What the heck IS that?

Any green thumbs out there? There is this fuzzy white stuff on my indoor flower pot? Anyone know what it is and should I be concerned about the plant?

Bit of moisture seeping through the pot and leaving salt deposits most probably - if you wipe a finger over it does it come off and feel salty (i.e small crystals)?

If not could be fungal hyphae but I’ll put my money on mineral deposits.

Yes, Paul, all part of the aging process of the garden pot.

@michael_archer Thank you gentlemen for your replies. No Paul - there is no salty residue - could it be mould? I have a high humidity house although it hasn’t happened to 2 other pots. (But the 2 others require less water.) Can that be harmful to the plant eventually? Should I transplant it to a ceramic glazed pot instead? I didn’t know flower pots “aged” Michael but then I guess everything does in the end, yes?:wink:
