QUESTION: hello . i have a venus fly trap i fed it a bug about 2 weeks ago and now it open its mouth i tried to feed it but didnt want to  . is their something wrong?

ANSWER: Hi Jose,

There are a couple factors that could be affecting the trap.  First, traps will open and close only a few times.  After that, they stop working.  This is why it's not a good idea to artificially trigger the traps.

Second, traps will stop working if the lighting is too low.  The most common mistake growers make is growing flytraps indoors or in shade.  Flytraps grow best outdoors in full sun.  It takes a lot of energy to open and close their traps, and they get their energy from sunlight.  Without proper sunlight, your plant won't have sufficient energy to sustain its traps.

On another note, you don't need to feed your plant.  While it's fun to watch it close in on an insect, flytraps are adept at catching bugs on its own.  In the great scheme of things, feeding your plant is actually the least important part of its care.  Strong sunlight, mineral-free water and well-drained, acidic soil are what's most important.  Without these things, no matter how many bugs you feed your plant, your plant won't thrive.  

Bugs only provide the materials for the plant to produce new growth.  However, the plant must get its energy to utilize these materials from sunlight.  Besides, flytraps are adapted to survive on minuscules amounts of nutrients, so they really don't need a lot of bugs for proper growth.  One bug a month will do it.  And when you grow your plant outdoors, there will be ample opportunities for your plant to capture insects on its own.

QUESTION: nice advise. but when my vft open its mouth the mouth was pilling back a little . what is up with that ?

Answer
That occurs when the plant is acclimating from high humidity to lower humidity.  It's normal and many times unavoidable.  Look for new growth.  When the new growth matures, it'll be perfectly acclimated to lower humidity, and you won't have that problem anymore.

Good growing!
