Iron Deficiency

Nutrient disorder (Fe deficiency)

A common nutrient deficiency affecting trees in alkaline or neutral soils where iron becomes insoluble and unavailable for plant uptake. Iron is essential for chlorophyll production and proper tree health.

Peak Season: Symptoms most severe during cold, wet spring weather; can persist throughout growing season
Iron deficiency symptoms showing chlorotic leaves with green veins

Identification & Symptoms

What to Look For

Young leaves uniformly yellow (chlorotic) with narrow green veins
Older basal leaves remain darker green
Leaves are small and bleached with marginal scorch
Apical and marginal leaf scorch in severe cases
Shoot length normal but small diameter
Twig dieback and defoliation in severe cases
Poor fruit coloring in fruit trees

Potential Damage

Reduced photosynthetic capacity due to chlorophyll deficiency
Stunted growth and reduced vigor
Twig dieback and branch mortality in severe cases
Increased susceptibility to other stresses and diseases
Poor fruit quality and heavy fruit drop in fruit trees
Overall decline in tree health and appearance

Lifecycle

Iron deficiency typically develops when soil conditions prevent iron uptake rather than from lack of iron in soil. Symptoms are most severe during cold, wet spring weather when root uptake is limited. The condition can persist throughout the growing season without proper treatment.

Professional Treatment Approach

1

Soil pH testing to determine alkalinity levels

2

Trunk injection with chelated iron for rapid correction

3

Soil application of iron sulfate or chelated iron

4

Improve soil drainage to enhance root function

5

Acidify soil with sulfur or organic matter where appropriate

6

Regular monitoring and annual treatment programs for chronic cases
