What is the chemical formula for Miracle-Gro?

Answer 1

You might get better blooming with osmocote, peter's, or Jacks fertilizer.

------------------------

Actually the brand is not as important as the numbers on the package. Fertilizers have three numbers printed on the package.

These numbers refer to the three nutrients that plants need in the greatest quantity. These elements are -nitrogen (N), phosphorus (P) and potassium (K).

Numbers such as 20 - 20 - 20 or 7 - 9 - 5 indicate the total percentages of N-P-K (in that order).

Nitrogen (the first number) N is important for the vegetative growth of plants. Leaf yellowing is often a sign of lack of nitrogen. Too much nitrogen can slow down the manufacture of fruit and flowers.

Phosphorus (second number) P is critical for roots, fruit and flowers. A blooming plant usually responds to extra phosphorus by displaying more flowers.

Potassium (third number) K makes the structure of the plant strong. This increases resistance to stress and disease. (Potassium is also known as potash.)

Answer 2

The current formulation of Miracle Gro All Purpose Plant food is 28-8-16. That means that it is 28% nitrogen, 8% phosphorus, and 16% Potassium. The rest is micronutrients.
