Recently my Bonsai tree started to loose lots of leaves. I also noticed a white powdery dusting on its leaves... is this something to be concern about and if so, what can I do to save my tree. See pictures attached. Thanks!

I like that trunk!

Welcome to Crazy!

I'd say general all purpose insecticide. Most will say aphids on them too, or a little list of common things.I too like the look and trunk of this tree. The soil doesn't look particularly great though? If you don't mind my extra opinion on it, although your topic is only about the powder.

Hello,
You think I should re-pot? I'd like to hear your suggestions. Thanks
 
Not sure what species of tree you have? But I'd say it's soil looks to be the general poor quality stuff that bonsai bought at supermarkets or not proper places, get.
Dig in to it with a finger or stick, see how condensed it is. If it feels solid then that equates to lack of oxygen for your roots.
Look up your species and best repotting time. Generally I think beginning of spring for most but this varies on your climate and species.
In my opinion, I'd suggest repotting to a better substrate.

See if anyone else comments and what they think.

This is a Fukien Tea tree, we bought it at a bonsai nursery. I do agree, i need repot with better soil. Springtime is the right time For this type of tree. Thank you for your insight!

You could try insecticidal soap as well every few days for a while then less before going to a pesticide. It's completely safe to you the plant kids and pets. Just a suggestion!
 
I use neem oil. It's safe, all natural and doesn't smell like rancid poison. And yes, it does work well.
 
Maybe it's only dust, gently clean them with water / little bit soap, could do it, which also cleans up insects.
 
Miss Iris,

Have you found out what it really is?

Also, I would put a little question into wether or not spring is actually a good time for you to repot Fukien.....

Being "finicky" as they like to put it lightly, (I call them worse!)....

I would consider a summer repot.

In spring they are already going to be experiencing seasonal change, and that little bit of change may be enough for it to consider repot another change....

Which could lead to lead drop, or other health problems because they are so finicky.

Too...

I would love to see a better pic...
As it is...

Could be any of the above problems, which for me, in regards to Fukien, isn't pinpointed very well, and hitting them with the gamut of treatments is more than likely going to set it back, possibly way, way back!

Location for proper Advice?

I love the name Iris by the way!
One of the prettiest IMO!

The less chemicals you use, the better. If that powder comes from aphids, you should be able to spot them, probably under the leaves or on/in the buds.
Usually if there are not many, I first try to kill them all by hand and frequently check if they're really gone.

Your tree suffers from two things - lack of light from being indoors and really poor soil. Both need to be corrected or your tree won't live. If you're in the Phoenix area, your nighttime lows are in the mid 60s and your day time highs are pushing 90. Put it outside. Put it in dappled shade at first and move it into the full sun a bit at a time. It will also need to be repotted this summer. You'll need to keep an eye on the watering as well - your trees water needs will be drastically different outdoors in Phoenix than they were in the house. But definitely put it outside.
