There's pictures in my other thread it's not salt it's calcium from the humidifier my tap water isn't real great for watering so I don't use the tap water I water with rain water also that root has hardened off an the bark has been falling off showing real green underneath so I'm guessing it's just growing also I know the pic sucks I had to turn the quality down on my camera to make it able to be posted and its for sure a BRT I've been keeping thorns under control and all the other stuff to maintain it
You might be able to keep higher quality pictures by opening in paint or something similar and cropping rather than turning down the resolution. High quality pictures are really helpful in diagnosing situations.
As
@leatherback said..."salt" in the chemistry sense of a metal and a non-metal combined. Not necessarily sodium chloride which is table salt. Many salts do not readily re-dissolve once they've fallen out of solution. Table salt is one of the ones that re-dissolves easier than most. The calcium and iron salts do not re-ionize easily which is why hard water is so damaging to pipes!
When you say "humidifier" do you mean de-humidifier?? A humidifier puts water back into the air. It needs to get the water from somewhere: often your house plumbing
A de-humidifier pulls moisture out of the air. It usually does so by cooling the air to condense out the water vapor. If the collection bin is clean, this usually results in pure water with no or very little dissolved salts. I would not expect water from a de-humidifier to leave salt deposits from watering.
I did see your other thread. Tip: don't trust that just because you created threads at the same time that everyone will have seen them in the order you created...or seen the related threads at all
Over time, the threads will separate in the forum and it will not be obvious which threads are related to what. If you want to reference one thread from another, it's usually best to copy in a link of the other thread:
This is my 2nd brazilian rain tree I'm waiting on warmer weather ao she can be shipped to her new home the one I currently have (FIRST bonsai ) I used to much neem and she dropped all her leaves but so far she seem to be fine still plenty of green in the trees bark

But, yeah, I did see the other thread...after words
I was wondering about the lack of thorns. No harm removing them...I like them and leave them on mine so I'm used to seeing them is all
Your new growth looks like what I would expect, but the bark in the picture above was throwing me. For reference, this is what I'm used to seeing on my trees:
It was hard to relate looking at your pictures...but it may just be the lighting and picture quality. That's not a knock on your picture taking ability! We've all been there! It's really tough to take a picture that is close and clear enough to show what you're trying to show
Especially with a hand held cell phone that doesn't want to focus where you want it too! I have been known to get out my tripod and DSLR camera when I've needed good quality pics...not that everyone is expected to have that kind of equipment
In a more direct answer to your original post: yes, it is fine for them to have surface roots. It will not hurt the tree. However, until the care of your tree has become routine, I'd aim to keep the roots covered. There are lots of benefits and few to no detriments to fully covered roots at this stage of development. If they do happen to pop out during watering, etc...as long as there is a sufficient root ball under the soil, the tree will not suffer for it.
Good luck with your tree! I really like the two I have
I may even try cuttings to get a few more this summer!
sorry if this makes no since.
Tough news. Stay strong, she'll have a tough battle ahead. Be her rock and let her struggle wash off you like the tide.
