Trimming Griselinia

Hi

I was planning on trimming this grisellina back to the second rung of the metal fence to try to get some of the plants to thicken out a bit towards the bottom. Would this be a good idea as opposed to just levelling out the top? And should I do this now or wait until early spring next year? Thanks

    I would just selectively prune some of the lower branches BELOW the space you want to fill, so they will divide and branch out there.  It will create holes for a bit until it fills back in, but it should make it denser down there.  Maybe prune the top just below the top rung, to help that bush out a bit more and it should also cause the plant to put more growth hormones to all tips.  Probably best to wait until fall to prune, unless a wiser person comes along and can correct me.

    Griselinia shoots out very readily when hard pruned so I personally would not be afraid to cut it down by half.Somewhere between the first and second rung from the bottom of your fence.Shoots produced then are quite often right at the base.
    Also I prune at any time of the year to keep it in check.
    I know I have to cut great chunks off mine before it grows into a tree!

    Wherever you cut, it will sprout. If you just trim the top, it will sprout from there. If you want it thicker lower down, trim the side branches where you want them to sprout. Our hedge grows like mad and happy to be pruned during the summer.
  • Thanks all I'll give it a good trim all over and see how it goes.

    This is part of our Griselinia hedge. It’s been in place for a few years, we’ve just taken about a foot off the top, and took some long bits off the sides about a month ago. It looked a little scraggy for a week or so, but seems to have sprung back very quickly and looking lush and green again. We’ve been very pleased we planted them.

    I find that if you just keep trimming the tops and sides you gat a lot of twiggy growth there,so from time to time I get right inside and take out whole branches very low down.This encourages more shoots from the bottom and opens up the inside a bit.
