Can you control root systems of "invasive" plants by planting in containers such as mint, campanula, yarrow

Yes,it's quite common to plant herbs in containers.Dependant on the area and the amount involved,anything from a bottomless bucket to a tin bath with holes for drainage will suit.


Sunk into the soil,with an inch or so proud of the surface,plants will be kept in check.

I think your question was about root growth.... Almost any container will breakdown while surrounded by warm, damp earth. Roots will spread as the container disintegrates. I live in the south where everybody grows mint and the plants get large. But it doesn't climbs over trees and smoother everything in its way. It dies back in the fall/winter. A nursery should be able to tell you if campanula and yarrow do the same. Just don't plant kudzu.


Note: If you use a container that does not breakdown, like stainless steel or some kinds of resin, the plant will die as all its energy goes to the expand the roots instead of leaf/flower.
Reply:If they are deep enough in the ground you will probably be OK.


I used a tire once and the roots of a mint went under the tire.
Reply:You can try... I've had luck NO luck containing my mint that way, it just climbs up over the pot and out. The yarrow is no problem though...
