How it Works
3-Steps: Push Injector In... Set Reservoir On... and Fill

A newly planted tree has an undersized root ball instead of the more natural sprawling root system. Frequent watering is needed until the root system catches-up with the top side.
Your options for watering include: 1) slow-running hose, 2) tall water bags, 3) low water bags, 4) hose-fed root feeder, and now 5) Tree I-V self-contained root feeder. Read on to learn how Tree I-V systems get the best results as a hybrid combination of the other options.
Tree I-V will...
Install and fill in seconds. For recently planted trees, hand-push the injector into the root-well, remove the cap, set the reservoir, and fill. That's it! No timers, no run-off, no guesswork, and no waiting around as with hose methods. No awkward setup and heavy lifting / adjusting large bags while they fill.
Drain at a natural percolation rate. Normal topsoil should drain in 15 minutes. This is the same time required for hose methods, but now you can water everything at once! While bags must drip slowly to avoid surface run-off, Tree I-V water never touches the surface. As they empty, reservoirs can be easily removed, stacked, and stored, or moved to other trees with installed injectors. Hear that? A reservoir can easily be moved to another tree if saving money is more important than saving time.
Not harm your tree. Tall bags need a tree for support which can be fatal to small trees. The close proximity can foster insects and trunk disease on any tree. Tree I-V stands alone!
Water the drip zone for larger trees. To encourage sprawling roots, we must move supplemental watering farther out. This is not possible with any bag, but is with Tree I-V.

A process easy for anyone
Fill buckets once a week and you're done. Kids, neighbors, grandma, circus monkey... Anyone! You may also appreciate
- Independent trees faster
- Reduced water requirement
- Sustainability
Independent trees is the goal, and the quickest way to achieve it: Soak - Deplete - Repeat. When the root-well is soaked, the entire root system can feed. Nutrients are transferred up while moisture is in good supply, but as moisture depletes, the roots will shift focus to self-development. Just as plant leaves grow toward the sun, roots grow toward moisture. This is why deep watering encourages deep roots.

Conversely, constant drip irrigation in a small area around the trunk encourages top side growth with limited feeder roots. This tree may never be ready for life without help. Shallow surface watering encourages shallow feeder roots that won't do well in the next drought either.

Water Efficiency. 5 gallons will completely soak 5 cubic feet of soil. That's approximately the size of the root-well of a small tree.
While it is possible to soak the root-well from the surface, the top layer of soil and mulch must become soaked before the bottom can be. This can require 2 - 3 times as much water to be sure of a good, deep soak. Additionally, surface watering methods encourage surface roots which will even grow right up into the mulch pile. Yikes!
Sustainability. Bag watering products can be destroyed instantly with string trimmers, lawn mowers, animals, and vandals. Plastic buckets are tough and long-lasting. Made from the same HDPE, Tree I-V Root Seekers are also very tough. In fact, we are still servicing some systems from as long ago as 20 years.
