Q.How Much Pruning A St. John’s Wort Bush Can Take In The Summer?

Zone Santa Rosa, CA | gravenstein added on July 20, 2021 | Answered

I have a reasonably healthy St John’w wort bush that had a decent flower production this season in Northern California zone 9. It did not have a serious prune in many years, and has now grown to 6+’ hight, 6′ diameter, is woody, and dense inside. With the bush near the house and fire season around the corner I would like to significantly reduce its size and the number of stems. I was wondering how much and how far can I cut down at this time of the year (mid-summer).

I would not cut it at all at this time of year. Wait until spring. This article will help:
