Answer: A complete fertilizer contains the three basic nutrients required for plant growth: Nitrogen, Phosphorous and Potassium. Nitrogen promotes healthy green growth; phosphorous promotes flowering and strengthens stems; potassium encourages root growth and works in conjunction with the other two nutrients. A balanced fertilizer contains equal amounts of these three minerals. An example of a balanced fertilizer is 10-10-10 or 20-20-20. Most garden plants will be happy with a balanced fertilizer but there may be times when you want to promote flowering but not too much growth. In that case you might use a 5-10-5. Other times you might want to promote green growth but not flowering. In that case you might use a 10-5-10. Hope this answers your question.
