Controlling Solomon Seal
I have a large patch of Solomon Seal, which has been there about 30 years. I have tried chopping bits off the edge but the roots go down a long way. They look like several layers of dense crossing giant pasta. The root mass has risen above the general soil level, and the active shoots look like they are in the top layer. Will it be sufficient to cut off the top layer? Or do I need to get the roots out right the way down ? Will it spread from any deep roots left in the soil? Once I have cut it back to size, I intend putting a barrier around to stop it escaping again, but wondering how deep I need to make it. Thanks for any advice.
