Tomato Pellets - off topic
 

Okay - I admit it - this question is about tomatoes and not Orchids ...

When depotting tomatoes fresh from the nursery, I find orange pellets among
the soil.

Is that some kind of plant food pellet? How long does it last?

Thanks everyone :)

P.S.
I am learning to microgarden tomatoes before trying my hand at Orchids.
