You swapped out your local laterite for mulch (& now you're sharing your secret recipe!)[b said:Quote[/b] ]I use a rather unorthodox mix at the moment; 2:1:1 sand:LFSine bark mulch.
I also do this whenever I remember. Sort-of like a petiolaris good luck charm[b said:Quote[/b] ]... and I find that a couple live sphag heads right next to the plant are often beneficial ...
[b said:Quote[/b] ]I'd go deep and narrow, but in cultivation (under my conditions) I found overpotting was a bad idea.
I'm not too sure I've paid a lot of attention to this but my initial observations indicate that root length is more a function of the environment in which the plants are growing than a species thing. In my 'dry' tank, the plants all have robust root systems (& 1 of the 2 D. kenneallyi had an amazingly huge complex of roots).[b said:Quote[/b] (homer @ May 07 2006,12:18)]As a sidenote, I've noticed that D. paradoxa has shallow roots that don't extend nearly to the capacity of a 2.5" pot. D. ordensis; on the other hand, have are more developed root system. I have four 1-year old D. ordensis plants growing in the same 4" pot, and roots are already visible through the drainage holes.
Has anyone else observed this, or am I on my own here?
