Hello guys,I would like to ask you, if anyone can identify what is happening with my trees.Both of those trees were indoor and about two weeks ago I put them outside. Few days ago i have noticed that the trunks are turning white from the bottom.Is this some kind of fungus or just a reaction to "rain" water? Thank you!!!

This is scale / carbonates buildup. It is normal, and I would have expected to see it already before moving it outside. How sure are you this is new?

I am like 98% sure .
So it is not any problem and the trees should be fine then?

How high it should climb ? Is it possible that the trunk is going to be all white for certain period of time ?

Thank you for your reaction, i appreciate it.

Unless you shower the whole tree in tap water it will not climb much higher.

Hallo all! Same here with my dawn redwood forest, some suggestions? I’m using distilled water. I also have some spots on the leaves…Some clue?
The overall status of the plant seems fine. It grows a lot during last month.

Hard to say from those photos. But it cannot be lime buildup from distilled water.

The leafs seems like something that came with the last rain. Maybe there were lots of pollen in the air? Maybe some kind of polution that got stuck in the rain. Anyway it looks like it would come off with a spray with your distilled water.

The trunk is a mystery to mee. I don't have a clue what it is, but I would not be awake at nights over it. Just check if it is increasing. If so check your dustilled water that it is really calcium and carbonate free.
