I have just been out to check on my rosemary only to find it's covered and I mean covered in mildew dust (looks like it been snowing on the four weeks) so I've sprayed them with some old bug it with mildew remover killer.
What should I do should I quarantine them away from other plants? These were cuttings taken in August?? I transplanted into deep root trainers around 6 weeks ago
