How to prune an early flowering shrub
1 Prune back to a healthy upward or outward-facing bud rather than an inward-facing one that will clutter the inside of the shrub as it grows.
2 I prefer to use sharp secateurs for thinner branches as they allow you to make a cleaner, more controlled cut.
3 Open up the base of the shrub by removing congesting branches. An open base lets air circulate better, leading to a healthier plant.
