Looking for an efficient way to water your trees? Our 20 - gallon slow - release tree watering bag is the perfect solution. It's ideal for both newly planted and established trees. With a capacity of 20 gallons per application, it can deeply saturate the soil, promoting strong root growth and reducing transplant and drought shock. Water release times typically range from 5 to 9 hours, though this can vary based on soil, weather, and tree factors. The bag is made of weather - resistant PVC with scrim reinforcement, along with durable black polypro straps and nylon zippers, ensuring long - term use. Installation is a breeze: wrap it around the tree, zip it up, and fill it with water. You can use a 3 - inch diameter hose, and it takes only 2 - 5 minutes to fill with a standard garden hose. There's no fixed watering schedule; you can adjust it according to local conditions. This bag helps you save time, water, and money, making tree care much easier. Material: Plastic.
