Control
Black locust can be difficult to control. Because this species
is strongly clonal, all stems in a clone must be treated. It is
critical to monitor the site to ensure that cut and treated
stumps do not resprout—if a single stem survives, the entire
clone may regenerate.
Mechanical control
Control of established black locust populations generally
requires the use of herbicide although mechanical control
may occasionally enhance the effectiveness of other
methods.
Hand-pulling/Digging/Bull-dozing
Since most black locust spread is vegetative, and saplings
are connected underground, hand-pulling is not useful.
In general, damage to the root causes sprouting also. On
highly disturbed sites, cutting trees and removing the roots
with a bulldozer has been suggested but does not appear
practical in most settings.
Cutting/Mowing
Cutting without the use of herbicide produces prolific
sprouts and is not advised. In a comparison of cut and uncut
sites, those that had been cut had twice the growth rates of
those that had not been cut, and began to flower in half the
time |
