Nuisance kniphofia

I have massive clumps of rampant kniphofia. Which don't seem to flower and just leave  floppy long leaves.     Are they worth propagating ?    One rootimage has even grown through a bulb ????image


  • I think they will benefit from splitting and dividing - discarding the older plants at the centre of the clump and replanting the younger ones, well spaced, and give some fish, blood and bone.  

    That is, if you like kniphofia - if you don't I'd get rid of them and replace them with something you do like and that will add to your garden.
