Im sure this has happened before.
TJ has sided on some argument about environment impact. Then used some extreme case such as the caingorms plateau.
In reality most of us ride in the outskirts of Birmingham,London,Bristol,Manchester,Leeds etc
Im sorry but there is no way a banana plant is going out grow the native plants found in these parts.
And if its chucked in a bush no one will even see it.
I though banana trees were really difficult to grow anyhow and need to be grown from cuttings, I though the seeds stopped working once domesticated.
“Cultivated bananas are parthenocarpic, which makes them sterile and unable to produce viable seeds”
Also in most of Mid to lowland England maybe not scotland of the high peak/lakes. The banana can not possibly alter the soil to any great extent.
