Often this plant grows out of its space and needs a good pruning. Well, this is the time to do it (i.e. late winter – early spring) before the leaves start to come out.
Spirea japonica is one of those plants you can cut back quite severely and it will flush out in new growth and look fine for the season. Flowering will not be affected either because it flowers on new growth.
How To Prune Spirea japonica
If its an older Spirea japonica you could do an overall cutting back. With this approach you can literally cut the stems to your desired size. I like to also thin the plant by pruning out some of the thicker, older stems right at the base. The plant will love the rejuvenation…and so will you.
Research Before You Prune
You can learn so much about a plant with a little research. Of course nothing substitutes for experience, but a quick “look-up” can avoid a costly mistake. In terms of pruning you should be concerned not only with how (best technique), but also when to prune. Plants are different from one another in so many ways and when you begin to understand these differences it really shows.
Everyday I see overgrown landscapes and unhealthy plants. Most of these problems could have been avoided with a little research and plant knowledge.
I’ll continue to post articles to share with you many of the experiences I’ve had (and continue to have) in my career. I really enjoy talking about it and hopefully you’ll gain some helpful tips.
