Spiraea - pruning
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.
