The TreeGator has been a very common sight in my hometown lately, especially during the hot summer months when rain is scarce. The Tree Gator was the original watering bag but now you’ll find a lot of generic watering bags at cheaper prices. The Tree Gator, and all tree watering bags, are highly effective for ensuring newly planted trees survive and get all the water they need. Also, during drought-like conditions, tree watering bags will keep your trees alive.
The benefits are numerous and its no surprise that Tree Gator has been hugely popular with homeowners, landscapers, and your local government. Trees are everywhere and keeping them watered can be a lot of work especially when it doesn’t rain. Climate changed has made our weather more extreme, so having your trees wrapped in a quality watering bag means you can be more hands off and allow the bag to do the work. You only need to fill it once or twice per week.
On top of that, the Tree Gator was initially designed to effectively water newly planted trees and shrubs by providing deep water saturation via slow and even water distribution directly to the root area. When using the Tree Gator you’ll find that there’s absolutely no run-off or evaporation. It’s so simple and so smart that I can’t help but wonder why more people aren’t using the Tree Gator.

Best Tree Watering Bags
We’ll get deeper into Tree Gator bags later in the article, but I just wanted to introduce you to a couple of good alternatives to Tree Gator bags. On the surface they look they same, but the differences are in the details. If money is tight, these are excellent generic tree watering bags to keep your trees healthy.

TreeGator | Simple to Use
Tree Gator is the original tree watering bag and the best tree watering bag. There have been a lot of companies creating their own version but they’re not as good, even though they might look to the same. To be honest, they’re all quite similar in function. The variation is in the materials used. These are simple products. If you want to save money then consider buying a generic version of Tree Gator.
Basic Guidelines for the Tree Gator (see the chart in this article):
- A small tree with a trunk between 1 to 2-Inches only requires one fill per week.
- A tree trunk that’s 2 to 3-Inches in diameter = 2 fills per week.
And there’s a double bag setup for larger trees:
- 4 to 5-Inches = 1 fill per week
- 5 to 8-inches = 2 fills per week
Watch this video on the Tree Gator to see how it’s set-up:
Tree Gator is the Original Tree Watering Bag
There are other watering bags on the market that look similar, or claim to work as well (or better) than a Tree Gator Slow Release Watering Bag. The truth is that TreeGator has been used by professionals worldwide since 1989. If you’re a reader of Chainsaw Journal you probably already know that the reputation and history of company and product truly do matter to me — as they should matter to you.
Great products stand the test of time, and these Tree Gator bags have done just that.

Benefits of the Tree Gator
Other than the important benefit of saving water, the Tree Gator is device designed for deep watering trees, which is also the best way to reduce the effects of transplant and heat shock in newly planted trees or shrubs.
Watering the traditional way frequently by hand or with a hose or sprinkler is an inadequate (and wasteful) method of watering your trees. Why? Because the majority of the water you use is lost by run-off or evaporation. These inefficient methods don’t allow the root zone to be saturated properly. Let’s be honest, using a hose or sprinkler is inadequate for watering trees.
In a world where drought is increasing and temperatures are generally rising, you may find yourself in a situation, such as my current situation in Vancouver, Canada, where watering is against the law for periods of time. So, instead of letting your trees die, you can wrap your trees in TreeGator’s and keep them healthy throughout Summer.
Symptoms of Heat/Drought Stress
Symptoms of drought damage to your trees can occur quickly or may happen gradually — taking up to two years to become apparent. Symptoms of drought damage will reveal itself in your tree leaves which include: Wilting, curling at the edges, and yellowing.
- Deciduous leaves may develop scorch, brown outside edges or browning between veins.
- Evergreen needles will change color, such as yellow, red or purple. The needles may also become brown at the tips and browning may progress further through the needle towards the twig.
- In a long-term drought further changes will develop. The leaves may be smaller than normal, fall prematurely or stay attached to the tree even though it’s brown.
- Don’t be fooled. Heat stress may not kill a tree outright, but it will weaken it to the point where it becomes highly susceptible to insect and diseases over the following years.
One of the initial symptoms of heat-stressed plants is the loss of turgidity which causes plants to become limp and droopy.

The Tree Gator is easy to install
Simply zip the bag(s) around the trunk of your new tree, fill it with water, and walk away! That’s it. You don’t need to dig any trenches or holes. No stakes or spikes to drive into the ground. Tree Gator saves you time, water and money.
If you live in a cold climate, you’ll need to remove your Tree Gator and empty it once the cold weather arrives. As you would expect, the TreeGator is not suited for freezing cold temperatures, so make sure you remove it from your trees before the Winter season.
After a few years of growth, young trees will have an established root system and they won’t require the tree gator any longer. Although, it’s still an excellent product to have around for times of drought and overall dry conditions.

Important Tree Watering Facts
Why is deep watering new trees important?
Newly planted trees have an inferior root system that makes the tree fragile and in need to consistently applied deep water saturation. Transplanted trees are also vulnerable due to the shock from being removed from the ground.
Deep watering with the Tree Gator keeps water and moisture levels deep below the surface where it can be readily absorbed by the tree roots. This reduces transplant shock and provides a newly planted tree the moisture it needs to grow downwards deep into the soil.
How Deep is Enough?
Experts recommend deep watering your trees to a depth at least 12″ or more. The majority of a trees root system is located within 2 to 4 feet of soil. The Tree Gator is ideal for newly planted trees because it delivers water exactly where it needs it — directly over the root mass.
Best Way to Achieve Deep Water Saturation?
The best way to ensure deep water penetration is to gradually and evenly apply a high volume of water in a single application. The Tree Gator does exactly what experts recommend and that’s why it’s such a commonly used tool for homeowners. The Tree Gator does exactly what a tree requires for healthy growth. It slowly and evenly delivers a high volume of water over an extended time period achieving deep water saturation.
Fact: Trees need a lot of water. New trees can require 10 gallons of water per week for every 1 inch of tree caliper (trunk diameter).
How much water does a new tree typically require?
While there is no standard watering amount that is suitable for all new trees, there are general watering guidelines that can be followed.
One commonly used formula suggests 10 gallons of water per week for every 1 inch of tree caliper; For example: A single 2 inch caliper (trunk diameter) tree would require approximately 20 gallons of water per week.
A Tree Gator bag will apply 15 to 50 gallons of water in a single application (depending on model and bag setup).
Why not just water frequently with a sprinkler?
Watering a tree with a sprinkler is ineffective, even on a regular basis. Unfortunately, with the sprinklers, the majority of the water applied will be lost to run-off and/or evaporation. What most people don’t realize is that light and shallow applications of water will force roots to the surface, leading to shallow rooting and poor root anchorage.
The Tree Gator actually forces the tree roots to grow deep into the ground because it delivers the water deep into the ground. It’s a simple mechanism that works. Remember, roots grow where the moisture is, so if the moisture isn’t deep in the soil then they will grow shallow, leading to weak tree.
Newly planted trees need a lot of water because they have inadequate root systems and are less effective than established trees at absorbing water.
How long can it take for a new tree to get established?
It can take several years for a transplanted tree to re-establish its root system. On average, a tree requires 1 year for every 1 inch of trunk caliper (tree diameter).
Steps to ensure your plants will reach their full potential
- Select an appropriate tree for your location. It needs to have ample room — vertically and horizontally — for the canopy and roots to grow.
- Dig a square hole no deeper than the root ball. This prevents the roots from settling too deep, allowing them to penetrate the surrounding soil.
- Fill the empty hole with water and check the drainage.
- Prune the tree sparingly, only if necessary.
- Set the tree in the hole with the root collar flush or slightly above natural grade.
- Remove all foreign materials from the root ball.
- Carefully fill the hole with the same soil that came out of the hole.
- Stake the tree only if necessary.
- Mulch around the tree at least out to the drip line, 2 to 3 inches deep and up to, but not touching the trunk.
- Wood chips, pine bark, leaf litter and hay are excellent mulches which keeps the soil temperature steady, increases soil moisture retention and prevents weeds from taking hold. Organic mulches are better as they add nutrients to the soil as they decompose.
- Water the tree for the first 1 to 2 growing seasons via a thorough soaking every 5 to 7 days using a Tree Gator Bag.
- Protect the tree from vandalism or animal damage.
- Do not fertilize the tree during the first growing season. If necessary, use tree-specific fertilizer or root stimulant. Too much nitrogen will burn fragile roots, slowing growth and delaying establishment.
