Installation Guide

How to use
  1. Unfold the bag and wrap it around the base of the tree trunk, ensuring the zip is facing outward.
  2. Pull the zip up completely to secure the bag in place.
  3. Insert your hosepipe into the fill opening located near the top of the bag.
  4. Fill the bag to approximately 25% capacity, then gently lift up on the two black straps at the top to expand the bottom of the bag.
  5. Continue filling to the desired 20-gallon capacity and allow it to slowly drain over the next 5-8 hours. Refill 1-2 times per week or as needed depending on weather conditions.

Professional & Gardener 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.

Fiona Campbell, Perth

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.

Sarah Jenkins, Bristol

Founded in Yorkshire, GallonTree was born out of a frustration with thin, seasonal watering bags that split after one summer and emptied too quickly to properly hydrate deep root systems. We recognised that UK landscapers, local authorities, and estate gardeners needed a more reliable, heavy-duty solution to protect their investments in young and newly transplanted trees during increasingly dry British summers.

Our signature 20-gallon tree watering bags are manufactured from UK REACH-compliant, UV-stabilised PVC. Unlike standard consumer alternatives, our bags are engineered for a true 5 to 8-hour slow release. This precise drip rate ensures water penetrates deeply into the root zone where it is needed most, eliminating wasteful surface runoff and significantly reducing manual watering time.

Today, GallonTree is the trusted choice for multi-tree care across Britain. By offering our commercial-grade bags in convenient 12-packs, we provide a cost-effective, low-labour irrigation system that supports healthy tree establishment season after season. Whether you are maintaining a newly planted orchard, a high-street landscaping project, or a private estate, GallonTree delivers consistent, deep hydration you can rely on.
