Nature's MACE products are plant-based, with ingredients that are generally regarded as safe, per the environmental protection agency. Our products are designed to be environmentally friendly and safe, when used as directed. They should not harm or negatively affect plant life in anyway. We use the power of plants!
Do not apply the liquid products onto plants during peak sun hours. The product is more likely to evaporate and become less effective. Apply the product in the early morning and late evening when there is little sunlight shining directly on your plants. Even spraying water onto plants, during peak times with extreme heat (over 90 degrees) can cause a slight burning or browning of the leaves.
If you still worry that Nature's MACE will harm your plants, dilute the product slightly more than recommended and apply more frequently to get similar results.
