Basics of Murraya Hedge Roots

Murraya paniculata has taproots that support the stems. The taproot has lateral roots and lots of fine roots.

The invasiveness of the Murraya comes not from its root system, but from how easy it can propagate through its seeds. Murraya seeds are abundant and easily germinate and establish their roots under the right conditions.

The notoriety of murraya in terms of invasive roots probably came from the older varieties when it was first introduced to its non-native habitats.

How Invasive are the Roots of Murraya

Newer murraya varieties do not pose significant problems when it comes to its root systems. Dwarf murraya varieties, most especially, are suitable for home gardens as hedges and ornamental plants without any issue in relation to its roots.

In fact, Murrumbidgee Irrigation, one of the biggest private irrigation companies in Australia, classifies Murraya paniculata as “low” in invasiveness in relation to what vegetation can be planted near its irrigation pipeline and infrastructure.

The Fact Sheet on Murraya paniculata by the Institute of Food and Agricultural Science in the University of Florida states that murraya paniculata’s roots are “usually not a problem.” They even suggested that nurseries should be encouraged to grow murraya for planting such as near a patio and even under power lines.

That said, murraya paniculata can be planted close to structures such as by the walls of the house, beside fences or posts, and even close to some other plants and trees.
