West Sussex, United Kingdom
I've recently planted a portugal laurel (for screening) very close to a pussy willow tree. The laurel looks very healthy but lots of leaves are turning bright yellow. Can I assume this is lack of water due to willow and give it more, despite frequent rainfall, or could it conceivably be too much? (clay soil) Other plants, eg cotoneaster cornubia and griselinia, equally close, are not displaying same symptoms. I would be grateful for any thoughts or suggestions.
