Tree Health

Tree heath can be affected by many different diseases and insects most of these can relate to the condition of the soil, recently I was asked to investigate why the top of a Metasequoia glyptostroboides, Dawn Redwood was dead after taking a sample of the soil and getting it diagnosed the soil was found to be very low in pH cation balance dominated by hydrogen leading to acidity (under 5) this was allowing the tree to absorb in a high amount of aluminum which common in most soils but which is toxic to plants> the effective cation exchange capacity was also very low, this means the tree nutrient retention and holding capacity was poor. The solution is quite simple all that needs to be done is too raise the pH to above 5.5 (6.5 is best for most trees and plants) to prevent the uptake of aluminum. During the hotter drier months trees can be put under stress, stress and ill health can be seen from the colour, density and size of the trees foliage. When we walk around our gardens and we see our trees foliage exhibiting any signs of deformity or loss contact Angophora Consulting Arborist for efficient accurate diagnosis of the problem/s and solution to remedy the tree so it can be retained for many years as good healthy amenity trees providing many benefits such as shade during the hot weather. (first photo a eucalyptus in ill health second tree also with die back at top and the final tree in good health plenty of foliage with good colour and density
