QUESTION: Can I fill the Treegator and then put it in place?

Do not use these handles to move the bag or to adjust the bag when it is full of water. The handles will tear off the bag if you try to pick it up when it is full.

Treegators--Great for street trees!


Treegators are the best! As a Borough Tree Commission, we started using treegators last year on our newly-planted street trees. The treegators helped us to save time on watering and they enabled us to get enough water right to the root system and water deeply which is important for young trees. They are very easy to use.

Water more with less


I live in the Texas "hill country" where in the past few years water has been an issue due to a lingering drought. As I've planted new trees I've added the gators out of convenience and necessity. Less time has to be spent watering and there is no waste. They are so simple to use and a good example of this is letting my 11 year old grandson do the watering this past weekend.

I wanted to plant some expensive oak and maple 2-inch caliper trees at my weekend place 14 miles from town. It was a challenge to be able to water the trees daily as needed. The TREEGATOR system allowed me to plant these trees with a good probability of success. Thanks for the prompt and courteous response. I will be a repeat customer. Paul B., Dalton, Georgia
