My brevifolia (the smallest sundew in North America) first came in its native soil. They needed potting so I concocted a great peat and perlite mix to plant them in. I delicately moved the plants into their new giant (2-3/4" square) pot/home. I carefully watered and gave them good sunlight...gradually hardening them off to full sun. They sent up tiny little flower stalks but, no matter what I did, they all gradually died on me.
I kept the little pot of sitting on the table outside, probably just because I procrastinated tossing it. One day I walk by and catch a speck or two of red in the pot. I look closer and there are several tiny seedling sitting there just as happy as could be!!!
I was thinking the entire time that it was transplanting the pygmies into a soil that was foreign to them was what killed the adult plants but after reading this thread and Panman's explanation about the long, hair roots and that breaking those roots could easily kill the plants I'm thinking it was the transplanting that killed the adults. The seedlings have grown now and have produced seeds of their own...and I'm scared to move these adults being as I don't want to disturb the roots. Being annual plants I expect these adults to die eventually (they sure seem to be holding on good for now, though!
). The last batch of flower stalks that they've put out are short...read that as S.H.O.R.T.
...if they're a 1/4" tall, they're a foot tall...and they ain't a foot tall!!!
It is kind of weird because the first round of flower stalks were all like 1" tall, maybe a touch over.
Anyhow, I'm thinking when (if?) the adults die back that I'll simply scalp off the top layer of debris...dead plants, flower stalks, loose seeds, etc., and lay it on top of the grow-mix in a larger, deeper pot. I'm really glad to find out about the root situation with them!!!!
