Understanding which Fertilizer is right for your lawn

N-P-K refers to the ratio of important elements in a fertilizer or soil amendment.

N - stands for nitrogen, which is responsible for strong stem and foliage growth.

P - is for phosphorus, which aids in healthy root growth and flower and seed production.

K - stands for potassium, which is responsible for improving overall health and disease resistance.

 

 

 

 

Nitrogen (N)


+ An established lawn needs primarily nitrogen, since it is not producing any fruit or flowers

+ Nitrogen helps make plants greener, and helps them grow faster

+ Produces lush, tender, green leaves (or grass blades)

- Lack of Nitrogen results in a yellow-green colour (chlorosis) and little or no growth

 


Phosphorus (P)

 

+ A new lawn needs more phosphorous to produce roots


+ Phosphorous is good for root growth, disease resistance, seed and fruit growth


+ Don’t use high nitrogen because the roots are not ready to handle top growth

- Lack of Phosphorus can result in slow or stunted growth and purplish discoloration on leaves



Potassium (K)

 

+ Potassium can help with increasing root growth, with drought resistance, and with disease resistance


+ Strengthens cell wall structure for strong stems

- Lack of Potassium can cause weak stems and slow growth
