Loss of Apical Dominance in Citrus
Citrus trees that lack apical dominance tend to grow in a more chaotic and less controlled way.
Where citrus trees lose their apical dominance and send out multiple shoots, check for boron deficiency.
Symptoms also include corkiness of leaf veins and gum spots in the albedo of the fruit and flesh near the rind.
Growers should check for deficiency using tissue analysis and apply the appropriate micronutrient fertilizer to the leaf to ensure supplies of the deficient nutrient are not limiting growth.
