    Frequently Asked Questions

    Most herbicide treatments are most effective between April and October when plants are actively growing. However, some species like Japanese Knotweed can be treated in autumn when herbicide is drawn into the root system.

    Many common weeds go dormant in winter, but some like chickweed, groundsel, and shepherd's purse continue to grow. Winter is an ideal time for clearing and preparing for spring treatment.

    No, avoid spraying in rain or when rain is forecast within 6 hours. Herbicides need time to be absorbed by the plant.
