What is complete fertilizer used for?

What you choose will depend on your soil and what you are growing. The three numbers that you see on a fertilizer label, such as 5-5-5, tell you what proportion of each macronutrient the fertilizer contains. The first number is always nitrogen (N), the second is phosphorus (P) and the third is potassium (K).
What is the best time to fertilize plants?
Generally speaking, the best time to fertilize landscape plants is
around the time they begin to grow actively
