I got a new package of plants yesterday (no pics, but soon!):
Drosera filiformis var. tracyi
Drosera binata [T form]
Drosera binata [dichotoma 'Giant Form']
I immediately repotted D. adelae into a bigger pot, as it is doing pretty good (although it has much smaller, redder, leaves than my D. adelae that came from Lowes Deathcubes -- probably because it was grown in better conditions before I got it) and I want to get some clumping going on. I also took a cutting from my D. adelae and put it in my clear box of water with my Cape Sundew cuttings -- and the Gro-Bulb I am using to keep that warm and bright promptly broke, so... ya... Bad timing.
I also repotted the D. binata [T-form], as it looks, well, dead. If I didn't know better, I would say it's pot was empty. It was in a 3" pot, I put it in a slightly bigger 4-5" pot. I do not know how they look during hibernation, but I am a bit worried. Should I be seeing a bulb or a hibernation bud of some kind? When repotting, I simply slid the old plant, media and all, out of the pot and put it into the new pot, filling around it, but i didn't see much in the way of roots on the side.
The D. filiformis var. tracyi has a few dead stems coming out of it, but it also has teardrop shaped buds of growth sitting there. I am planning on leaving it in it's current, small, pot until spring, then moving it to a 5" pot (if I'm going to have it inside during winter) or one of my new foam planters (if outside).
The D. binata [dichotoma] is the one I actually have some questions about. It has 2 pale yellow (kinda sickly looking) leaves out of it's bulb, which are kinda hanging out ready to unfurl.
How important is dormancy to a D. binata [Dichotoma]? I was going to repot it in a nice 8" pot real quick while I have time this weekend, but said pot would need to be a bit further back from the window if I went that route -- I plan on putting it on my bookshelf that is right next to the windowsill, overlooking my other CPs. I could keep it in a smaller pot (it's current 3", or a 5") and keep it on the windowsill, but I was hoping to get it in a 8-12" pot and let it go nuts with new growth in the spring.
The heating in my apartment (central air, I cannot lower the temperature of just one room) is kept at 70 degrees while I am home, I could grab a sweater and drop the temperature if need be, or even crack the window ever so slightly. Closer to the window it hovers around 50-60ish. At night, when I turn off the heat, the room drops to the mid-low 60s, and the window drops to the low 40s. Would that be cold enough for D. filiformis var. tracyi / D. binata [Dichotoma] dormancy?
I do have a VFT and S. leucophylla in the same windowsill, which appear to be having (very green) dormancies -- growth has stopped/never started with them (I rescued them last month from a local grocery store), but they don't seem to be dying back and aren't looking confused. Maybe the (extremely) limited photoperiod -- about 6 hours of direct sun -- is keeping them dormant?
Outside isn't a good option right yet (next year maybe) -- it's hovering as a high of around 31-32 degrees, and lows in the mid twenties, and they're not acclimated to that yet. D. filiformis var. tracyi might be able to handle it, I donno if D. binata [Dichotoma] will ever be able to handle that.
tl;dr: Binata T-form, Dichotoma 'giant': Dormancy required? 55-60 day/45-50 nights cold enough for dormancy?
