Customer feedback reports ease of use and positive experiences on lawns and container plants, including greener lawns and plants that look healthier. Other reported experiences are mixed, with some customers describing plant decline and a pungent smell. That variation matters if you plan to use it across sensitive or varied plants. The listing gives an initial dilution but does not provide a detailed plant-by-plant schedule. Overall rating data leans positive, though ratings alone do not explain individual outcomes.
