St. John's Wort

10 years ago

We live 1 hour north of San Francisco and planted St. John's wort last spring (2012). The plants were growing well until just suddenly this week, they are yellowing and have leaf spots We have been watering them and did fertilize with Osmocote. We r beginning gardeners and hope you can advise us..soon.
Thank you.

Did the change occur after fertilizing? Maybe too strong on the fertilizer. If you feel strongly that's not it, plants might not need water as often as you've been applying.

Which St John's Wort did you plant? There are a lot of Hypericums from tiny alpines to large shrubs. It would help to know which one we are discussing. If it is H calycinum it needs no fertilizing and probably no water, especially in the winter. Got a picture if you don't know the name?
