Ok So I've had my Ficus Microcarpa Retusa (Banyan Fig) for about a year. I was surprised I managed to keep it alive that long since I'm not so good with plants. It's grown a bit, shed leaves, regained them etc.
Watering and Care Routine
When it's hot I tend to water it each day or so and in winter (which we're in now) I water it once or twice a week. I touch the top of the soil and check the drainage hole to see if they're dry before watering. I don't submerge but pour water into the top. Before my spray bottle disappeared I also sprayed the leaves and trunk in summer. It sits on a window sill and gets full sun in the morning. I've tried turning it to get an even growth but it hated this so it grows on an angle towards the light.
Unfortunately I forgot about it for a week or 2 due to a hectic work schedule. When I went to water it this morning and checked the drainage hole I could see white fuzzy mould growing in the hole! There's none on the surface of the soil or trunk, only in the bottom. After researching and trying to find a cause/solution I found other threads on this forum but none seemed to fit my problem. I noticed people always asking for pics and lots of info so I've taken a range of pics including the roots. I had never taken it out of the pot so it was a very quick slip it out, photo, back in. Now that it's back in I think it might need more soil as it's sitting much lower despite all the soil being replaced. Also I think the pebbles take up too much space. When I bought it there were HEAPS of pebbles and I removed most but left some for decoration, now I think they should all be removed but then it doesn't look like there's enough in the pot. There's also no pebbles or drainage area in the bottom, just the soil then a hole.
1. What caused the mould?
2. How do I get rid of the mould?
3. Should I be repotting it?
4. If yes to repotting, how do I go about this? I have never repotted anything before.
