Plants require nutrients to grow and develop, much the same like people. We eat so our bodies can get the vital nutrients and minerals to grow healthy. This brings to mind the saying “you are what you eat” and it is the same with plants. Poor feeding and low nutrient levels will result in poor or diminished growth and low food, flowering and fruit production. As mentioned in our page on keeping soil healthy, we need to supplement the nutrient value of the garden soil by making soil amendments in the form of adding fertilizers, preferably organic fertilizer. These nutrients include Carbon, Nitrogen, Calcium, Hydrogen, Phosphorous, Magnesium, Oxygen, Potassium, Sulphur, Iron, Zinc, Chlorine, Manganese, Boron, Copper, and Molybdenum. Soil is the most important source of plant food.
