I got this bonsai for my tree fanatic boyfriend for christmas about a week ago and it's been fine until the last few days. I read that if it gets overwatered the leaves will go a yellow colour and if underwatered the leaves shrivel. But now I have a problem as I have some leaves going yellow and some shrivilling.
So what I really need to know is what type of watering it needs to be getting and how often to keep it and it's leaves healthy.
