What are the key roles of NPK in fertilizer?

​

Nitrogen (N) – Nitrogen is largely responsible for the growth of leaves on the plant.

 

Phosphorus (P) – Phosphorus is largely responsible for root growth and flower and fruit development.

​

Potassium (K) – Potassium is a nutrient that helps the overall functions of the plant perform correctly.

​

The perfect NPK fertilizer ratio is 20 - 20 - 40

​

Most fertilizers are 20 - 20 - 20

To make the perfect 20 - 20 - 40 ratio, you must add an extra 20 of Potassium (K)

 

SOLUTION: Buy a fertilizer with only Potassium (K).

0 - 0 - 20

Add that to your 20 - 20 - 20 NPK fertilizer

​

It will be transformed into 20 - 20 - 40

​

additionally you can add some epsom salt and some minerals

​

Perfect!
