I hope someone can help me with this. We have some specimen confiers in the garden which do not usually have any problems. But, this winter the blue-green one (my favourite) has slowly turned brown and I think has about had it now. The conifers either side are okay and look very healthy. I will need to dig the dead one out - but does anyone know what may have caused this? There is no insect damage, the soil isn't either waterlogged or too dry in that area.
All help gratefully received.
