Hello,
As for me, I also ordered a large Darlingtonia. Nowadays it isn't in good condition, so it is dying... I don't know why, because the conditions are suitable for the plant. I grow mine in pure peat and watered with rainwater.
Can anyone tell me, which period of the year is the most suitable to make some Drosera (for example: D. slackii, D. hybrids etc.) leaf cuttings? What are your experiences?
