Rowan tree
The leaves of my young rowan tree have gone brown withered and died. This
has only happened in the last few weeks. Would anyone know why this may have happened, and what are the chances of tree recovering next year. Our young ornamental cherry is started to go the same way. Thanks Mary |

Don't know, but I have a convolvulus cneorum shrub suffering the same sort
of symptoms. I dug it up tp look at the roots, nothing to see really except some white fungal discolouration on the peat that went into the hole when it was planted some time back. It's a mystery....

Thanks Mary My rowan has done the same; but I put it down to moving it last winter. Its almost certainly a root problem. The first year it was planted it went into its autumn shutdown early and then burst into leaf next spring as normal. So stay with it. Davy |

Thanks Mary What can happen is that waterlogging of the soil kills the roots, and the foliage slowly dies off due to a lack of water being provided. (This happens faster when the weather warms up and the sun comes out, because the rate of water loss from the foliage increases.) (I've lost several perennials, and I suspect shrubs as well, this year from that cause, and the same happened with the downpours of, IIRC, August 2003.) If the plant has sufficient reserves it can produce new roots, and these will support the production of new foliage, probably next year. -- Stewart Robert Hinsley |

Rowan tree
Stewart,
I think you have it exactly. My rowan is in shallow top soil over solid clay; in fact the planting hole made a depression in the clay which probably then acts as a sump. So the roots probably got waterlogged and died during the long period of rain all through recent months, and then in the two weeks of hot weather around the beginning of August the tree had insufficient roots to cope. So it appears to have gone into an early autumn shutdown but hopefully is now regrowing its roots. I assume that the roots can withstand waterlogging during the winter dormant period. So hopefully will burst into leaf again next Spring. But it seems that the tree is not in an ideal location so will always have future problems which can only get worse as the canopy gets bigger? So maybe better to replace it with something that can tolerate those conditions - such as a birch? Davy "Stewart Robert Hinsley" wrote in message ...
