Ever since I got my 2nd hand dragon tree, the soil has had these yellowish peaks. Until today, I never really thought about them.
However, I added some new soil on the old about a week ago. The yellow peaks seem to be already appearing. It is also on the ceramic pot.
So far I had attributed them to calcium deposits from evaporation, but Google rather proposed yellow slime mold. I have never seen any real fungal activity in the pots.
This happens also in the 2nd generation of the plants, i.e. with cuttings.
Here are a couple of photos from a pot where some cuttings are growing.
What do you think these yellowish things are?
