Preventing disease in hedge plants

Healthy hedges start with the right care. Learn why clean tools are essential to effectively prevent plant diseases.

Note on the battery system

On this page you can see tools and batteries from the AP system. With the launch of ALLPRO, we now have a new battery system that delivers next level power. With quick charging times and a longer working life, it is also 100% compatible with the previous AP system.

Overview: Disease prevention

  • The Bathurst Estate’s towering hedge, which is 14 metres high and 120 metres long, illustrates how thorough care can prevent diseases
  • Regular cleaning and care of tools prevents the transmission of pathogens
  • Sharp blades make precise cuts, which means hedges heal quickly
  • Regular hedge checks can detect diseases and damage at an early stage

Best practice: The world-famous hedge at Bathurst Estate

The famous hedge at Bathurst Estate in Cirencester, England, is an example of world-leading care. With a height of 14 metres and a length of 120 metres, it is the tallest yew hedge in the world according to the Guinness Book of Records.

The hedge planted in 1720 is cut once a year in the first two weeks of August – a complex process that takes about ten days and requires a lot of experience. While executing the work, forester Iain Garett and lead forester Oliver Murray carefully check the hedge for signs of diseases such as fungal infestations or injuries that could affect the health of the hedge. The hedge is over 300 years old, so regular care is essential to preserve the unique appearance and vitality of this living landmark.

“A thorough inspection is crucial to detect problems early and ensure the longevity of the hedge.”
Iain Garett, Forester at Bathurst Estate

    

Health risks to hedge plants

A number of factors can endanger the health of hedge plants:

  • Unclean tools:
    Dirty blades transmit pathogens such as fungi (for example, phytophthora root rot) or bacteria. Regular cleaning is particularly important if the tools are used in many different locations. 
  • Pests and climate change:
    Higher temperatures and longer periods of drought put plants under stress and make them more susceptible to disease. The professionals at Bathurst Estate report an increase in fungal infections due to changes in environmental conditions.
  • Injuries:
    Damage to plants due to improper cutting or damaged branches serve as entry points for pathogens.
  • Global trade:
    Importing plants increases the risk of introducing new pests and diseases.

At Bathurst Estate, one of the hedge sections showed signs of chlorosis – a yellowing of the needles caused by a local nutrient deficiency. Early detection of issues and quick implementation of solutions are required to keep the hedge healthy in the long term.

    

Clean tools: The key to healthy hedges

Dirty blades not only lead to unclean cuts, but also to poorly healing wounds, which are ideal entry ports for pathogens.

Regular cleaning and sharpening of the tools, on the other hand, ensure precise cuts that help plants to regenerate quickly.

“With clean and sharp tools, we not only protect our plants, but also ensure the quality of our work.”
Iain Garett, Forester at Bathurst Estate

Optimum equipment care for disease prevention

To achieve the best results and minimise the risk of disease, the professionals at Bathurst Estate do the following:

Sophisticated processes: From cutting to cleaning

Maintaining the record-breaking yew hedge requires not only skill, but also the careful use of modern tools. First, the hedge is shaped with powerful battery hedge trimmers.

The areas further up pose a particular challenge. With the help of a platform, the hedge can be worked on safely and precisely without putting the structure of it at risk. The STIHL HLA 135 battery extended hedge trimmer, with a total length of 2.49 metres, is used for cutting on the top. The cutter bar can be adjusted by 145 degrees, making it easy to adapt to the conditions.

Finally, the team uses battery leaf blowers to clear the cut branches and debris. This keeps the hedge healthy, and helps maintain its flawless appearance.
