Tips to tackle deadly plant disease

Plants such as rhododendrons are affected by the disease

Advice on how to tackle a deadly plant disease has been offered to gardeners in Scotland.

The National Trust for Scotland is offering practical help following recent outbreaks of a disease that can affect plants such as rhododendron.

The charity has a set of tips for consumers with detailed guidance on how to deal with Phytophthora ramorum, also known as Sudden Oak Death,

The disease has so far been found in four Scottish Gardens.

Two examples were found at the National Trust for Scotland's Arduaine Garden and Inverewe Garden but it has affected many places in England and Wales.

A similar disease, called Phytophthora kernoviae, has also been detected in one non-National Trust garden.

Gardening specialists

The charity has played a leading role in addressing the problem of Phytophthora ramorum, ever since it was detected at Arduaine last October.

It has been working closely with the Scottish Government Rural Payments and Inspections Directorate (SGRPID) on how to manage the disease.

In partnership with the Royal Botanic Garden Edinburgh, the trust brought together its own gardening specialists from properties throughout Scotland, government authorities, the (English) National Trust and some private gardens, to share detailed practical knowledge.

TIPS FOR GARDENERS If woody plants seem to die quickly, check to see if they are among susceptible plants e.g. Viburnum, Rhododendron In affected areas disinfect tools and remove soil from boots and shoes Buy plants from a trusted source If you have any concerns about a plant contact SGRPID office Do not take cuttings from affected areas

Ann Steele, gardens and designed landscapes adviser for the trust, said: "This disease is still very rare in Scotland but it's been a problem in England, so gardeners should watch out if woody plants seem to die quickly, keep gardens and tools clean, buy your plants from a trusted source and if you're concerned, contact your local SGRPID office".

She said gardens that have been affected by the disease should display a notice telling visitors.

Visitors to gardens affected should make sure they stay on the paths, follow the signs and should not take any leaves or cuttings away with them.

Both Phytophthora ramorum and Phytophthora kernoviae can kill off some popular trees and shrubs, as well as causing damage to plant collections.

Sudden Oak Death was first discovered in the United States
