These pernicious weeds can be very difficult to eradicate once they have taken hold, as they have long undergroundand any piece left in the soil rapidly produces a new plant. The trailing wind themselves round other plants, often climbing to considerable heights. There are white and pink forms. Cutting off the tops or even down to soil level are useless as methods of control as the weed will simply reappear and probably with renewed vigour. Track the growths to their source below the ground. Sodium chlorate, MCPA and 2,4-D weedkillers will usually ultimately clear bindweed but repeated applications will be needed.
