每日吃瓜

Hi, Im new here, i recently received an early Christmas present which is my bonsai tree.
Im pretty sure it a Chinese privet, I've been told by a few garden centres!

Ive read different things on the internet, some saying they're hardy, others saying not too much!

Im just looking for some advice on how to properly care for it?

Temperatures? Watering? Fertilising? The right soil/drainage?

Ive noticed since getting it its dropped a few leaves, it wont let me add any more photos on here because I cant change them to jpegs?

Thankyou in advance
