100% cold pressed pure and natural neem oil extract sustainably sourced from the forests of India and extracted from the seed of the neem tree. Pure Neem oil freezes below 70°F. If that happens, gently thaw by placing the container in warm water prior to use. Can be used on plants in hydroponic gardens, green houses, herb gardens, container gardens and raised bed gardening. Always spot test plants prior to applying to determine plant sensitivity to spray.
