⚠️ Giant Hogweed Removal
Safety-led removal of a plant whose sap burns — never strim or touch it.
About this service
Giant hogweed is a serious safety hazard, not just a garden nuisance — its watery sap is phototoxic, so any skin that touches it and is then exposed to sunlight can suffer severe burns and blistering that recur for years. Do not cut, strim or pull it. It stands 2 to 5 metres tall on thick, bristly stems blotched with purple, topped by huge umbrella-shaped flower heads, and is often confused with the far smaller common hogweed or cow parsley. We confirm the identification, then dig out the taproot and crown below ground level — work that needs no pesticide certificate and stops that year's plant regrowing — removing all cut material and seed heads as controlled waste. Where repeat foliar herbicide treatment is needed to run the seed bank down over the following two or more growing seasons, we plan and manage the programme and a qualified, certificated spraying contractor we work with carries out the application.

Questions
How do I tell giant hogweed from common hogweed or cow parsley?
Giant hogweed is huge — 2 to 5 metres tall — with thick, bristly, hollow stems clearly blotched and streaked with purple, and flat white umbrella-shaped flower heads up to 80cm across. Common hogweed and cow parsley are usually under 2 metres, with slimmer green stems and much smaller flower heads.
What happens if the sap touches my skin?
The sap is phototoxic. On skin that is then exposed to sunlight it causes painful burns and blistering, and the affected skin can stay sensitive to light for years. Wash it off with soap and water, keep the area out of sunlight, and seek medical advice if the skin reacts.
Why must I not strim or cut it myself?
Strimming flings sap in a fine mist over your skin, face and eyes and is the most dangerous thing you can do with this plant. Even hand-cutting exposes you to the sap. It should only be handled with full protective equipment.
What does the law say about giant hogweed?
It is one of the species listed under section 14 of the Wildlife and Countryside Act 1981, so it is an offence to plant it or cause it to grow in the wild. Cut material and soil containing its seed are classed as controlled waste and must be disposed of at a licensed site.
How long does it take to clear?
It is a multi-season job. Digging out the crown stops that year's growth, and repeat herbicide treatment over the following two or more seasons runs the seed bank down. Seeds can stay viable in the soil for several years, so monitoring continues after the visible plants are gone.
Do you spray the herbicide yourselves?
The physical work — digging out the crown and taproot and removing the plant as controlled waste — we carry out ourselves, and for many gardens that plus follow-up monitoring is enough. Applying professional herbicide as a paid service in the UK requires a recognised pesticide certificate of competence (commonly PA1 and PA6), so where a herbicide programme is needed the application is carried out by a qualified, certificated contractor we work with, to a plan we write and manage.
What does giant hogweed removal cost?
It depends on the size of the stand, how difficult and steep the ground is, and how many treatment visits the site needs across the season. We quote after a site visit.
