Ideal Conditions for Weed Growth

How to Control Curly Dock
We have great success with using a product called Milestone to control Curly dock when it is found in native areas or pastures. Curly Dock can grow up to about 5 ft tall, so it is best controlled when it is young and actively growing. We do need native areas to be mowed to no taller than 6 inches for an application. Regular mowing can keep this weed at bay.
If any part of the root is left behind Curly Dock can produce a new plant. Luckily, the Milestone will get down to the root of the plant.
