Spiraea - pruning

edited September 2018 in Plants

Hello, this is my first post. I came across a Spiraea  (I think - image attached) in a very overgrown garden. There were several green stems with 4 leaf sets. Growing within the Spiraea  was Montbretia, two ferns, several Alchemilla mollis plants and weeds. I decided to cut down the Spiraea   to ground level – 3 / 4 inches, in order to separate it from the other plants and remove the weeds. Having re read some information on the web I am now not sure whether I should have cut down the Spiraea  at this time. Any help / advice greatly appreciated.

    I can see lysimachia punctata, but I can't see a spiraea.

    I don't see a Spirea either, although I couldn't have IDd the lysimachia Hosta.
    It's a plant I loathe   :(
    It's a place where beautiful isn't enough of a word....

    On the plus side, a hard cut back at this time of year won't have hurt the lysimachia.
    Spirea pruning time depends on the variety - the spring flowerers should be pruned immediately after flowering because they flower on growth made the previous summer, and the summer-flowering ones early in spring because they flower on the current year's new growth.

    Thank you JennyJ, Fairygirl and Hostafan1 for getting back to me. 
  • I chop all my Spireas back to 4-6 inches each Autumn, no problems encountered
