Golden Bamboo Phyllostachys aurea (Carr)Poaceae
Biology • Native to southeast China • Introduced for the landscape • Visual and noise barriers • One of the most common bamboos in U.S. • Category II invasive by FLEPPC
Distribution & Impacts • Commonly found from Maryland to Florida, far west as Arkansas • Isolated infestations in Oregon • Fast growth and spread, mainly through rhizomes, quickly displaces native vegetation • Best in full sun but also in open forests
Mature Plant • Can grow up to 30 feet in height • Green to yellow stems, swollen internodes at base • Rhizomes arise from side shoots
Leaves • Leaves are lanceolate • Roughly 15 cm long • 1 to 2 cm wide • Flowers infrequently, may be several decades before flowering occurs
Management Preventative Cultural Mechanical Biological Chemical
Preventative • Limit planting as an ornamental • Remove existing plants, including resprouts and before seeds are produced • Avoid mechanical disturbance in forested areas – logging, rouging, etc. where golden bamboo fern is present
Cultural • Alternative landscape plants to replace golden bamboo • Programs to educate homeowners about the problems associated with this plant and proper identification • Maintain good ground cover and mixture of plant species to reduce establishment
Biological • There are no known biological control agents available for golden bamboo management in Florida or the southeastern U.S.
Mechanical • Hand pull young plants, including all rhizomes, repeated pulling for resprouts • Mowing or cutting is effective, but must be repeated to control resprouts • Tillage, although likely impractical, will be very effective
Chemical - Foliar • Over-the-top applications of glyphosate at 2 to 3% solution plus 0.5% surfactant • Thoroughly wet leaves and stems with herbicide • Retreatment will be necessary for complete eradication
Chemical - Wipe • Cut stems and allow for 2 to 4 feet of regrowth • Apply (wipe) 100% glyphosate along the entire stem – use heavy cloth and rubber gloves • Will likely require retreatment
Chemical – Cut Stump • Individual trees, near desirable species • Cut trunks/stems horizonally at or near ground level • Apply 25% solution of glyphosate • Cover the outer 20% of the stump • Marker (blue) dye is helpful
