Tree I.V. can be filled by a 2-year-old - Bags must be held up and adjusted while filling
Tree I.V. can be located at the drip line of larger trees - Bags must be used at the trunk
Tree I.V. is very durable - Bags are easily damaged by trimmers, mowers, and vandals
Tree I.V. "Fill-n-Haul" feature for remote trees - Bags must be filled on site
Tree I.V. is right-sized for small trees - 20 gallons is overkill
Versus Hose-Fed Root Feeders...
Tree I.V. can be filled by a 2-year-old - Hose feeders must be installed each time used
Tree I.V. requires no waiting or timing - Hose feeders must be monitored and moved
Tree I.V. waters dozens of trees at once - Hose feeders are one-at-a-time
Tree I.V. "Fill-n-Haul" feature for remote trees - Hose feeders have no solution
Tree I.V. is right-sized for small trees - You NEVER know the volume with hose feeders
Tree I.V. Theory of Operation
The root well of a tree is the area that was excavated when the tree was planted. Containing both the root ball and a backfill of soil, this will be the first destination of new root growth. Small trees that have been hand planted will usually have a root well of 5 to 6 cubic feet. This area needs a good soaking on a weekly basis.
Using a general rule that says a gallon of water soaks a cubic foot of soil, 5 to 6 gallons of water is adequate. This assumes a regular watering schedule, and that ALL of the water reaches the root well.
The Tree I.V. design offers this important efficiency, with a convenient 5-gal container that eliminates the guesswork. One Tree I.V. will work for a small tree. For larger trees, you may consider three units placed equally around the drip line. It's simple. It works.
Tree I.V. Design
Tree I.V. Injector
The injector is like a straw that connects the reservoir to the ground. The outlet holes are large and plentiful so clogging is not a problem. Total depth is 9" with holes ranging from 3" to 8" below the shoulder.
The 3" shoulder is a depth limiter, but it also provides a ground seal that keeps water from resurfacing. The tapered body allows for easy installation anytime, and the blunt tip helps prevent root damage.
Included with each injector is a snap-on cap. It keeps debris from entering the injector when not in use, and serves as an impact surface during installation.
The injector is extremely durable. The wall thicknesses are 1/8" and the material is UV resistant HDPE.
Key Benefits:
No run-off. Water never contacts the soil surface.
Maximum flow rate. Flow is not controlled by the injector, but by the percolation rate of the soil.
Tree I.V. Reservoir
With a 5-gallon capacity, the reservoir holds enough water to saturate the root well of small trees and shrubs. The large open top makes it easy to fill, and easy to add nutrients or soil amendments. The injector mating point is located close to the side of the reservoir so the injector can be closer to the tree, and to make connecting and disconnecting easier.
The design of the mating point includes a durable rubber grommet. The grommet and injector are properly sized to provide a good seal while remaining easy to slide on and off. Please note: Minimal leakage is still possible at mating location.
Optional features include a hole plug and a lid. Used for transporting water to remotely located trees, the plug will close the hole and the lid will stop water from splashing out the top. Lids can also be used to keep debris out.
Like the injector, the reservoir is durable and UV resistant HDPE. The rubber grommet is durable as well, but can be replaced in the event of failure or loss.
Be sure to carefully line up mating parts. Misalignment can push the grommet out of the hole.
Key Benefits:
One-minute fill. Saves your time.
Self-regulating. Your presence is not required.
Conserves water. Efficiently uses every drop, requiring much less from the hose.
Fertilizing easy. Add liquid nutrients and soil amendments during a normal watering
Portable. Quickly connects and disconnects.
Optional plug and lid for transporting full reservoirs to remotely located trees.
Easily stackable. Uses minimal storage space.
Build Your Own Reservoir
Revised 7/24/2011 for new larger grommet
If you already have a supply of 5-gallon buckets, a drill, and a 1.375" hole cutting bit, you can easily create your own Tree I.V. Reservoir. We offer a Build Your Own System kit that includes a Rubber Grommet and a Tree I.V. Injector.
Turn your bucket upside down
Index the bucket so the handle connections are on the sides (handle is facing you)
Measure and mark a spot on the bottom of the bucket that is 1" from the bottom lip
Carefully drill a 1.375" hole. The best is a $75 Unibit, a $15 Forstner bit works well, and with great care, a $2 paddle bit will work.
