Does a tree need vitamins and minerals?

Every living thing needs nutrients to grow and stay healthy. Trees require a combination of macro- and micronutrients, all of which they absorb from the soil. The key mineral elements for tree health are nitrogen, a key component of chlorophyll – essential for photosynthesis – phosphorus for root growth and the production of flowers, fruit and seeds and potassium for healthy fruit and protection from sickness. Other important nutrients include calcium, magnesium, sulphur, boron, iron and zinc.

Signs of mineral deficiency in trees include yellow or sparse leaves, slow growth and wilting
