Tilling/Cultural
Tilling usually involves crops. It can be
effective against rooted biennials and perennials such as diffuse
&
spotted knapweed, but sometimes small parts are left behind and
resprout. It is most effective against shallow rooted weeds. Some
noxious weeds, such as leafy spurge or Russian knapweed,
are not
effectively controlled by tillage alone because their roots are too
deep and small fragments can easily resprout. Tilling should be
completed
before
seeds develop and are shed onto the soil. The best control is achieved
when the
soil remains dry so that remaining plant fragments dry out and die.
Moist soils
help
the fragments survive and re-grow. This may take a long time because
you cannot try to water other plants because the weeds will regrow. If
tilling is your preferred choice of control the weeds must be
tilled
before flowering and replanting when using this
method or else it will not be effective. Research each weed
species before you try this method. Bibliography:
