This toxic perrenial, sometimes confused with marestail, is difficult to control and causes damage to hard landscaping.
Horsetail is an aggressive persistent weed which can be fully removed by physical excavation or treated with herbicides to control its spread.
Physical removal of horsetail entails the full excavation of its root system which can extend to over 2m in depth. We will excavate all the infested soil and plant material and have this sent away to a licensed landfill.
Chemical treatment needs to take place over a number of years to wear down the plant's root system. Herbicide treatment is further made difficult by the waxy coating on the plant. We mix our herbicide with an adjuvant to break down the waxy coating to increase the effectiveness of the herbicide. Treatment needs to take place over 2-3 years with two applications made each year in Spring and Summer.
