How to bring that store-bought VenusFlyTrap Back to life!

I just wanted to help out all those people who have a dying VFT on their hands. They happen to be easy plants to grow, as long as the instructions that came with them are thrown in the fire. All you need is a sunny window, some distilled water, and a little understanding of how these plants grow in their natural habitats, North and South Carolina, and other places where they have been naturalized.

Stuff/materials:
A sunny windowsill +
That poor, sad-looking VTF you got at -insertstorehere-
Some distilled or R.O. water**
A sacrificial Tupperware container

+ if you don't have this, these plants will be happy under a CFL with a 6-10 hour photo period.

** RO means Reverse osmosis, and filter units have gotten considerably cheaper over the years. Some of the better ones cost around $300 and can be installed under the sink or with a spigot in the backyard.
You usually won't need to get a RO unit unless you end up using more that a couple of gallons of pure water each week.

Ok, so you probably will never find these particular types of VFTs at the store, but these are two I set outside a week or so ago. The one on the left is Dionea muscipula "B52" selected by breeders for it's vigor and large trap size. The one on the right is my brother's VFT, and is Dionea muscipula "Dente"- called as such for it's short, tooth-like margin-hairs.

Step 1: Understanding the Plant

P9260006.JPG
As many people know, these plants do eat bugs, thus having a "Cool" factor with little kids and Carnivorous Plant (CP) enthusiasts. But one misconception people have is that they are jungle plants. They aren't, and grow in low-mineral soils in N/S Carolina as mentioned earlier.
They require LOTS of water as well.
They have 3 basic requirements:

Lots of sun
Pure water w/o chlorine
Stuff to eat

They also have a winter "dormancy" during which they usually loose their leaves and turn into a small underground "bulb." This usually lasts from late September into early January, but sometimes earlier or later.

They can be fed any bugs you can find, as long as they are within 1/3 the trap's size. One or two small crickets a month from the pet-store is usually enough. Note: In order for the plant to actually eat the bug, it must be alive and moving. The continued struggle of the victim after the trap closes is what signals the digestive process to begin.

Here is a picture of a flower, but you will be lucky to see it until a couple of years after you buy the the plant, as the plants at the store are usually only a year or so old.

Hello. I have VFT trap, and it was small during it's dormancy, but started to grow beginning of January(i was back from almost 2 month abroad too:)and since I live in Norway - it's CHALLENGE to get ANY sun for the plant, other than lamp light. Now, all the tips/edge of the plants' leaves and the 'brach'(flower to be) has black tip, or edge. I ordered 6500 Kelvin lamps from Amazon.com coming next week. My question-is there any way those black marks will leave the plant once they get the light needed?? pls answer me soon, im desperate..tnx!
Spedy (author) in reply to Clarice73Feb 18, 2013. 7:19 PM
Hello. Unfortunately, the black parts will not go away or heal. Old leaves will naturally rot away with time. All you can do is make sure to give it the best conditions possible. With good light and pure water it will grow healthy new leaves to replace the old ones.
best of luck :)

IM having another problem...i bought a very weak venus fly trap, and it is growing very slow (almost nothing) and wont close the traps (some of them are turning black and dying). Any ideia what it is, perhaps dormancy? and what i can do to save it?
Spedy (author) in reply to rcosmoMay 5, 2011. 9:33 PM
Sorry for the late reply; I need to check my email more often. It sounds like it MIGHT still be in dormancy. Otherwise, check your water purity, sunlight exposure or for pest infestation. I hope I'm not replying too late :<
rcosmo says: Apr 2, 2011. 5:47 PM
Very helpfull. i had a dying VFT on my hand. Not anymore =) Hugs from brazil.

Sounds like aphids. Now to the search engine with you! 
daulef says: Aug 21, 2009. 9:12 PM
yep, distilled water is the key! here in australia they wont last more than a couple of weeks off our mains water.
Pull and Twist says: Sep 27, 2007. 9:26 PM
All Toys'R'Us' now carry Venus Fly Traps along with a few other carnivorous types... and as far as my knowledge goes, we have at least 2 stores in every state.
Spedy (author) in reply to Pull and TwistSep 28, 2007. 8:26 AM
Ah, yes. The mass market is now going for other carnivores thanks to Tissue Culture technology. A common one is "Sarracina Pupera" the purple pitcher plant. It's kind of squat with a ruffled collar around the mouth of the trap. I might do an instructable on those and any other store-bough CP's. I heard they were even putting rare Asian pitcherplants in stores like Home-depot and Lowes.
Dr_Remag in reply to SpedyAug 20, 2009. 7:31 PM
I got mine PPP from the store completely green, but I got a dish for it and my fly traps and they are beginning to become purple in color.
clibanarius in reply to SpedyOct 4, 2007. 1:47 PM
Yep, our WalMart has had two different species of Nepenthes for sale in the last six months. The first batch arrived in the summer and went from magnificent (and $19) to pathetic (and $5) in a matter of weeks; I "rescued" one at the clearance price and it's recovering nicely. The second batch has only been there a couple of weeks. However, these can be BIG plants and I'm not sure I have the room for more than one!
Spedy (author) in reply to clibanariusOct 4, 2007. 3:39 PM
wow, neps at wal-mart? that's a sight Nice to see that you are growing them successfully.
Spedy (author) in reply to SpedyAug 9, 2008. 8:48 AM
Just to re-post: Yes, they get HUGE if you don't trim them. I have one going in the bathroom that has a vine like 4 feet long.
cafegurl says: Oct 23, 2008. 12:11 PM
Venus fly traps are easy to take care of if you get a healthy one from the store. All i have to do to mine is trim away the dead leaves, and water it. Other than that the occasional fly and good sunlight is all it needs. :-) Ha! parents thought i couldn't take care of them, they thought it was a hard plant to take care of. I proved them wrong :-)
Solderguy says: Oct 10, 2008. 11:41 PM
I had a Venus flytrap but I kinda murdered it, on purpose. It was a pain to take care of. Trust me when I say this, they're more trouble than they're worth.
Spedy (author) in reply to SolderguyOct 21, 2008. 4:11 PM
No way are they not worth it. These things are EASY if you find out the right way to grow them. What were the conditions you grew it in? How much water were you giving it? How much light did it receive? Did you give it a chance to hibernate?
Solderguy in reply to SpedyOct 22, 2008. 4:04 PM
It grew fine, I put it in a large plastic bottle on a little rock, surrounded it with water, and placed the lid slightly cracked on the bottle. It grew very nice, but the bottle occupied so much space that I took it out, and decided that I'll grow it without the bottle, or let it die. It started to turn yellow and mold grew on it before I realized it was beyond saving. It was on purpose though.
MakerBreaker says: Aug 6, 2008. 10:01 AM
your using the wrong soil!!! no wonder they die....your supposed to use peat moss or peatmoss with about 30-45% fine sand
Spedy (author) in reply to MakerBreakerAug 9, 2008. 8:45 AM
Who was this comment pointed at? My plants have never died except when a family member forgets to water them while I'm gone >.>
Sunny124613 says: Jul 9, 2008. 2:53 PM
when ever it rains I put my indoor house plants outside to soak up some sun and rain(the pot has holes in the bottom so it can drain)
Mrs. Skunkbait says: Jun 28, 2008. 2:25 PM
Question about VFT... Do they actually eat house flies? Are they a good source for natural killings of these pests. I have a bunny, a cat and a dog in house and so the flies are nuts. I want to kill them but a cooler thing would be if a VFT would do the job for me.
Rishnai in reply to Mrs. SkunkbaitJul 1, 2008. 10:07 PM
I've seen them eat flies, but remember that it will take them a day or two to digest a fly and then open back up to be ready to eat another one. Unless you have a TON of VFT, the flies would probably be able to outpace the traps. But if you can get things under control by other methods and then have a couple of VFT around to eat any stray flies, that would be pretty cool.
Mrs. Skunkbait in reply to RishnaiJul 2, 2008. 7:39 AM
Thanks for the info on VFT. I don't know much about them and didn't realize it took them so long to open back up after eating. I guess it would take a TON of them to be good for controlling flies. So if I do get a VFT then I will just get it for the fun of it and not as a means of killing my pest.
Spedy (author) in reply to Mrs. SkunkbaitJun 28, 2008. 8:38 PM
CP's generally aren't effective pest controllers, except under certain situations*. The best flycatcher plant is a mostly-white variety of a plant called "S. leucophylla" *If you have a bad flea infestation, place several sundews and butterworts on the floor during the night. Place a large lamp (incandecent) above the plants to attract the fleas. If it worked, alot of the fleas will be stuck to the plants now! (This is a story I read in the cited book)
Mrs. Skunkbait in reply to SpedyJun 28, 2008. 9:37 PM
Thanks for the response. We don't have fleas just flies (real bad). But using someone else's ibles I was able to kill several with homemade trap.
parkadge says: Mar 14, 2008. 3:09 PM
Thanks for the tips, I was just looking at my VFT today and wondering was there any hope for it.
spylock says: Feb 23, 2008. 2:30 PM
My mother got a vft to bloom,but when she died it did too,I dont think it liked me very much.
Scott_Tx says: Sep 27, 2007. 3:26 PM
You can let water sit over night and the chlorine will evaporate also. I do that for adding water to fishtanks.
bratkitty in reply to Scott_TxJan 29, 2008. 10:45 PM
Chlorine will go away, but a lot of municipalities in the US are now adding chloramine, which will not go away unless heavily agitated for weeks.You should ask your water provider if they are, especially for your fishes.
Spedy (author) in reply to Scott_TxSep 27, 2007. 4:28 PM
Actually, this doesn;t make the minerals disapear. It NEEDS to be distilled or RO.
Scott_Tx in reply to SpedySep 27, 2007. 4:46 PM
Ok, thought you were just wanting to get rid of the chlorine. It wouldnt be too hard to make your own solar powered distiller either.
Spedy (author) in reply to Scott_TxSep 28, 2007. 8:13 AM
Yah, but it's easy enough to go down to the local grocery store and get a gallon of distilled water for smaller CP collections
Dr_Remag in reply to SpedyAug 20, 2009. 7:39 PM
Yeah, Wal-Mart have their GV (generic water...well I suppose the concentrated water that you are suppose to add to water is worst or the $200+ water in a wine bottle...I like tap myself) for under a dollar and it comes in distilled, spring, and drinking water. I suppose distilled would be the best, but my plants seem to like the drinking water with some caught rain water fine. Think I may have included an algae along the way though.
Shifrin says: Jan 4, 2008. 7:58 PM
Oh, How I love the "Venus Flytrap" I remember my first one! I found it at my local nursery, here in Chicago... I'm looking forward to getting more his Summer! Great Instructable... P.S. those are real nice plant you have there!
Spedy (author) in reply to ShifrinJan 5, 2008. 9:59 AM
Thanks! They're doing great outside for hibernation. Can't wait to see 'em in full growth again.
Shifrin in reply to SpedyJan 5, 2008. 10:09 AM
Yeah, I once got a flower, but my cat ate it : (, have you ever had one?
Spedy (author) in reply to ShifrinJan 5, 2008. 2:19 PM
I haven;t had one from my VFT yet, but my butterwort, another CP, flowers a bunch and they get eaten sometimes.
Shifrin in reply to SpedyJan 5, 2008. 2:52 PM
They are really pretty!
tz1_1zt says: Oct 5, 2007. 1:03 AM
Good idea for an instructable. You mention distilled and R.O water, of course rain water is also fine for carnivorous plants. The main aim is to avoid exposing the plants to dissolved minerals found in ground water, because as you say they are not present in it's natural environment. Fertiliser will kill them very quickly. I'm in the UK and grow Fly Traps in the garden. They are pretty hardy to our cool weather. Warm summers mean bigger and more impressive plants, so I might try growing one indoors as you suggest.
Spedy (author) in reply to tz1_1ztOct 5, 2007. 8:17 AM
I forgot about rainwater lol. It's a little impracticable for me, so I guess that's why I missed it. Nice to here your plants are doing well. Do you grow them in a container? or a bog garden? Growing them indoors is what I've always done, It's never humid enough outside for them here in CA
tz1_1zt in reply to SpedyOct 5, 2007. 8:36 AM
I grow Fly Traps, Drosera and small hybrid Sarracenia in a large half-barrel bog garden. It works well and incorporates a vertical section of drain pipe to indicate the saturation height of the water. Creates a nice bog environment. Larger Sarracenia are in pots, they grow too fast in the bog and take over all the space.
Spedy (author) in reply to tz1_1ztOct 5, 2007. 3:29 PM
Cool. Sounds like you have a nice collection going.
boocat says: Oct 4, 2007. 3:09 PM
Carolina Biologicals has VFTs. Now, does anybody know where I can buy fireflies to breed? There aren't any in Oregon and I miss them terribly in the summer.
A.C.E. says: Oct 2, 2007. 3:54 PM
dead flies dont have the juices a live fly does and dont struggle to make them close. a good thing to feed baby ones untill they start making stuff to attrack them is hamburger meat.
Spedy (author) in reply to A.C.E.Oct 2, 2007. 5:06 PM
NO NO NO! no hamburger! how many times do I have to say it? No offense, but that will kill the plant. I recommend wingless fruit flies.
Darkshot says: Sep 29, 2007. 8:17 PM
can you put a vid up and send me a comment when you do maybe throw a dead fly into the trap? ive never EVER seen a VFT until now and i wanna see it eat somthin :) thanks ;D
Spedy (author) in reply to DarkshotSep 30, 2007. 9:03 AM
err.. Well, I have absolutely no way to make a video. Sorry. It's pretty cool, but you're bound to find something on youtube.com :)

botronics says: Sep 28, 2007. 10:36 AM
I had one that I Iforgot to water near the end of summer last year. It "died", but I knew about those plants going dormant. I gave it a good flush with distilled water and put it in a plastic bag to conserve moisture. Then I placed it in a dark and cool area outside my house. During the spring of this year it sprouted back to life bigger than ever. Now I'm going to do the same in a few weeks. These plants must go dormant each year or they will really die and not come back.
botronics in reply to botronicsSep 28, 2007. 10:13 PM
What I mean by dark, is just out of direct sunlight. Some light is still needed for parts of the plant that is still living. My back porch works good for this. During the few weeks (SF bay area) we get freezing, if any, I'll bring it inside next to a window. The draft will kept it cool.
Spedy (author) in reply to botronicsSep 29, 2007. 2:31 PM
San Francisco? The BACPS just had it's Annual Plant Show and meeting over there.
botronics in reply to SpedySep 29, 2007. 5:03 PM
I just looked them up, The Bay Area Carnivorous Plant society will meet again in November at UC Berkley's Botanical Gardens (a great place). The plant sales sounds interesting, probably not as big as the yearly show. Missed them by 1 week!
Spedy (author) in reply to botronicsSep 29, 2007. 7:42 PM
Heh, If you;re going I'll probably see yah there. :)
Spedy (author) in reply to botronicsSep 28, 2007. 3:35 PM
Yep. I wouldn;t recommend the plastic bag in a dark place, it might encourage mushrooms. But glad to hear your VFT is doing well.
tibby_ says: Sep 29, 2007. 12:20 PM
do you know if you could hydroponically grow a venus fly trap?
Spedy (author) in reply to tibby_Sep 29, 2007. 2:29 PM
Probably. I've never tried though, the pot-and-water-tray method works for me.
Myself says: Sep 27, 2007. 11:40 PM
I think I'll have to pick up a copy of that book. Sis was feeding her VFT raw hamburger before leaving the country, and I think I'm the default caretaker now. The traps are black and looking unhappy, which might be because digestion never started, as you said. It's been drinking tap water for a week or two, too. I'll pick up a jug of distilled. You say to keep the level in the tupperware constant, is that so the plant can draw it up as needed through deep roots? I'm in Michigan but the plant is kept indoors and I'm not sure whether it wants to hibernate or not. It gets good sun in the morning but not midday or afternoon, should I put a light on a timer for it?
Spedy (author) in reply to MyselfSep 28, 2007. 8:19 AM
It's a good book. you should be able to get it at any bookstore like barns and noble or Borders. You could even get it off Amazon.com. Tap water? Yah, that's got to go. It needs that 1" of water like all the time, they ARE bog plants. :) I'm not sure about michigan.... How often do you get frosts in the winter? If it's only light frost, you can leave it outside. They will always try to go dormant, but if they don;t have a chance (slightly less water, shorter light period) they will eventually die.
Myself in reply to SpedySep 28, 2007. 9:12 AM
In the water's defense, it's slightly chlorinated lake water, not well water, so the mineral content is very low already. We had a frost warning last week. Not hard enough to scrape the car windows, but it sure had the green-thumb types worried. We tend to ignore snow until it's measured in feet. I wouldn't put a bog plant outside in a climate like this. :) The question, then, is whether I should just pretend it's always summer, with the same light period every day, or provide a little variation just to make it think time is passing! Does it matter? Also, I've been wondering if a toothpick would agitate the hamburger enough to get digestion started, or whether I really have to go bug-hunting.. ugh, I hate bugs.
Spedy (author) in reply to MyselfSep 28, 2007. 3:40 PM
Question 1: No, you could put it on a sunny window to get the light variation it needs, or get a timer for a desk lamp so it turns off automatically, and change the on-time for winter. Question 2: ABSOLUTELY NO HAMBURGER/MEAT. They NEED bugs. Crickets should be easy enough to get at the local pet store, and you could use forceps/tweezers to place them into the traps. That's what I do, only I raise my own meal-worms. :)
botronics in reply to SpedySep 28, 2007. 10:25 PM
It's the high fat content that causes rotting in the trap. Bugs are best, Mine attract ants and fruit flies. I keep it in an open glass aquarium with damp perlite. The plant sits on a saucer on top of the perlite. I have it shaded in such a way that it gets a few hours of direct morning sun, but not the direct afternoon sun so it don't cook. If the traps are a nice brite red inside, it means they are getting enough sun.
Spedy (author) in reply to botronicsSep 29, 2007. 8:52 AM
That is a very good setup and sounds well made. Glad your VFT is happy :)
Brennn10 says: Sep 28, 2007. 7:00 PM
Anyone ever visit Longwood Gardens? I got mine there...sadly it died in two weeks.
soonersseth says: Sep 28, 2007. 11:38 AM
can you get these in Wal Mart ? I live in Oklahoma
Spedy (author) in reply to soonerssethSep 28, 2007. 3:48 PM
Yah, you should be able to get VFT at any big store, I've never been to wal-mart long enough to see VTF there, but you should be able to get them there. I would suggest Home-Depot or Lowes as reliable sources. But if you are looking for already-healthy plants, I suggest ordering from www.californiacarnivores.com
Ibanezfoo says: Sep 28, 2007. 7:44 AM
What is a CFL? You should try to avoid using acronyms when creating instructions for things. It helps the rest of us out who aren't "in the know" about certain lingos.
Spedy (author) in reply to IbanezfooSep 28, 2007. 8:22 AM
Thanks for the tip. CFL stands for Compact Fluorescent Light bulb.
Ibanezfoo in reply to SpedySep 28, 2007. 9:20 AM
Ah, I see. I use those in one of my saltwater aquariums. Thanks!
Ohm says: Sep 27, 2007. 12:44 PM
Cool instructable, I well have to show this one to my Dad since he has tried a few times to grow one and each time it has died. That and I am already set for watter, we have a 6 stage RO filter for our fish tanks.
Spedy (author) in reply to OhmSep 27, 2007. 4:30 PM
wow, a 6 stage RO? how much did that cost? you might want to add a charcoal pre-filter to take out chlorine if you don;t already have one.
Ohm in reply to SpedySep 27, 2007. 11:21 PM
I can't remember exactly how much it cost, my Dad bought it for our marine reef aquarium because in the area that we live in there are a lot of minerals in the water, well water, and phosphates which kills the corals. I do think one of the first stages is a charcoal filter for chlorine. We also have an add on filter to make the water more palatable to drink and that goes into a separate surge tank to run ice makers and water taps. It's pretty insane.
Spedy (author) in reply to OhmSep 28, 2007. 8:23 AM
Wow, sounds nice. I don't think I will ever afford anything like that.
electronicfreak22 says: Sep 27, 2007. 2:14 PM
Awsome instructable. I've always wanted a Venus Fly trap but where can you get them in Canada?
Robotrix in reply to electronicfreak22Sep 28, 2007. 5:46 AM
Hey, ef22, you can get Venus fly traps /anywhere/ in canada. Look in any grocery store that has plants, or sometimes in craft stores, or in plant stores. My friend steve had a terrarium full of carnivorous plants he found around ottawa.
Spedy (author) in reply to electronicfreak22Sep 27, 2007. 4:29 PM
Hmm, you could order one from www.californiacarnivores.com like it says on the last step, but he usualy sends them nice and healthy and with care instructions that work
Spedy (author) in reply to SpedySep 27, 2007. 4:31 PM
Oh yah, remember to move them inside for winter if its too cold up there, they don;t like too much frost.
