Raspberries - Chlorosis

Symptoms
Interveinal yellowing and subsequent leaf scorch starting from mature leaves. Severely stunted growth.

Reasons
Potassium deficiency Raspberries have a relatively high demand of Potassium. An imbalanced nutrient supply with K, Mg and Ca may induce K deficiency. Its availibility can be restricted in clay soils. The suggested K level in leaf tissue is 1.5-3.0%.

Potassium deficiency made worse by

  • Acidic soils (low pH)
  • Sandy or light soils (leaching)
  • Drought conditions
  • High rainfall (leaching)
  • or heavy irrigation
  • Heavy clay (illite) soils
  • Soils with low K reserves
  • Magnesium rich soils

Potassium is important for

  • Healthy green foliage
  • Important for fruit size, development and yield
  • Reduction of fungal diseases
  • Improved sugar content of berries
  • Improved maturation of berries
