1 Gallon of Live Oak Leaves 100% Organic: 100% Pesticide Free, 100% Fertilizer Free, 100% Herbicide Free All leaves have been hand gathered, dried, cleaned, inspected, and heat treated to 150 degrees Fahrenheit. Can be used for all of your leaf litter, pet, reptile, vivarium, terrarium, dart frog, snake, isopod and decorating arts and craft needs. These leaves fell naturally from our healthy 80 year old mature Live Oak Trees. These trees have never been treated with pesticides, fertilizers, or herbicides of any kind in their life time. A professional arborist inspected these trees this year and all are in very healthy condition. All leaves have been dried, gently cleaned and inspected, but since they are directly from nature we cannot guarantee there will not be a tiny amount of dirt or sticks etc. from nature with the leaves. Even though leaves are organic, use leaves at your discretion, you can take extra steps and boil them if you prefer.
