Narva Authorities Remind Landowners to Combat Hogweed
The Narva City Government's Department of Urban Economy reminds residents that now is the best time to destroy hogweed before its seeds ripen, emphasizing it is the landowner's responsibility.
The Department of Urban Economy of the Narva City Government has reminded that now is the most suitable time to combat hogweed. The authorities stated on the city's official social media page that the plant's seeds are beginning to ripen, and timely measures can significantly limit its further spread.
Hogweed is an invasive alien species that spreads rapidly and poses a danger to both nature and human health. The plant's sap contains substances that cause severe skin burns when exposed to sunlight. Therefore, the department emphasized that hogweed control must be carried out with extreme caution and using appropriate personal protective equipment.
Since 2006, the Estonian Environmental Department has been running a nationwide hogweed control program. Work is carried out through state procurement, with the main methods being digging up plants with their root systems and applying herbicides. In 2026, there are also areas in Narva where hogweed eradication will be organized by the Environmental Department.
In addition to the state program, the Narva Department of Urban Economy organizes hogweed control on municipal lands. If residents discover hogweed on municipal land, they are asked to report it by email to linnamajandus@narva.ee, attaching a map fragment or a precise description of the location.
The city authorities also provided advice on how to best combat hogweed: young plants (1-2 years old) are much easier and more effective to destroy than large flowering specimens. The most effective method is digging—the root crown must be cut or dug out at least 10 cm deep to prevent regrowth. Hogweed should be removed before flowering. For large or extensive infestations, herbicides may be used, strictly following the instructions and environmental and safety requirements. During work, personal protective equipment such as long-sleeved clothing, gloves, and goggles must be used. Additionally, the area should be checked regularly every few weeks throughout the summer, as new plants may appear throughout the growing season.
