How to get rid of:
Hand pulling needs to be done carefully to ensure there is a
minimum of soil disturbance. Many weeds flourish when soil is
disturbed.
Removal of small weeds can be achieved by placing one hand flat
on the ground with the weed between two fingers. As the hand is
pressed toward the ground the second hand can carefully remove
the weed.
