I am currently growing a single plant (the only one surviving of 25... A cat went throught their way...) of D. dilato-petiolaris, and 5 seedlings of D. ordensis x ?? and well... they aren't growing pretty fast! Both are in 1:1 peat:sand, in a heated terrarium at 80°F and water is near the substrate surface (I know, surely too high, but i haven't find a grid to stack them yet). Although the D.dilato-petiolaris is a survivor still stressed by some agressive events, it is not growing pretty fast... So here is the question: How do you grow your petiolaris-complex sundews?
