F.A.Q.
Frequently Asked Questions About Deep Root Irrigation
Can I use a Root Quencher® if I don’t have a sprinkler system?
Yes. You can connect it directly to a hose bib, and timers are available for easy scheduling on IDI.
Is it possible to water too much through the Root Quencher?
Yes—like any system. Start conservatively and aim for about one full fill per cycle (≈1 gallon).
How often should I water? Will it waterlog plants?
Subsurface watering means you’ll water less frequently. Frequency depends on soil and plant type—start light and adjust as needed.
How much water do the Root Quenchers deliver?
- Root Quencher®: ~0.31 to 1.25 GPM
- Root Quencher® Jr.: ~0.31 to 1.25 GPM
- Root Quencher® Spike: ~1.875 to 3.75 GPH
What makes Root Quencher better than drip or sprinklers?
Traditional systems water from the surface, which leads to evaporation and slow absorption. Root Quencher delivers water directly to the root zone—faster, deeper, and more efficient.
How is Root Quencher different from a basic watering stake or DIY pipe?
You can DIY—but Root Quencher is designed to work reliably:
- Built-in flow control
- Adjustable depth
- Ready to install (no cutting or guesswork)
- Designed for fertilizer delivery
Won’t the Root Quencher damage existing roots if I drill a hole for installation?
We have not experienced any root damage to installs with existing trees and bushes, although you do want to be careful selecting an area to dig or drill.
Does the Root Quencher attract roots and fill up with roots and bust in a short period of time?
No, in fact after over 3 years of testing we have not seen any devices attract or fill with roots. However if roots started growing inside the device is easy to clean out. The design minimizes clogging from soil particles, and normal use hasn’t shown issues.
Can I fertilize using the Root Quencher?
Yes, the Root Quencher is designed for liquid or granular fertilizers as well as pest treatments very effectively.
Can I use granular fertilizers in the Root Quencher?
Granular fertilizers can be used in the Root Quencher, although our testing shows that liquid fertilizers are more effective.
Do I have to dilute liquid fertilizers before I pour into the Root Quencher?
No, we recommend putting straight liquid fertilizer in the chambers and allow it to mix in the Root Quencher and dispense to the roots
Can I install the Root Quencher in a drip system?
Yes. It connects easily to a ½" drip line using a barbed connector (included). You may just need a T connector and to balance water flow.
What is the difference between the Root Quencher and Rainbird’s RWS?
The RWS has several different sizes available and you have to know the soil conditions and tree needs before buying. Also there is no way to increase or decrease water volume in the RWS and no practical way to fertilize in their device. With the Root Quencher you can adjust the flow, the depth of the device and mix fertilizer in the chamber. One size fits all needs
How does the Root Quencher differ from the Tree Gator?
The Tree Gator is a bag that is placed around the tree trunk filled with water that seeps into the ground to water. The RQ waters in the ground at the roots.
Which Root Quencher should I use for shrubs?
Root Quencher Jr. is typically recommended. Spikes can also work—you’ll just use more of them.
Which Root Quencher works for potted or small plants?
Root Quencher Spike is ideal, especially for planters and vertical systems like GreenStalk.
Can Root Quencher work with systems like Rachio?
Yes. Root Quencher works with hose timers and smart systems like Rachio.
