Japanese Knotweed Herbicide Treatment
Herbicide spray treatment typically has the lowest cost to you, however it can take longer to achieve control of the knotweed over using physical removal methods.
Our herbicide treatment programme consists of four applications, this can vary depending upon the plant’s uptake of the herbicide. We use SEPA & DEFRA approved herbicides applied at suitable times during the knotweed growing season (usually April to November).
Ideally preparation work is undertaken in the winter to cut, mulch & remove the dead canes and any items that might impede the new shoots in spring.
