The Plant Health Index

How can you be sure you are buying plant stock that will thrive? Wouldn’t you like to be able to reassure your clients that your landscape scheme will succeed? A visual inspection of the new trees was generally the only way to assess the health of the tree. The problem with this approach is that symptoms of ill health may not appear until it’s too late.

Enter the Plant Health Index, the new benchmark for physiological health of nursery trees. This is a rating system designed by Barcham Trees which acts as an early warning system to ensure the trees you buy are thriving.

Years of Dedicated Research

Working together, Barcham Trees and Bartlett Tree Research Laboratories have collated data over a four year period using leaf fluorescence, chlorophyll content and electrolyte leakage. Over 60,000 trees have been tested over the whole period involving some 300,000 individual leaf samples and over 300 species and cultivars.

This system can be extended into the landscape following planting allowing for an assessment of tree vitality measured against known criteria.

Keith Sacre of Barcham Trees and Glynn Percival from Bartlett Research Laboratories will deliver a joint presentation explaining why the nursery decided to invest in such extensive research, the value of such a benchmarking system to professionals involved in urban tree management and the science behind the tests used.

The presentation is part of CASTech at Capel Manor College on Friday 2nd May 2014. For more information and booking contact
