Rosemary looking ill
Hello,
one by one the twigs (correct name?) of my potted rosemary are loosing their strong green colour and turning pale. I cut out the first of these some weeks ago and discovered this morning that there are four more. The remaining twigs look very healthy, but I fear they will turn out similar. Does anyone know what the cause might be and how to stop it? Thanks. Best Regards Gordon Filby PS I'm resident in Karlsruhe, SW Germany. It has been very hot (30- 35C) here over recent weeks. The plant is in a shady position (gets filtered late evening sun) but on the corner of the house where there might be some turbulence. It has been kept well watered. |

How big is the pot, Rosemary will grow into quite a large shrub so it could just need repotting. Mike www.british-naturism.org.uk |

Overwatering is the most likely culprit, but having it in the shade is no help. Rosemary is a true mediterranean plant and thrives in conditions of brilliant sun and fairly dry, lean soil. Note that some cultivars and forms are hardier than others. As an emergency therapy, I suggest you take the entire plant, rootball and all, out of the pot and place it on a newspaper for a day to let the soil and roots dry out somewhat. Then replace in the pot and move into a sunnier position. But don't overdo the sun until the plant returns to health: it is an invalid. Don't feed it while it is ailing. At this season, rosemary should be ripening the new growth it formed earlier in the year. -- Rodger Whitlock Victoria, British Columbia, Canada |

Does anyone know what the cause might be and how to stop it? Rosemary can be tricky sometimes. There is a fungus that rips through it very quickly. You should be able to see faint white wool in the leaf axils on dying stems. PS I'm resident in Karlsruhe, SW Germany. It has been very hot (30- 35C) here over recent weeks.

I'm not sure, but over watering might be implicated in allowing the fungi to take hold. Usually its a problem coming out of wet winters. I have never found anything effective against dying rosemary apart from pruning out all diseased wood with a huge safety margin and burning it. Regards, -- Martin Brown |

Rosemary looking ill
Hallo,
thaks to all who replied. The LCD seems to be that I have probably overfed and overwatered it and not allowed enough sun. I think the drying out and excision technique is the way I'll go. Thanks again. Gordon Filby "Michael Berridge" wrote in message ... Gordon Filby wrote in message ...
