They cannot have regular soil. Only specific carnivorous soil or pure sphagnum moss (not miraclegro or any with any additives/fertilizers). Put it in a bowl with *only distilled or rain water* to bottom water & a day after the bowl dries, fill up again. The drainage holes must be in the water. They like water & the evaporating water will create humidity. Don't trip the traps. If you want to feed it (indoors only), the bug must be ⅓ size of the trap.
Feed about every 4-6 weeks in the beginning, then once stable & healthy, can be as often as 2wks. Try not to exceed that, but if one catches a bug, nbd.
They need *a lot* of light. If growing outdoors, full sun. If indoors, a good grow light is required. When the traps start turning red, you know they're getting good light. I have 2-3 wands of a cheap grow light about 8" from mine.
Don't fret over dying or black leaves, they die over time (see pics).
As long as there are multiple traps, you're good. After a while, you may find what look like baby traps growing along the side (see pic). Congrats, you have babies! After dormancy, you can use this time to repot & divide. You now have 2(+) vfts!
Dormancy - every year in winter, the vft should be placed in a cold environment and given just a few hours of light a day. It will look dead. It's not. (I skipped my first year bc I also got them in autumn)
Idk if I forgot anything lol
