Q: Why isn't my Venus flytrap growing well?
Nice plant!
A: Venus flytraps can languish or die for lots of reasons. So this may seem like an
impossible question to answer without examining all the details of a person's
cultivation details.
Let me tell you one thing, though---your flytrap is not dying because you aren't feeding it enough. Flytraps can live without
any bugs whatsoever!
I think that in nearly all cases, the underlying cause for Venus flytrap death
by beginning horticulturists can be traced to inadequate lighting.
If you give Venus flytraps the
light they need, they are really resilient little plants. If you skimp on the lighting, they are weak plants.
How much lighting do they want? FULL SUN! Bright, full sun that makes you blink the sweat out of your eyes in
discomfort. A gently lit windowsill is just too dim for them.
If your Venus flytrap is growing in a "bright windowsill" or terrarium with a single dinky fluorescent light
over it, don't be surprised if it starts dying! I have six fluorescent bulbs over my Venus flytraps, about 30 cm (12 inches) over the plants.
I've had police visit my house because I was suspected of growing marijuana. That's the kind of lighting intensity your plants need!
