Tree I.V. Injector and Cap

The injector is a 10" long hollow spike that's 1" dia. tapering down to 1/2" dia. at the point. It has an open top that mates with the reservoir with a snug, slip-on fit. Water migrates down to 22 outlet holes ranging from 4" to 9" below the surface. A 3" dia. shoulder serves as a depth stopper and also prohibits water from resurfacing along the body. Each injector comes with a snap-on cap used as a driving surface during installation and to keep debris from entering the injector when not in use. Molded from HDPE, the injector is very durable and UV resistant.

Key Benefits:

1. No run-off. Water never contacts the soil surface.
2. Deep-root watering. Promotes deeper root development.
3. Maximum flow rate. Flow is not controlled by the injector, but by the percolation rate of the soil.

Tree I.V. Reservoir

The reservoir is simply a 5-gallon pail that has been modified with a 1" diameter hole to easily mate with the top of the injector. Nothing high tech, but very beneficial.

Key Benefits:

1. One-minute fill time. Keeps your water hose free so you can water all of your trees at once.
2. Does the waiting for you. Reservoirs have been proven to be more patient than the average human.
3. Provides adequate quantity. Will completely soak the 5 cubic foot root well of most new trees.
4. Easy to add water soluble nutrients. Miracle Grow is a popular selection.
5. Easily portable. It has a handle.
6. Easily stackable. Uses minimal storage space.

How To Build a System for Your Unique Situation

You'll need one injector for each tree. Installation of the injector is easy, and only happens once. If the trees are newly planted, the injectors will push into the ground by hand. If the soil is hard, a mallet can be used for installation.

How many reservoirs you'll need is your choice. Here are some considerations:

For the quickest start-to-finish time you'll need one reservoir for each tree. At watering time simply attach all of the reservoirs, quickly fill them, then return later and remove them. Some uses leave the reservoirs attached during watering season which is another valuable time-saving option.

Leap-frogging is a method that works very well and requires fewer reservoirs. Say for example you have 9 trees and 3 reservoirs. You'll attach them, fill them, and move them to other trees as they empty. 

The root well of the tree is the area that was disturbed when the tree was planted. For the first few years, this area is more porous than the surrounding area, so it will soak water better. Placement of the injector should be centralized near the base, but if low branches make this difficult, it can be moved farther out. For best results, attempt to locate the injector within the root well area.
