Understanding the three numbers on fertilizer packages will help you make the right choice. Zach from Buchanan’s Native Plants explains.
Dany: A lot of times people go to the nursery and they’re searching for the fertilizer. And they see these three numbers 6-2-4, 8-4-6, and that stands for NPK. So what’s the N?
Zach: Nitrogen is what kind of helps plants grow. Leaves get bigger. The next one is phosphorus. Phosphorus is all about blooms. Blooming plants, you want a high middle number. High phosphorous, in theory.
Dany: Sure, sure. Then you got the K.
Zach: K is potassium. And potassium is what helps these plants consume and take in and use all these other elements that are present in excellent organic fertilizers.
Dany: So these three elements are kind of advertised to us, but plants need scores of elements. Scores of different nutrients, not just three. So even something like this has to grow, has molybdenum, and cadmium, and manganese in it. All those elements are still in this.
The idea is right, as you’re feeding this soil. And when you have a great soil, you have great plants.
