Woodgrow offers various control treatments for Japanese Knotweed (Fallopia japonica), Giant Hogweed (Heracleum mantegazzianum) and other invasive weeds; by Stem Injection and Spraying. Most of these treatments need to be undertaken during the growing season, between April and September.


The Nomix Stem Master is the ultimate stem injection system. Based on precision medical equipment, it delivers an accurate dose of herbicide directly into the stem of the plant.

The herbicide is quickly absorbed by the plant and translocated to the roots, giving effective control of notoriously difficult weeds such as Japanese Knotweed and Giant Hogweed.

Targeted application ensures no damage to surrounding desired vegetation. In line with Best Practice, there is no spray drift or run-off, eliminating the potential for water pollution.
