How Phostrogen works
Nitrogen promotes healthy green foliage. Phosphate develops a strong and healthy root system. Potash develops abundant flowers or fruit and helps plants become more drought and disease resistant. Provides the essential trace elements needed by plants for health and vitality.
Tips
Pour any unused solution onto bare soil, not grass. Any spillage of concentrate powder onto lawns or foliage should be thoroughly watered in immediately. Stored under cool, dry conditions, this product will not deteriorate. If disposal is necessary reseal and throw away with household waste.
