I have some Nobilis Abies procera growing for christmas trees and for foliage etc, some areas are a little off colour ‘yellowing of the inside branch’ I am guessing that Nutrient levels are low in these areas. Do you know of where I can get some tree samples tested so I can get the best fertilizer for the trees. Is there a need for a soil sample also?
