When extra calcium and nitrogen may be helpful

  • Alongside a regular fertilizer that supplies little or no calcium and nitrogen
  • For plants in soilless mixes or hydroponics, where calcium and nitrogen is not supplied by the soil
  • When a soil test shows calcium and nitrogen is low
  • For crops that use a lot of calcium and nitrogen, such as tomatoes, peppers, leafy greens and fruit trees
  • During active growth, when demand for calcium and nitrogen is highest

Light, watering, roots, temperature and pH shape how a plant looks, and shortfalls of different nutrients can resemble one another, so look at the whole plant, or test the soil, before adding calcium and nitrogen.
