I'm in southern Ontario Canada. I have an empty undeveloped area behind my yard. My grass just ends directly into this rough. It gets full of Field Horsetail as far as i can tell. These slowly creep into the grass and even pop up a few meters further inwards (dangerously close to my garden) from their underground roots. Is there any way to control this? I hope that their mere presence within the boundaries of my property doesn't mean i've already lost the battle.
Here's what google brings up.
Also, is there something i can do within the rough area to help. Maybe spreading some herbicide into the first meter of the rough area to tyr to create a small break between it and my lawn? Last year when i dug out my garden i placed all the sod that i removed along the back of my lawn into the field. I essentially plunked down about a meter of sod on top of all the weeds in the hope it would smother them. They just started growing through it.
Any thoughts appreciated.
