Topic: Invasive Roots

[TrailRat]

I read some where that by planting crop that has an invasive root in a pipe sunk into the ground that this contains it. Is this true? Has anyone tried it?

The reason I want to know is for my comfrey and mint, which are persisitant little "illegitament childs"

Have done it with mint, planted it in an open bottomed bucket, but be sure to leave the lip of the bucket proud of the soil, otherwise the rooting stems just run clean over the top of the pot and rampage though your garden!

This is where some knowledge of botany is useful. Mint spreads by underground stems (rhizomes), not roots. Because they are stems it is important that they remain close to the surface, so, yes, such a practice would work for them. It would only work for comfrey if the pipes go below their normal root run.

How about a two metre long clay pipe. Would that work for comfrey?

Dear TrailRat,
what is the name of the character that is posted under your name?
Is it Penfold or something from dangermouse?

Wow that music really sticks in your head!

[TrailRat]

Penfold it is. Used to be my nickname at school. Named after the road the letterbox is supposed to be on.
