Why is Arundo donax a problem?
In California, arundo infestations are particularly problematic because this weed chokes out native willows, it can provide a lot of fuel for fires which are typically very uncommon in riparian areas (arundo appears to be very well adapted to fire so fires promote arundo invasions in these sensitive habitats).
How do you take care of Arundo donax?

When was the Arundo donax introduced?
1820s
Arundo donax was introduced from the Mediterranean to California in the 1820s for roofing material and erosion control in drainage canals in the Los Angeles area (Bell 1997; Mackenzie 2004).
How do you grow Arundo donax?
Arundo donax is unable to be grown from seed, but spreads by an underground root system. As the roots spread, clones of the main plant grow along with it. The plant grows much more quickly than surrounding plants and can easily outcompete them if left to run wild. Giant reed grows best in wet soils.
Is Arundo donax invasive?
Dense stands of Arundo displace both native plants and wildlife, through monopolization of space, water, and sunlight. At least 10 protected animal species in California suffer habitat loss to Arundo. This invasive plant provides no nutritional value for wildlife or livestock, and reduces groundwater availability.
Where is the giant reed now?
Giant reed is considered indigenous to the Mediterranean Basin, but it was likely introduced to Europe from India. Giant reed grows in riparian areas, and in regions where it is invasive, it replaces native riparian trees and grasses, altering the ecology of riparian areas.

Arundo Donax Uses: Phytoremediation Phytoremediation is a procedure that uses living plants to cleanse polluted soil and groundwater. Planting Arundo Donax is a cost-effective approach of this type of soil restoration. Due to its high metabolism rate, it breaks down contamination faster than most plants.
Where did the Arundo donax come from?
Arundo donax is native to India and was introduced into the United States in the early 1800s for ornamental purposes.
Why is giant reed bad?
Once it has invaded an area, giant reed crowds out native plants, forming dense monocultures along rivers and streams. Because it transforms ecosystems, giant reed has been found to threaten those animal species that depend on the original plant life. Once giant reed has taken hold, control is difficult and costly.
How do you plant a giant cane?
Plant my giant canes Place it in a cool but well-drained soil, without excessive winter moisture as it does not support stagnant water, especially if the winter is harsh.
