Why Choose GallonTree
The Ultimate Slow Release Watering Bag for Professionals
Establishing newly planted trees requires consistent, deep watering. Surface watering with a hose often results in runoff and shallow root growth. The GallonTree Pro is a premium slow release watering bag engineered to deliver water directly to the root zone over 5 to 8 hours. By providing a steady drip, this young tree watering bag ensures 100% absorption, reducing transplant shock and promoting robust, drought-resistant root systems.
Built for British Weather & Repeated Use
Unlike standard seasonal bags that degrade and split, our reusable tree watering bag is manufactured from UK REACH-compliant, heavy-duty PVC. It is UV-stabilised to withstand intense summer sun and features reinforced commercial nylon zips. Whether you are managing a local authority street planting scheme or a private estate, this robust plant watering bag is designed to be deployed, emptied, and stored season after season.
Efficient Multi-Tree Care
Supplied in a convenient 12-pack, this system is the perfect solution for grounds maintenance teams and serious gardeners managing multiple trees. Simply wrap the bag around the trunk, zip it up, and fill it with a hose. For larger specimen trees, two bags can easily be zipped together to double the capacity and accommodate wider trunks. Save hours of manual watering while giving your trees exactly what they need to thrive.

Customer Reviews
Managing a large estate means watering takes up hours of my week. Bought this 12-pack and it's transformed our routine. The 5-8 hour slow release is genuine - far better than the cheaper brands that dump the water in 30 minutes.
Excellent quality heavy-duty PVC. We planted a small orchard of apple trees last autumn, and these bags have been a lifesaver during the dry spring. Delivery was incredibly fast too.
Very robust bags and the zip-together feature is brilliant for our older oaks. My only minor gripe is that you really need a long hosepipe to fill them; using watering cans for 75 litres takes ages. But the product itself is superb.
I've used Treegator before, but these GallonTree bags feel substantially thicker. The water doesn't pool around the base at all, it just slowly seeps into the soil exactly where the roots need it.
Superb value for money for professional landscapers. I leave these on newly planted street trees for local council jobs. They withstand the elements perfectly and the nylon zips don't jam with dirt.
Great slow release tree watering bag. They hold a massive amount of water. Just be careful not to drag them when they are full as they get very heavy.
As an arboriculturist, I constantly recommend deep root watering to prevent transplant shock. These bags provide the exact slow-drip irrigation required for successful establishment.
