• Calcium moves in the plant's transpiration stream and is deposited mainly in the older leaves.
  • Deficiencies are found in the youngest leaves and growing points, which have low rates of transpiration.
  • Emerging leaves appear scorched and distorted and may cup downwards because the leaf margins have failed to expand fully.
  • Mature and older leaves are generally unaffected.
  • With a severe deficiency, flowers can abort, and the growing point may die.
  • Fruits from calcium-deficient plants are smaller and tasteless, and may fail to develop normally at the blossom end.
