Hi all, my name is Karen and I recently planted a new garden with roll out lawn and around the same time a Swedish Birch Tree which was approx 90% still dormant. I have been watering heavily since lawn and tree have been planted and everything is thriving beautifully until today I noticed my now fully leafed up tree is browing from the bottom up. I am sure it is not under-watering, so could I be over-watering. Is this a symptom ? I used blood and bone when first planted and it boomed and is in full bloom. Why is it suddenly now browning off ? I do not want to lose her, please help ???
