Dont use blinds or shades. It’s likely dropping leavings because youre starving it of light.

I grown might outdoors full direct sun all summer. These like all the light you can give them.

Ficus benjamina also doesn't like drafts.

Try the house plant forum for more accurate information.

This is in the houseplanr forum. Remember, when people post, they can choose to have it posted in up to 3 seperate forums.

In the UK at least, Ficus Benj tend to lose a proportion of their leaves at this time of year as they adapt to the lower light. In my experience they always lose up to 10% of their leaves over a couple of months when you buy them/move them as they don't like change.

So it could be that initial adaptation leaf loss has segued elegantly into autumn leaf loss. I may be shouted down at this point, but my employees are trained to continue to feed them at a very low level throughout winter as this seems to minimise leaf loss.

You know you are in trouble though if it continues in to spring :-D

@Dave, thank you. Today I opened the blinds. will see whether it's getting better. what I learned from google was they like bright but indirect light but now it's winter so it's not that strong anyway.

@Esther, thank you as well. No it's not close to the vent so that shouldn't be an issue. but the winter indoor humidity is somehow low so maybe that's part of the reason.

@Stewartsjon, it could be. I see there are still some green beads in the pot soil so I presume that they're slow releasing fertilizer?

thank you! will see what happens in the next few weeks.

Dropping still-green leaves in response to changes in environmental conditions is typical of this plant. Otherwise be sure to keep the saucer dumped out, not leave yours sitting in water for extended periods. This should be done with all potted plants.

As Dave says, you can't give these too much light.

Hi guys, I think I found out what happened. It's got scale infection. on the back of the leaves and twigs there are quite some scales. I tried to clean them up as much as possible but given that are so many leaves and tiny branches, it's hard to get rid of everything. I also sprayed some insecticide and checking it every another day.

I had the same issue on the fiddle leaf fig before (before getting it) and fortunately all it had were some big leaves so it wasn't too difficult to check every single one.

I'm now moving the benjamina ficus away from my fiddle leaf fig so hopefully the scale doesn't spread.

What's the best way to eradicate it?

Many thanks~~

A systematic insecticide works well for scale. It comes in a granular form. So many tablespoons amount to use goes by pot diameter, your pot looks to be 10 or 12 inches in diameter. Work granules into top inch or two of soil and water. Plant draws up insecticide, bug sucks on plant and dies. I would clean off as many as possible too.

Added, it also lasts for a while, I'm thinking a month, maybe more. Any pets keep them away, it is a poison. It's slow acting but works well.

One of many brands:

Also, it's hard to tell when those darn things are dead. So keep cleaning them off. Then you shouldn't see new ones. You may want to give it a good shower a few times. Those bugs produce alot of sticky residue.

wow.... is it that easy? I spent some good hours clean up the leaves and still found more after several days... will definitely try it.

You can also just clean off the scale with alcohol on a cotton ball or cloth.
