Care of lemon myrtle

Care of lemon myrtle

I live in Singapore, and I just bought two lemon myrtles, which are native to Australia. Research have informed me that they are rainforest trees, which need mulching. However, none of the sites have information on how to take proper care of the plants. I've gone through about ten pages of Google. Nothing at all. So, I have some question for you guys who have/are planting this plant: 1. What type of soil mixture should I repot them into? 2. What should the frequency of watering be? 3. Any other things I should note? Thanks in advance.
Spring, please!

Spring, please!
