1 Melia azedarach (L.) Meliaceae
Chinaberry Melia azedarach (L.) Meliaceae

2 Biology Small to medium tree 20 to 50 feet tall Native to Asia
Introduced to U.S. in 1700’s Member of the mahogany family

3 Background Economic Uses Introduced to U.S. for fuel wood
Ornamental for flowers, foliage and shade

4 Distribution Found throughout much of southeastern U.S., Central America, Virgin Islands and Puerto Rico From Virginia to Texas Mainly found in north and central Florida

5 Chinaberry Distribution in Florida

6 Impacts Category II invasive species (FLEPPC)
Limited spread into undisturbed sites Forms dense thickets, displacing native vegetation Multiple shoots form when cut back, responds favorably to fire Prolific seed production

7 Identification

8 Mature Plant Deciduous tree Up to 50 feet tall
Reddish to purplish bark May have multiple branches Soft wood

9 Leaves Alternately arranged Bipinnate compound
Leaflets have serrated edges and 1 to 3 inches long

10 Flowers & Fruit Flowers in spring Long, fragrant, purple
Fruits are yellow, hang on tree after frost Mucilaginous/sticky Seed round, hard, marble-like and poisonous

11 Management Preventative Cultural Mechanical Biological Chemical

12 Preventative Limit planting as an ornamental
Remove existing plants, including resprouts and before seeds are produced Avoid use of possibly contaminated mulch with chinaberry seeds Prevent seed spread and dispersal Rouge out trees in abandoned areas

13 Cultural Alternative plants to replace chinaberry
Programs to educate ranchers about the problems associated with this plant and proper identification Maintain good ground cover and mixture of plant species to reduce establishment

14 Biological There are no known biological control agents available for chinaberry management in Florida or the southeastern U.S.

15 Mechanical Hand pull young seedlings, including all roots, repeated pulling for resprouts Cut tree down at ground level Girdling is effective for large trees Cut through bark approximately 6 inches above the ground, encircling tree base Mowing is effective on small saplings and resprouts, but must be repeated

16 Chemical - Foliar Over-the-top applications for seedlings, resprouts and small trees Thoroughly wet leaves with herbicide Triclopyr – 2% solution Glyphosate – 2 to 3% solution Use surfactant at 0.25% Best results applied July to October

17 Chemical - Basal Individual trees, near desirable species
Use 25% triclopyr solution with basal oil Apply 12 to 15 inches above ground on tree trunk Wet thoroughly for good control, spray until run-off is noticeable at ground line

18 Chemical – Cut Stump Individual trees, near desirable species
Cut trunks/stems horizonally at or near ground level Apply 25% solution of glyphosate or triclopyr Cover the outer 20% of the stump Marker (blue) dye is helpful
