GRAUERHUND 20 Gallon Tree Watering Bags — 25-Pack Slow-Release PVC Bags with Heavy-Duty Zipper

GRAUERHUND’s 20-gallon slow-release tree watering bag is a heavy-duty PVC irrigation solution designed to deliver water directly to tree roots over several hours, reducing watering frequency and protecting young and established trees from drought stress.

Whether you’re planting a new sapling or maintaining mature ornamentals, these reusable watering bags provide a steady drip of water to the root zone without surface runoff. Built with reinforced PVC, an extra-large fill opening, and a heavy-duty zipper, the set of 25 bags is intended for landscapers, municipalities, nurseries, and homeowners who need a reliable, time-saving watering method.

How does this bag save time compared with traditional watering?

By releasing water slowly over 5–8 hours, each 20-gallon bag replaces multiple hand-waterings and prevents wasted runoff. You typically fill the bag once or twice a week instead of daily watering sessions, which lowers labor and water waste.

• 20 gallons per bag covers roughly one 2" caliper tree for a week
• Slow release lasts 5–8 hours per fill
• Fill fits up to a 3" diameter hose for quick refills
• Reduces overwatering and soil erosion from high-flow watering

Will these bags work for different tree sizes and species?

The bags are sized for newly planted and growing trees with trunk diameters typically from 2" to 8", and they concentrate moisture at the root ball where trees need it most. For larger trunks you can pair two bags together to increase coverage and hold more water around a wider root zone.

• Single bag recommended for 2"–4" caliper trees
• Two bags zipped together suggested for 4"–8" caliper trees
• Best when lower branches start at least 25" above ground
• Works with most species that benefit from deep, slow watering

What are the construction and durability features?

Made from reinforced PVC, these bags combine a tall, slim profile with triple-stitched lift straps and sealed edges to withstand repeated use. The heavy-duty locking zipper and large fill opening make filling and securing the bag fast and straightforward.

• Sturdy PVC material resists punctures and UV exposure
• Large fill port fits common hoses and reduces filling time
• Triple-stitched straps for safe lifting when full
• Sealed bottom edges to minimize leaks and wear

How should I install and maintain the watering bag?

Place the bag around the tree’s trunk at the root flare, fasten the zipper, and fill to capacity using a hose or bucket. Empty and store bags during freezing temperatures, inspect the zipper and seams periodically, and patch any small punctures to prolong life.

• Position at the root crown and zip closed for a snug fit
• Fill slowly to avoid pressure surges inside the bag
• Drain and store indoors in winter to prevent damage from ice
• Repair small punctures with PVC-compatible adhesive if needed

Who is this for? Landscapers, municipalities, tree care professionals, nurseries, and homeowners who want a durable, reusable way to deliver deep root watering will find value in the 25-pack GRAUERHUND 20-gallon bags. They are particularly useful for large planting projects, street-tree programs, or anyone seeking to reduce labor and water waste while helping trees establish strong root systems.
