Ailing Rosemary Officianis
I have a rosemary officianalis that is growing in a large clay pot on the patio. Last year it was fine - quite happy in fact. It's around 12" across by perhaps 18" high. However, a few of the stems have died off this lately, and the remaininng ones are not looking too happy - the leaves become mottled with yellow patches, which turn brown and eventually die off. Any ideas, thoughts, suggestions? Repot? Feed? Just lacking water? I'm not entirely sure how to start reviving it.... thanks Richard -- Richard Sampson can be found at olifant with the co uk thing. |

If so, I am afraid that you can't do much for it, but make sure that the compost or soil is very free draining next time. Hmmm, possibly not what I was hoping to find out, but thanks! What I may do in that case is to cut out the dead, repot in very free-draining compost and see what happens. I didn't think that it would have been waterlogged - there was plenty of crock in the bottom of the pot, but perhaps next time I may put crock then some pea-shingle and then compost. Anyway, thanks for the replies. cheers Richard |

Mike that surprises me. When I lived in Lincolnshire I had a lovely rosemary hedge. It needed to be chopped once a year and then proceeded to bush up beautifully. I have lost my rosemary every winter in Scotland and this year I overwintered it in the cold frame in a pot. Some bits are brown but the rest looks ok Ophelia |

There is something else fungal? that invariably gets rosemary here. It attacks from the other end. The die back starts at the growing points at the end of winter (ie now) and leaves die quickly to brown. Leaf nodes show white mould back down the stem. Sometimes it isn't fatal if you cut off the affected parts but it is very destructive. It is worth watching out for - unchecked it will kill the entire plant. It was a very cold winter over here so it may have been weakened by the cold. And it has been relatively dry recently so waterlogging isn't likely to be the cause of this particular malaise.

When you repot, knock as much soil off the roots as you can, and cut the plant back -- not *too* hard, but somewhat. Or maybe "rather a lot".

I didn't think that it would have been waterlogged - there was plenty of crock in the bottom of the pot, but perhaps next time I may put crock then some pea-shingle and then compost. Crocking is no substitute for having a properly free-draining compost in the pot. Horticultural perlite might be a good choice to open up a dense, airless compost -- I'm using it these days to get more open and airier composts. If your pot sits on a hard surface, it's especially important that the compost be free-draining because there's no soil underneath to wick away excess moisture. I've never seen mention of this detail, but too many times I've looked into my coldframes (on a concrete slab) and seen a thick layer of soaking wet silt underneath the pots. -- Rodger Whitlock Victoria, British Columbia, Canada |

Thanks Rodger, bag of perlite probably a useful acquisition. From what others have said, they're happy in relatively poor compost. Any recommendations for mixes? cheers Richard -- Richard Sampson email me at richard at olifant d-ot co do-t uk |

Being old-fashioned, I would use about 3/4 pea gravel, horticultural grit or coarse sand (e.g. builder's sharp sand - dirt cheap) and the remainder a general-purpose, potting compost. I make my own, but my garden has good soil for that purpose, which helps. But any such mixture should work. Don't be afraid to include mostly 'filling', such as sand or perlite.

Mine just go from strength to strength, even though the soil is heavyish and they don't get as much sun as I think they should. I suspect that they enjoy the dry summers we have here. That they are planted at the foot of the house wall, just above the perimeter drain and beneath the overhang of the eaves, may have quite a bit to do with their success. Among the hardiest is the "pine-scented" rosemary, possibly cv. 'Angustifolia'. -- Rodger Whitlock Victoria, British Columbia, Canada |
