Each plant type has a set root depth that represents established plant material. Root depth can be adjusted for each station as needed. For zones with a combination of deep and shallow rooted plants, use a shallow root depth value. Root depth values range from 2” to 36” and are modified in increments of 1”. If using the Automated WeatherTRAK station mode on a new landscape, you may want to lower the root depth for the first several months until the landscape is established. To encourage improved plant health and resiliency against prolonged heat spells, remember to increase the root depth when the plants are firmly rooted.
Default Root Depths for Different Plant Types
The following table identifies default root zone depths found in the controller. Your site conditions may vary depending on whether the landscape is new or established. Adjust the root zone depth for each station for the selected plant type accordingly.
Note
For shrubs in clay or clay loam soil, you may want to adjust the default setting of 12” to 6” or 8”.
To customize root depths from the default settings above, perform the following steps:
1. Press the STATIONS button. The SELECT STATION screen displays.
2. Press + or – to select the desired station.
