This formula is recommended for summer feeding of roses, geraniums and other ornamentals. Greenhouse tomatoes and cucumbers grown in soil respond well to this formula when used alone or in combination with potassium nitrate. This high potassium fertilizer is ideal for use when plants are maturing and blooming. It allows the plants to establish heavier, thick-walled cells which results in efficient water utilization. Since the potential acidity is very low, this fertilizer will exhibit minimal acidifying activity in the soil. It is particularly useful where a change in soil pH is undesirable.
