NPK Simplified

What is NPK?

All plants need all nutrients in various amounts, but increasing certain ones can boost a particular area of the plants physiology.  Figuring out NPK can get very mathematical and scientific but for this moment we’ll keep it simple and easy to understand. 

N is Nitrogen Feeds the “greens” of the plant and helps speed growth
P is Phosphates (Phosphorus) Promotes root and new shoot growth
K is Potassium (Potash) Promotes flowering and fruit bearing

Organic Sources of NPK

Choose a good quality fertilizer that’s intended for the type of food or flowers your are growing. I recommend using organic fertilizers, there are many good ones available such as Gaia Green or Myke Brand Mycorrhiza Growth Supplement.

I also recommend Alaska Fish Fertilizer. This liquid is filled with nutrients and very stinky so don’t get it on yourself, use gloves. The plants in the garden loves itNitrogen Phosphorus K Potassium and they will thrive with the addition of it to your feeding and watering.  

The NPK numbers on the organic products will be lower than on synthetic fertilizers. They are not weaker they just are just formulated and listed in a different way.

With a good balance of these nutrients you will set the best stage for a plant to flourish and be very healthy. 

When you are ready to dive in a learn about elements, there are six macronutrients and seven micronutrients required for complete plant health.

Don’t get confused by it all, just buy the product called “Trace Elements” and apply as directed for the plants you have. That will cover all of them and you won’t need to become a scientist to understand it all.

Trace Elements List

Nitrogen (N)
Phosphorus (P)
Potassium (K)
Calcium (Ca)
Magnesium (Mg)
Sulphur (S)

There are seven micronutrients, required in lesser amounts:

Boron (B)
Chlorine (Cl)
Copper (Cu)
Iron (Fe)
Manganese (Mn)
Molybdenum (Mo)
