Potassium (K)

Potassium is essential to all plants, but is required in larger amounts by vegetables, flowers and crop bearing trees. Potassium helps to protect plants from disease, improves colour and quality of fruits. Potassium is important to lawns, improving water resistance and increasing heat, drought and cold tolerance. Deficiency is likely to occur in very sandy soils. Symptoms first appear in older leaves which become a dull grey-green colour. Yellow spots then appear on leaf margins and tips. These spots expand causing these areas to scorch and die.
