Quick verdict
A 32 inch stainless probe with a T-handle, a brass hose valve and four outlet holes that pushes into the root zone and delivers water directly where tree and shrub roots feed, instead of wetting the surface where it evaporates. A fertiliser bottle attachment feeds at the same time. For establishing trees in dry weather and for deep watering in drought, it uses a fraction of the water of a sprinkler and reaches roots a sprinkler never does.
Strengths
- Delivers water straight to the root zone, not the surface
- Four outlet holes resist clogging
- Stainless tube and brass valve resist rust
- T-handle makes pushing into soil easy
- Fertiliser attachment feeds while watering
Weaknesses
- Hard, dry clay resists the probe; start with a surface soak
- The 32 inch length is more than small shrubs need
- Hose must follow you from tree to tree

Why Sprinklers Fail Trees
A lawn sprinkler wets the top few inches of soil, which tree roots mostly ignore and which dries by evening. Trees in their first years, and any tree in drought, need water in the zone a foot or two down. A deep root waterer is a hollow probe with holes near the tip that pushes into that zone and delivers water there. enomol’s version is 32 inches of stainless tube with a T-handle, a brass hose valve and four outlet holes, with a bottle fitting for liquid fertiliser.
This review is based on the listing specifications and on how deep root watering probes perform generally. We have not used this tool ourselves and the brand is a generic importer.
How It Works
Connect the hose, push the probe into the soil around the drip line of the tree and open the valve. Water flows out of the four holes near the tip into the root zone, with little running off or evaporating. Move to three or four points around the tree, a few minutes each. The holes left behind let air and the next rain reach the roots as well.
Water and Roots
Deep watering does two things. It gets water to where roots actually feed, so a stressed tree recovers; and it trains roots to grow deeper, which makes the tree far more tolerant of future drought. A tree watered at the surface grows shallow roots and suffers every dry spell. Owners report establishing trees through hot summers on a fraction of the water a sprinkler used.
Build
Stainless tube resists rust inside and out, and the brass valve is the right material for a fitting that lives wet. Four holes instead of one mean a blocked outlet does not stop the flow. The T-handle gives leverage for pushing into firm soil.
Getting It Into the Ground
In dry clay the probe will not go in by force. Open the valve to low flow and the water softens the soil ahead of the tip as you push. Never strike the handle; the tube bends. Thirty-two inches is deep enough for large trees and more than small shrubs need, so push only as far as the root zone.
Feeding
The fertiliser bottle attachment draws liquid feed into the flow, placing nutrients at root depth. Use a dilute feed; roots take up what is delivered directly far more efficiently than broadcast granules.
Who Should Buy It
- Anyone establishing new trees through their first two summers.
- Owners of mature trees in drought-prone regions.
- Gardeners feeding fruit trees and large shrubs.
Common Owner Complaints
Difficulty in dry hard ground and dragging a hose around a property. Low-flow pushing solves the first; a hose reel helps the second.
Alternatives to Consider
Tree watering bags drip slowly over hours and suit young trees in lawns. Soaker hoses coiled at the drip line water mature trees without probing. Ross root feeders are the branded equivalent of this tool.
Verdict
For getting water and feed to tree roots instead of the surface, this stainless probe does the job for years at a modest price. Use low flow to push it in, work around the drip line and your trees will show the difference by the second summer.

enomol 32 Inch Stainless Steel Deep Root Tree Watering and Feeding Stake FAQs
Surface watering wets the top few inches, which dries fast and encourages shallow roots. Delivering water 12 to 24 inches down where tree roots feed uses less water and trains roots deeper, which makes the tree more drought tolerant.
Three or four around the drip line, a few minutes each, moving the probe. Young trees need less; mature trees more.
Turn the water on at low flow as you push; the water softens the soil ahead of the tip. Never hammer the handle.
The holes left behind help air and water reach deeper and loosen compaction a little, which is a side benefit.
