The 20 Gal. Tree Watering Bag Ring 4-Pack is a durable, refillable drip irrigation system built to keep newly planted and established trees healthy with minimal effort. Each ring holds up to 20 gal. (75.7 L) of water and releases it slowly over 6 to 9 hours, delivering deep, rain-like hydration directly to the root zone. This soak-style watering encourages stronger root development and helps trees establish faster, even in hot or dry climates. Constructed from heavy-duty 520 gsm PVC with reinforced seams, these watering rings resist tears, punctures, and UV damage, so they hold up through seasons of outdoor use. Each ring fits trunks up to 5.51 in. in diameter, and two rings can be zipped together for larger trees, making the set versatile enough for residential yards, orchards, municipal landscapes, and reforestation projects. The 1.18 in. threaded inlet cap connects directly to standard garden hoses up to 1 in. diameter for fast, mess-free filling, while the slow-release drip valve outlet provides clog-free, even distribution. Dual carry handles make the rings easy to position around the tree base, and the bags deflate flat for compact off-season storage. Reusable, water-saving, and simple to maintain, this 4-pack is a smart choice for homeowners, landscapers, and property managers who want consistent tree hydration without the time and waste of manual watering.
