MAKING SENSE OF FERTILIZER LABELS
Nitrogen - Phosphorous - Potassium
​
Nitrogen provides the plants with the ability to produce more chlorophyll, which will help the plants to grow quickly and give them a darker green colour. It also aids in helping promote foliage growth.
Phosphorous promotes root growth and increases the ability for a plant to flower and the size of the blooms. Fertilizer with high amounts of phosphorous should be used when you are first establishing plants to your garden and sowing your lawn, either for the first time or for overseeing.
​
Potassium contributes to the overall health of the plant. It will help guard the plant against diseases, aids in cold weather tolerance and protection in droughts. Use a high-potassium fertilizer during summer when insects and diseases have caused damage to your plants and in the start of winter to prepare for drastic temperature changes.
