How can I re-pot them without breaking the stems?
Wet the soil and then carefully slide it all out in one piece. Shake the soil off of the roots and try not to break them in the process.
I don't have any other soil and the stores are closed. What other options do I have?
I live in Denmark. I have some old RockWool. Can I use that?
What about flushing the pots?
I'll buy some new soil tomorrow then. Thank you very much for the help.
