First, it should not be in a terrarium, it should be in dormancy right now. These are not indoor plants. Cut the flower stalk off. No need to feed it either. Google venus flytrap care.

Tommyr,

First of all, I shouldn't have said it was in a terrarium. It's actually in a pot with drainage holes, which is completely enclosed in a glass container as well. But regardless, I have seen countless information suggestion terrariums for V. fly-traps. My house is VERY dry and I know the plant would not survive unless the humidity was increased.

Unfortunately, ilb4l, Tommy is correct. Irrespective of whatever your sources said --vft's are not good terr plants.

The main reason for this is that vfts REQUIRE a cool/cold dormancy in order to remain vigorous. Unless one was intending on putting the entire tank into a such a dormancy OR planning on removing the vft every fall to relocate it to a chilly place to go dormant, the plant's health will decline overtime and it will die. TommyR is also quite correct that you plant should not be producing flowers at this time nor should it be in active growth. It should be dormant at this time.

A second issue is light related. Vfts generally like pretty strong light. I give mine full sun (from 9am - 1 or 2 pm) on my balconey over the summer. Light this strong is not generally possible in a terr without concurrently raising the temperature too high.

A third issue with terrs is that vfts tend to like to send their roots down fairly deep -- deeper than what terrs often provide.

Btw, most folks remove the flower spikes viewing them as a needless waste of the plant's energy. A strong vigorous plant can flower and produce seeds without it being detrimental to the plant, but typically in home culture, it is better to have the plant direct its energy into vegetative growth.

Happy growing!

You can grow them part of the year in a terrarium but if they are over 1-2 years old which is the case with commercially grown plants then they need their dormancy every year. They also need really bright light and I'm not talking a couple hours sun on a windowsill or a desk lamp unless it's rated for a 105w CFL. VFTs don't need the high humidity either. Your countless info is wrong.
Cut off the flower stalk or it will most likely die which it may do anyway without dormancy. Acclimate it slowly to lower humidity and put it outside come spring if it survives.

Tommy don't you just love it when a newbie thinks they know better than you? LOL!

OOps! Should have refreshed before I posted! Yeah, what he said, LOL!

Paul,
Thank you for your information, and for taking the time to explain things politely. Do you think my V flytrap will survive if I keep it in the terarium until next fall and then start introducing colder temps? I feel that it's perhaps too late to try to put it into dormancy this season. About the second issue, I use fluorescent lights and the plant seems to be doing well under them. The plant is also very small right now, no roots showing through the bottom of the pot, so I think the pot size is ok right now.

Taz6122,
Excuse me, but I believe tommyr was who suggested me to "Google venus fly trap care", which led me to the "countless" webpages saying that many people grow them in terrariums. I do not think that I know more than anyone on here. I responded to his comment with information I found FROM HIS ADVICE. Plus he was very short and did not give me much info or advice to go on, but instead told me to "google it". Obviously I know google exists, I came on here for specific information regarding my situation, not for someone to be short with me, and point me to google instead of taking the time to politely expain things. It's a shame that some people on here think they are so much smarter than others, that they can't take the time to politely explain things. very rude indeed.

Not all info on the web is accurate. This link is.

Who defecated on your donut Kala??

Your plant may have flowered if your lights are running more than 12 hours a day. It thinks its spring.

Would have to disagree regarding the suitability of venus flytraps for terrariums. Given sufficient light they do quite well in a terrarium, although I always suggest keeping them in pots in the terrarium to allow for sufficient drainage. I have a few dozen that I produced in vitro that have been growing in terrariums now for about 5 years. Unlike some that I've bought in the past, the ones out of culture seem to be quite happy without experiencing dormancy. Perhaps it has to do with how they were raised. I give most of them 14 hours of bright fluorescent light each day, although I have a few that I keep on a windowsill and those undergo a muted dormancy each winter. They go outside in summer once the days are long enough.

One way that you can satisfy dormancy is to put the pots in plastic bags and pop them in a fridge for a few months. I do this with my northern pitcher plants to get them to flower. Kept at 34 degree F for about 3 months the leaves remain green and the plants will flower when taken out.

Considering that yours has decided to flower it might be better to allow it to continue growing after removing the flower stalk. As long as it keeps producing new leaves large enough to replace any that turn black it should be fine. Progressively smaller leaves indicate it is declining or going into dormancy

Lycopus, your vft experience is rather atypical but I congratulate you on your success all the same.

Taz, the first comment Tommy posted did come across as rather .... snooty, shall we say? While he very well may have not meant it that way or not, it is one of the drawbacks to typing -- verbal nuances are often lost.

Kala, you could do as Lycopus suggests or go ahead and put the plant on a cool/chilly well lit windowsill if you have one to at least induce a mild dormancy.

There was nothing "snooty" about my reply. Period.

These are not indoor plants/terrarium plants. Although some people may try keeping them indoors they do not normally do well UNLESS given a proper dormancy period.

But feel free to do what you wish.

Its a very temperamental plant, it can't handle, miracle grow or other fertalizers, tap water, or the traps opening and closing to many times, the nursery where I bought it from gave me a print out about, how to take care of the plant, it said to put a few holes in the lid, let a week go by, put a few more and let another week go by, then the lid/clear plastic pot can be removed without the plant dying from exposure to the outside atmosphere.

I also allow my VFT flower. Cutting the flower stalk is a sound advice for beginners who may be growing their plants in stressful condition. But once the grower becomes proficient & is now familiar of the plants requirements. No harm allowing it to flower.
