Ornamental Grasses

I have several varieties in pots.  When should I trim them and by how much?

Many have been in the same compost for years.  Should I repot and when?

  • Hi,

    I prune my ornamental grasse pretty hard in December and January.  I cut them back hard to approximately 10 cm above ground level. In my experience it promotes strong new growth. Now is a good time to lift up, if you can and divide established grass plants. They are forgiving and generally easy to grow. Good luck!

    Have to say that I am with Verdun on this one. First of all you you need to know whether they are evergreen or deciduous grasses. With evergreen types such as Festuca, Ijust comb out the dead leaves in March / April. Deciduous types do need cutting back but Winter is probably not the best time. I would leave it till March time.

    If they have been in pots a long time then they probably do need re-potting. Again I would wait till March to do this

  • Thanks to all. Apart from Tina, all seem agreed.  Wait a few months.

  • To be honest I cannot remember varieties Verdun!  Sorry.  All keep their growth and leaves all winter and the pots are on gravel.  I have one miniature bamboo, one grass stays brown and another is Elija (?) blue, others have trailing variegrated leaves.  I apologise for my lack of knowledge.

  • Thanks everyone, especially Verdun.  Doubt that my brown one is a sedge as it trails?

    Could it be Carex buchananii?

    No-one knows if you've done your housework, but everyone knows if you've done your gardening !
