Several ends of my ficus bonsai have turned black. The other leaves look healthy. No pests noted. What is this?

If you don't see pests, it can be overwatering, underwatering, bad soil, root problems, a fungus, insufficient light, to hot, too cold, too much fertilizer, physical damage or maybe something else.

How many have black ends, compared to the rest? Are most of those black ends on the branch closest to the air conditioner? .. So many possibilities... Only if we could see it. Maybe, nothing... Do you think you could send a picture, or two?

If possible, even three:

- Close up of a leave
- Picture of the complete plant
- Picture of the pot with a good view on the soil

And also include information about:

- When you bought it
- Where you bought it
- How long you have had it
- How you take care of it (watering, feeding, position)
