My girlfriend received a silver birch sappling as a present at Christmas as a memorial for a dead relative. A month ago we repotted it into a large pot. We placed broken tiles in the base for drainage and filled it with general compost and a small amount of cremated ashes. We have kept it inside until the weather gets warmer and it is currently placed in an east facing window (Nowhere in our house gets consistent sunlight throughout the day).
The sappling has looked like it was struggling - leaves wilting and the leaves turning yellow along the edges. We have done two things to "help":
- We made a sugar solution on the recommendation of a Tree Surgeon friend and watered the sappling with this.
- One morning my girlfriend "deadheaded" the sappling - basically taking all the worst looking leaves off (I thought that this was only done for dead flowers) - the sappling now only has a single leaf.
Any advice would be appreciated. Should we move the sappling outside? (Current temperatures are in the range 17-22 celsius). Is there anything else we can do to help the sappling?
