This is all very well, but what if these triffids are in your neighbour's garden and all they want is to shut themselves away and screen every glimpse of their neighbours? Ours have both the scaffolding size stem type and the clump-forming type. If you shave with a hedgetrimmer the part of the latter that invades your own side, it just encourages it to grow thicker until it takes all light off your garden, washing line etc. The other sort just grows up and up and it's stems end up like trees. A previous neighbour got rid of his 60 ft high leylandii and our veg garden breathed again, but now we have this scourge.
