The N-P-K Ratio:

For making a homemade fertilizer for your plan you need to understand what is the meaning of the N-P-K ratio. So I am here to explain to you about the ratio. 

Basically, N-P-K means the element name for the nutrients such as nitrogen Phosphorus, and potassium.


Nitrogen is an important nutrient for the growth of the stems and foliage of the plant. For a plant like a monstera or elephant ear, you need a fertilizer having a high N number then P and K in the early stage for rapid growth. 


The phosphorus is considered a healthy and important factor for the root systems and for flower production. So the fertilizer that you bring from the store has high amounts of phosphorous to promote floral displays.


Potassium helps to increase plant hardiness which provides the plant with insect and disease resistance. If the plant has potassium deficiency then it tends to grow slower and doesn’t look healthy.


Hence concluding here to follow the steps you make plant fertilizer by your own and without spending money on it.
