What is the recommended pH range for the vegetable garden?

• A. 5.5-6.0
• B. 7.0-7.5
• C. 6.0-6.5
• D. 6.5-7.5

Answer: (C)

Understanding soil pH and nutrient availability is the key idea. Most vegetables grow best in slightly acidic soil, where essential nutrients are readily dissolved and taken up by roots. The recommended range of 6.0 to 6.5 is the sweet spot for a wide variety of vegetables because it provides the best balance of nutrient solubility and uptake. In soils well below this range, some nutrients become imbalanced or toxic and others are harder for plants to absorb. In soils above this range, several nutrients—especially iron and other micronutrients—become less available, leading to deficiencies. If your garden soil falls outside this range, adjust gradually with amendments (acidify with organic matter or sulfur to lower pH, or lime to raise pH) and recheck after a season.
