DISCUSSION: Tree Sampling for Chemical Analysis

At our recent program, “The Elements of Tree Health,” Dr. Kim Coder discussed the 20 essential elements. Often arborists in the field will sample the soil to better understand the situation, but what about sampling the tree? The sample is typically extracted from the crown, where growth is active, using either a leaf or small twig about one inch long, which is then sent to the lab. Arborists can then compare and contrast what is in the soil vs. the tree. Let us know if you have used tree sampling for chemical analysis in your work.  Click on the headline to leave a comment.

    While we use foliar analysis as a supplement, soil sampling is still our primary methodology. Samples from large mature trees are more difficult and expensive to obtain because of canopy height and leaf distribution.

    We may use foliar analysis when diagnosing smaller landscape plants – especially when we are trying to determine the cause of leaf yellowing that is not easily attributed to abiotic factors.
