I just did my yearly pot-fest (took about 4 hours and 7 beers) and now I'm just watching the plants start to emerge from dormancy.
Lessons learned over the years, fwiw:
1) I used to repot every year, but now do it every other year. This is because:
- It's a pain-in-the-ass
3) They have survived outside down to a low of 15F without a problem: I'm talkin' a solid block of ice.
4) Each plant -- when divided after 2 years -- yields at least 10 plantlets of various sizes. I no longer completely separate each cluster into individual plants because I would run out of beer. It would yield HUNDREDS of individual plants: I leave most in clusters as I re-pot, giving each cluster a bit more space.
5) The hot Georgia sun registers 90+ F for most of the summer, and the only heat issue has been occasional overheating of the growth medium. Therefore, I protect the sides of the south-facing pots with additional containers to keep the pots in the shade (but the plants themselves LOVE the hot sun).
6) Outdoors in full sun is the only way to go: I have tried indoor south-facing windows, but the plants really need to trap their own meals, and Georgia has plenty of bugs outside! Ants, spiders, flies, moths, and an occasional wasp. During peak season, I would estimate that half of the traps are closed around bugs each day: VFTs are truly skilled "hunters".
7) Feb or March is the best time to repot. I once did it in May, and that is sub-optimal because the roots need time to re-develop -- prior to the May-June heat -- in order to supply the plants with adequate water. I did notice some signs of heat-stress on hot (80-90F) May days that year because the roots had not yet recovered from the repotting. Cooler temps (60-70F) in March -- along with strong sun -- allow the plants time to establish roots prior to the extreme heat.
I'm in north Georgia (USDA hardiness zone 7b), so your experience may vary.
I would love to hear feedback / questions, and I will post add'l pics as the season progresses: this mass of plants will COVER my table by July -- a sea of traps!
