I hope you can help me.
I recieved a chinese bonsai for my 30th (2 years ago) with my same age and I really care about it.
The first year I put it right in front of the window and it was a happy tree, I was watering him 2 twince a week in summer and fertilized it once a month. Since last year it's started a strange behaviour: his green new leveas turned died after a few weeks.
I read only of the possible reasons so I:
1. moved him furter away from the window
2. Started to giving less fertilizer
3. started to filter the water from the tap
4. started to water him only once a week
but nothing, same behaviour, for the last year it started to sprout new leaves and then suddenly they died. One small little improvement happen when I started to filter the water but after 1 month it started to do the same... he regualary get attached by spider mites.
I really don't know what to do, I even called a few shops around London but they don't want to help me since I didn't buy the tree from them.
Can you please help? any recommendation will be helpful, I also attached some pictures to show the status.
Thanks a lot in advance!
