What 4-4-4 Fertilizer Means
When I look for a balanced fertilizer, 4-4-4 is one of the first options I consider. The three numbers tell me the product contains equal parts nitrogen, phosphorus, and potassium.

What to Look for in Quality
For me, a good 4-4-4 fertilizer should be easy to apply, clearly labeled, and made by a trusted brand.
