Learning how to take forsythia cuttings in summer is one of the easiest ways to double your shrub collection (at zero cost). While softwood cuttings can be taken in spring, when forsythias are producing plenty of fresh growth, semi-ripe cuttings can be taken anytime from midsummer, and August is a perfect time to do this.
I’ve grown forsythias for many years, annually pruning several large (and unruly) specimens grown as hedges in South Wales. And, while they do require a good trim every year after flowering to keep them compact, they are otherwise fuss-free shrubs that deliver high impact in spring. I mean, who wouldn't love that yellow pop of color early in the growing season?
