sue Ireland, London Tree Officers Association executive member Dave Lofthouse and master gardener Alan Sargent.

Gardeners at Beningbrough Hall, Gallery and Gardens, near York, had to get their stepladders out this week to measure giant Echiums growing in the garden.

The plants, found in the Italian border at the National Trust-owned property, have reached a towering 4.3 metres high – the same height as a female giraffe.

Kate Wilkinson, the gardener tasked with measuring the plants, said: “It wasn’t as straightforward as simply getting a tape-measure out.  I had to climb a stepladder, and even then it wasn’t enough. With the measuring tape attached to the end of a bamboo cane, I was just about able to reach the top of these amazing plants”. Continue reading

1920s Arts and Crafts garden returns to its heyday as five year restoration is completed at Standen

A five year restoration project at one of the country’s most important Arts and Crafts gardens has been completed at the National Trust’s Standen in West Sussex.

The impressive house at Standen, with its breath-taking views over the High Weald and Weir Wood Reservoir, was designed for James Beale and his family in the late 19th century by leading Arts and Crafts architect Philip Webb.

The 12 acre hillside garden, however, was designed by Beale’s wife Margaret and saw its heyday in the 1920s. An accomplished gardener and plants-woman, Margaret was inspired by a world tour in 1906-07 and created a series of outdoor rooms at Standen, including a scented rose garden – the Rosery – and a lime tree walk, along with more exotic areas with bamboo, ponds and lush foliage.

Over ten years ago, a group of volunteers discovered the Beale family swimming pond while clearing out some overgrown bamboo in part of the garden. Following extensive research, the garden revival project began in 2012 and is one of the biggest that the conservation charity has undertaken.

 

James Masters, head gardener at Standen explains: “In the latter part of the 20th century, Standen’s gardens saw alterations and replanting which covered or removed some of the original features. When I was first investigating the undergrowth in areas of the gardens I realised there was much more than met the eye.

“Over the years our discoveries have included lost walls, a rock garden and rare and unusual plants all overgrown by the vigorous modern planting that had masked the original beauty of Margaret Beale’s design. So we were lucky to have a wealth of archive material that has helped us research how it would have looked, ranging from family photographs, maps and receipts, to Margaret’s garden diaries which she kept for over 40 years. These have enabled us to piece it together and bring the garden back to its best.”

Among the garden features that have been restored are:

 

  • The original swimming pond and rose garden growing Margaret Beale’s coveted China pink roses.
  • A fine oak trellis rebuilt to the original design by Philip Webb. Trellis is a feature in one of Arts and Crafts designer William Morris’ wallpaper designs which is used in the house.
  • Lime trees reinstated along Grandfather’s walk.
  • 10,000 tulips including rare varieties
  • The kitchen garden and the original espaliered apple trees.
  • New views opened from the top terrace across to the Ashdown Forest.
  • New Arts & Crafts inspired planting in the house courtyard.
  • The medieval quarry face revealed alongside the drive, which inspired the Beales to build Standen in this location.

The £500,000 funding for the restoration project included generous legacies to the Trust for the purpose of garden projects and properties in Sussex.

James Masters adds: “I look back at photographs from before we started the restoration to remind myself of the remarkable changes the team of staff and volunteers has made since then. We have worked so hard to do justice to this lovely lost garden and make it shine again and I hope our visitors will enjoy discovering something new down every path and around each corner.”

A new exhibition about the garden and its revival will be taking place in the house from 6 May to 3 September and will include many of Margaret Beale’s original documents that were used for the restoration. A tulip festival is also taking place and a midsummer celebration will include talks, teas and tours from 1 June.

Ahead of the curve: innovative 19th century curved glasshouse is restored to its former glory

A rare example of a 19th century curvilinear glasshouse has been restored at the National Trust’s Quarry Bank in Cheshire after a year-long restoration project.

The 1820s glasshouse was built to supply the owners of Quarry Bank mill, the Greg family, with tender fruit of the time, such as grapes and peaches. Its innovative design and use of modern technology sent a clear message to guests about the Gregs’ financial success and position in society.

Although the conservation charity acquired the 18th century cotton mill in 1939, it was only in 2010 that the kitchen garden was acquired by the Trust. The jewel in the crown of this walled garden was the severely damaged curvilinear glasshouse, a name given to the structure because of its unique curved roof.

National Trust garden teams in the south west [1] have conducted their annual flower count for Valentine’s Day and although spring seems to be on the way, just as we would expect, what is noticeable is how many scented plants are already out in flower at this early time of year.

Gardeners from across National Trust gardens in the south west recorded 1,737 plants blooming in this year’s 12th annual Valentine’s Flower Count, which is 34% down on last year’s figure of 2,644. However, while numbers are down on 2016, they are still higher than the previous three years [2]. Continue reading
