Venus flytrap Care
Guide
Light
If you are keeping your flytrap indoors, its best to keep it in a south
facing window to maximize the amount of light it can receive, as these plants
love light and it is good for them to get at least 4 hours of sunlight each
day. Alternatively, you can place your flytrap outside, but make sure it’s in
an area that is open enough to get direct sunlight, but make sure it isn’t in a
location where it could get knocked over by gusts of wind. If you keep your
plant outside, you should still bring it in during winter as flytraps aren’t
keen on frost.
Water
Do
NOT use tap water, use Rainwater
Tap water contains chemicals which will harm the plant. You can use
distilled water, reverse osmosis water, but the best water to use is rain
water. Stand them in 1 - 2 cm of rain water, but during the winter months, its
best to just keep them damp (such as using a mist spray) rather than fill the
tray up with water.
Feeding
I could say that you don’t need to feed your plant because it can catch
insects by itself, especially if it’s outside…..but I know you will anyway,
because I still do! Your flytrap will do fine even if it only eats one insect
every few weeks (that’s the whole plant, not a single trap). If you’re going to
feed it, feed it live insects.
The trigger sensors on the inside of the trap need to sense movement in
order for the trap to know it has caught live prey. Each trap can close and
open (with an insect inside) roughly 3 – 4 times until the trap dies off. If it
falsely closes (for instance, you put your finger in the trap to make it close,
which I advise against but I know you
will do it!), it can close and open 5 – 7 times before the trap dies. Each time
the plant falsely closes (due to your fingers), the plant’s energy is wasted.
This energy could be used by the plant to make even bigger traps!
Don’t feed the plant an insect that is too big. When the plant closes,
it makes itself air tight and releases digestive enzymes, but if it isn’t able
to close fully, it can become vulnerable to bacteria (the trap, not the plant).
Winter dormancy
Winter dormancy for a flytrap typically takes place from late October to
February. During dormancy, the plants leaves will die back and so it is
important to prune them. If your flytrap is outside, bring it inside,
preferably somewhere where it still gets daylight but feels cooler (such as a
conservatory).
Flowering
Usually around June/July time, these plants will start producing stalks
for flowers. Typically speaking, it is usually best to cut these stalks when
they are less than a few inches long as the flytraps put a lot of effort into
making them and can weaken the plant. If you really want to see the flower or
are planning on collecting the seeds, by all means, let the flower grow. But if
you’re more interested in having a healthier plant that produces good sized
traps, its best to prune the stalk.
Repotting
Flytraps don’t grow as fast as other plants and therefore, only need to
be repotted every year or two. It’s usually best to buy compost mixes
specifically for carnivorous plants from online retailers, but failing that,
get ‘nutrient free’ peat from your local garden centre. It is important that
the peat be nutrient free, otherwise the plant will likely die.
Growth
One of the
misconceptions of Venus flytraps is that the traps that are there when the
plant is brought are the only traps it will have and that they will grow and
that when a trap goes brown/black, the plant is dying. None of the above is
true.
Flytraps are
constantly growing new traps that you will see emerge from the centre of the
plant. These new traps will replace the old ones and the plant will continue to
make these new traps during the entirety of the growing season. Individual
traps naturally get brown/black as it is part of their life cycle. When this
happens, prune them (only the brown bits).
Another thing that some traps do when their trapping days are over is
open extremely wide to the point that the trap is no longer cupped. When a trap
is like this, it is being used by the plant purely for photosynthesis.
