Ailanthus altissima - tree-of-heaven
|
Found primarily in disturbed
areas. Due to its prolific seed production and rapid growth it
out-competes native vegetation. Also, it produces a toxin that
restricts the growth of native vegetation. Pulling before the
seedling's taproot has been developed most easily controls Ailanthus.
This means that early detection is vital. Once established, the most
effective method is cutting late in the growing season and then
applying herbicide to the cut stem. If the patch is too large to manage
by cutting, it may be more feasible to broadcast herbicide in late
summer or early autumn. The area will need to be monitored for several
years and re-sprouting of new plants controlled.
