I did some leaf cuttings some 2 mths ago, putting the leaves into 2 separate pots of 1:1 peat and sand. I left the pots in the same tray of water, which was then placed in a place with some light but otherwise sheltered. Now, one of the sundew plantlets has developed beautifully, while the other leaf, after sprouting some planetlets 4 weeks back, has turned black. The plantlets, of course, are gone.
What I hope to find out, what's the problem? The 2 pots were side by side, yet in one, the plantlets died, and in the other, they thrived. I hope to find the reason so I can prevent this from happening. Thanks!
