I have raised some Drosera macrantha ssp planchonii (tuberous sundews) from seed sown last autumn, and have just repotted about 20 dormant tubers ( they were tiny, 1 - 2mm! ) in 50:50 peat + silver (silica) sand, about 1cm deep (that's about the depth they had formed naturally in the original seedling pot), 3 to a 10cm (4") pot: does this sound ok so far? My main question is, as this is the first time growing tuberous sundews from seed, how do I break their dormancy this autumn - do I wait until they appear above soil level before placing them in a tray for the growing season, or should I start watering lightly (say by misting at first then lightly sprinkling water) around say mid-September? I'm a bit concerned as they're my first tuberous seedlings, and I feel that once they broken dormancy into their second growing season they'll be past the most hazardous stage of their little lives! *[img]http://www.**********.com/iB_html/non-cgi/emoticons/biggrin.gif[/img]
Also, and this probably applies in general to winter-growing / summer-dormant Drosera, insects are generally fairly scarce here in their growing season: what do other growers do to "supplement their sundew's diet"?! I realize insects aren't essential, but I'm hoping to feed up the tubers as much as possible to make strong and healthy plants. Does anyone culture (wingless) fruit flies, or I've heard of growers using tiny bits of fish food flakes (e.g. the Tetra stuff for tropical fish) - any opinions?
Thanks in advance for any help / tips / ideas.
