I have planted two silver birches in my front garden in sandy soil and in sunny positions. These were planted in the last six months. They have been well watered almost every day. The tree I planted first has branches dying from the bottom up. The second tree is starting to do the same. Does anyone have any ideas as to why this is happening? I live in a bayside area in Melbourne, Victoria.
Well Anne, there could be so many environmental issues that could be contributing to this problem so its difficult to diagnose accurately remotely. Best to take a cutting of the affected part of the plant to the nursery where you bought them. they will then be able to quiz you on a variety of circumstances that may give them some insights into why they are not thriving. Initially it sounds like you've done the right things by planting in lighter soil in a sunny location and keeping them watered over the warmer months.
