Fertilizing your plants is necessary for good, healthy growth, but with so many fertilizers on the market it can be pretty confusing to know which to choose. Below I have outlined the essential nutrients plants need to grow, with an overview on organic fertilizers, soil improvers, compost, mulch, manures & chemical fertilizers.
Essential plant nutrients
Every plant needs a number of essential nutrients to grow. Essential nutrients are nutrients that are required to enable a plant to complete their life cycle.
There are 13 essential nutrients, and each has its own critical function. Essential nutrients are divided into macronutrients (plants require a large amount) and micronutrients (plants require in smaller amounts). There are 3 others very important for plant growth, Carbon, Hydrogen and Oxygen, but these are not considered nutrients.
