What is an Invasive Plant?

An invasive plant is generally not native to the Sonoran Desert. These plants compete with native plants and have the ability to take over an area. Invasive plants upset the sensitive and natural ecological balance of the surrounding area and can also disrupt the habitat for desert wildlife. In addition to the impact on native plants, this vegetation becomes a major fire fuel source during the hot weather when these weeds dry out.

SO HOW DO YOU REMOVE INVASIVE PLANTS?

Stinknet/AKA Globe Chamomile – Manual removal prior to seed is the most labor-intensive method but also the most successful. Weed and Grass has shown success once the weed is visible and pre-emergent herbicide such as Milestone applied in early spring and/or fall after is effective.

Buffel Grass – String trimmer, rake and remove.

Red Brome – String trimmer, rake and remove.

Malta Starthistle – Hula Hoe or manual removal are the most effective method of removal. Root is hearty enough to grow back after treated with chemicals and herbicides.

Fiddleneck – String trimmer, hula hoe, manual removal or herbicides are effective. Fiddleneck is harmful to livestock and should be kept clear of any turnouts or livestock enclosures.

Desert Broom – Prune down to the ground, apply Round Up or similar herbicide directly to fresh pruned remains. After several months root will/should pry out of the ground.
