Iron (Fe) deficiency
Eric Hanson, Horticulture
Iron chlorosis is common when soil pH is above 5.5. High pH prevents the plants from using Fe normally. Symptoms appear first at the shoot tips on young leaves. Tissue between veins is a light yellow or bronze-gold color. The leaf veins stay green. In severe cases, all leaves are affected and leaf margins turn brown and die. Shoot growth and leaf size are reduced. Symptoms are increased if soils are poorly drained or compacted.
