My boyfriend bought this small bonsai for me and while it was a nice gesture I am a newbie to plant care. So, I thought oh no, those are hard to take care of! I read up on them so I have it outside in East facing sun. I am trying to figure out the watering. The store covered everything with both moss and rocks, so it’s difficult to feel whether the soil is dry/moist. I’ve had the plant for about 3 weeks. At first it was inside and it dropped a lot of leaves. But then I read more on bonsai liking wind and sun so it is now outside. Also, I noticed on the top this morning that one leaf is starting to turn black?! Yikes.... Please help!!! Also, the tag doesn’t say anything about species of plant.
