I wouldn't sweat it. You're nice to care, but he gave you no instructions at all? If that's the case, I wouldn't worry about it -- that seems like asking a great deal.

If he can't be bothered giving you (who's trying to help him), the slightest bit of info., I say screw him -- I'm not often like that but it appears he expects you to be a mind reader.

No need to apologize, your post isn't long, you're trying to help someone, after all.

Sorry, I don't grow this, so I can't begin to help; am hoping someone else who grows this will.

Hey, Carolann, that is nice of you to help your neighbor!
However, as Pirate Girl mentions, you have been put in a tight spot.

Pachira are often sold in this fashion, and it is a shame.
Yes, the rocks are glued onto the surface to prevent soil from spilling - this is one of the most
common "Mallsai" sold (Mall + bonsai). They are almost always dead or dying - in whole or part -
but occasionally there is hope. The dead trunks need to be removed, ultimately, and the living
tissue needs to be re-potted.

If it were *your* plant, I could advise you to pry the stones away with a butter knife
and warm water (to help dissolve the glue). If the plant survives, perhaps you could suggest
this course of action to your neighbor.

In the meantime, here are a couple of ideas:
1 - tip the entire plant until it is nearly sideways to see if water trickles out.
If water seeps out, you can guess that the soil is completely saturated.
2 - if you can, wiggle a string between the rocks and down the edge of the container.
Make sure the other end dangles below the bottom of the pot. Hopefully this will
act as a wick, or siphon, drawing moisture out of the pot and down the string.
