Hey does this look like a problem? Its in the pot of a calamondin orange. If so what should I do? Thanks!
No, if you're referring to the tiny yellow balls on the soil surface. They're a nuisance though. I believe they are associated with the mushroom that is the topic of the thread Identification: - Indoor / Houseplants Fungus? | UBC Botanical Garden Forums.
It is more like a fuzzy mass, parts of it look like little balls though. It seems to be kinda taking over the soil, but I wont know if it spreads for a while i guess.
I've learned to live with the problem as it seems impossible to eradicate. I only see this for brief periods during the season when the conditions are just right. Rather than leaving it alone I get something to break up the growth and stir it around the soil; it seems to keep it in check.
One more thing. I've also noticed the same yellow balls growing on the surface of the rootball, only in greater numbers. I don't bother with those.
