Thanks for this.  However the horsetail is found in my pachysandra ground cover.   I do not want to damage that wiht the use of Glysophate.  What do you advise?

Hello Again,

For non-chemical

Then, you will have to do the by the other control method:

Mechanical or physical control methods

Mechanical or physical control methods for smaller areas of horsetail focus on trying to deplete the energy reserves of the rhizomes by removing the stems every 2 weeks during the growing season. This process can take 3 to 4 years to achieve success (Long, 2022; Burrill & Parker, 1994).
Larger areas such as crop fields can be harder to control and use of tillage equipment can actually spread the plant due to its ability to regenerate through pieces of rhizome (Cloutier & Watson, 1985). Repeated mowing or tilling could be successful if timed to target regrowth before it has had the chance to replenish energy reserves in the roots, or before it reaches 8 to 10 inches (Cloutier & Watson, 1985). Such a strategy might require multiple years of effort.


Good Luck!
