"I had a Venus Flytrap, but it died"...
Many people are introduced to Carnivorous Plants with
a Venus Flytrap from a grocery or hardware store. It probably
came with a plastic cup for a lid and may survive a little
while, but the
majority die. Most often, this is because people don't really understand what
the plants need to survive. Then people assume they are impossible to grow
- but flytraps are actually VERY easy to grow, once you learn a
few basics. Truth is that the plant was half dead even before
you got it, so it is no wonder you weren't able to keep
it alive! Please read on and our experience will help you understand these fascination
plants. Starting your collection with plants from DANGEROUS PLANTS ensures you have the best
stock available.
General
Do you think the Venus Flytrap is
from a tropical country or steamy rainforest? Surprise - they are only native
to NC & SC, in an area about 100 miles around Wilmington, NC! Have
you seen the movie "Little Shop Of Horrors" and hope your plants may some day
be large enough to capture small animals? Sorry, but a mature plant
is usually six to eight inches in diameter, and that is the entire plant! The
traps will usually be a maximum of 1 1/2 - 2 inches long. The
leaves consist of leaf stems, or petioles, which are usually heart-shaped, and grow
low to the ground during the winter. In the summer, they typically grow more
elongated and upright. At the end of the petiole sits the "true leaf" or more
commonly known, the "trap" The traps attract insects by secreting nectar
along the margin of the traps. Inspect the inside of the trap and
you should see 6 to 8 tiny trigger hairs. An insect needs to touch
two hairs once, or one hair twice, in order to close the
trap. This helps the plant conserve energy, by only closing when likely prey
is in the trap. They will catch their own insects when growing outdoors, but you
should feed them crickets if they are enclosed in a terrarium. DON'T feed your plants
hamburger since this rots the traps and often leads to the death of the
entire plant.
Avoid the temptation of closing the traps for
fun. Unlike muscular movement, this is a rapid growth process within the
leaf. Each trap can only close a limited number of times. Once in a while
isn't bad, but making a habit of it will actually weaken your plant, and
may even kill it. In ideal conditions, the trap will close in less
than a second. When an insect is caught, the trap will seal shut and begin
secreting digestive juices. If nothing "edible" is in the trap, it will
reopen in about a day. Prey is usually digested in 7-10 days and when the
trap reopens, all that will remain is the shell of the insect.
The typical habitat of the Venus flytraps is along the
moist edges of bogs and sandy low areas. Growth begins in Spring when the
plant sends out a rosette of small leaves and by April or May the plant is
flowering. Cross pollinate the flowers and in six weeks, the flowers will
begin to die, exposing the seeds. Let the flowers blacken before
collecting the seeds. Unless you really want to see the flowers, we
suggest you remove the flower spike, since it takes a lot of energy away
from making traps.
Summer arrives and the plant produces its largest leaves, typically
on upright petioles. As autumn approaches, the plants again return
to the compact, low rosette. During winter dormancy, the leaves typically
die back to the ground level, and your plant will appear dead. In
their native habitat, the Venus Flytraps enjoy a warm and humid summer,
but still experiences cold winters, with occasional lows of 10 degrees F.
Growing Media /
Pot Size
Our flytraps grow best in plastic pots, in a 50/50 mixture
of sphagnum peat moss (Canadian) and silica sand. Make sure not to use white
or beach sand, since it is high in salts & calcium, which will
kill your plants. Commercial plants grow in 2 and 3 inch pots, and the younger
plants live in communal trays. Larger pots are used for the plants in our private
collection - five or ten plants growing in a half gallon pot is an AWESOME sight!
Cover the holes at the bottom of the pot with plastic mesh or some long-fibered
sphagnum moss, to hold in the growing mix.
Temperature / Light
GENERAL - VFT's grow well in
temperatures ranging from 80 to 95 F. during the growing
season. If your plants aren't getting enough light, they will have
weak growth and the traps may fail to form correctly. Insect pests
like aphids and spider mites attack these plants, so check deformed leaves
closely, before assuming the problem is just insufficient light.
Apply or Orthene or Isotox according to the directions If you
have certain forms of the VFT that are supposed to be all red,
you may wish to grow them outside. They frequently remain
greenish inside, but will become completely red in sunlight, especially
with the onset of cool evenings in the fall.
OUTSIDE
- VFT's can take full sun
and the traps will frequently develop a lovely red hue. When
first putting them outside in the spring, make sure to acclimate them (in
the shade) for a week or more. If you live in an area where digging
creatures are problematic, make sure to protect your plants, or they may
become a squirrel's lunch! If you live in an exceptionally arid
area, it may be easier to keep them inside, under lights.
TERRARIUMS - A shop light can be placed over
two 10 gallon tanks, placed long side to side, for spectacular
results. You can also build a custom lid to fit on one tank.
If you don't want to get complicated at all, flytraps do well in
a south facing window during the growing season, but make sure you give
them an adequate dormancy period. Forcing these plants to grow by
keeping the photoperiod high will weaken, and
possibly cause them to die. Just trust us on this, yes we
have tried it! Artificial light is much less intense than sunlight,
so that is why we suggest longer photoperiods than they get outside
naturally. Attempt to mimic the seasons by gradually increasing the
photoperiod to 14-16 hours for "summer" and back down to 8-10 hours
for "winter". An appliance timer is especially helpful for
this.
Watering / Humidity
General - Try and keep the humidity at least
50%. Allowing tap water to sit out only removes chlorine,
leaving the harmful salts and minerals behind, so you will have to
find a way to get pure water for your plants. If your
collection is just starting, you can collect plenty of water
off your roof, in a five gallon bucket. Save a few empty milk
jugs and once filled, store them away from direct light. Another
good source of pure water is your dehumidifier. If your collection is
quite large, you might wish to purchase a Reverse Osmosis unit, for a
more reliable supply of water. These
plants like a moist, but not waterlogged soil. They will tolerate a
flood condition for a short time with no ill effect, but they may die
if submerged for extended periods of time. They can
also tolerate dry conditions, but it best to keep the soil evenly
moist.
Outside -
During the growing season, most of our plants sit in trays filled
with an inch of
water. Periodically allow the trays to go
dry, to kill mosquito and other bug
larvae.
It is almost impossible to
over water them when they are actively growing. If you are going
away, fill the trays as much as possible so they
don't dry out in your absence.
Terrariums -
The trays commonly used
under window box planters make excellent decorative trays for the
windowsill grower.
Spring to
Fall your plants can be kept quite moist, but you
don't need to keep them standing in water. While dormant, make
sure to keep the media moist and not soaking wet. Previously plastic
wrap was used to cover the tanks but we
have switched
to plate glass. The plastic
can be a pain - rips, crinkling up, etc -
but it does work just as well. An aquarium pump runs into each tank, to provide
a little air flow.
Dormancy
General - Venus Fly Traps need a dormancy
period. The plants may continue to grow, but at a much reduced rate.
During this time, the plants set the flower buds for the following
year. More importantly, they just need a "break" and appreciate the
rest.
Outside - If you live in areas which
don't get hard freezes, you can keep your plants outside. In
more severe climates, you should heavily mulch your bog gardens,
or keep potted plants in a cold frame. Rapid freezing
and thawing can kill many CP, and mulching helps regulate the
temps and reduces the wind at ground level. They don't need any
light during dormancy and can be completely buried under 6 inches of
leaves without any harm. With the onset of spring, remove the
mulch, so they can resume growth.
Terrariums - Reduce the photoperiod
and move to a cooler part of the house. Single plants can be moved
directly next to an east or west facing window. A cellar,
garage or unheated porch works fine, as long as you keep them
around 40 - 55 F. Decrease watering and keep barely moist.
Maintenance
The traps have a limited life span and generally die after the second
capture. Even if the traps haven't captured prey, they will die off naturally
and the plant will continue to grow new leaves. The dead leaves
should be removed and if fungus develops, apply Benomyl according to the directions.
Repot at least every other year in the Spring.
Propagation
| Leaf Cuttings:
remove a leaf at the base of the
rhizome and place it in any of the following: live sphagnum, a
50/50 peat, sand mix, or in petri dishes filled with water. In
about 4-6 weeks you should have tiny plants forming at the base of
the leaves. Some of them will rot first, so make sure you
inspect your leaf cuttings and remove any dead
material. |

Seed
Germination
Seed
is sown on the surface of 50/50 peat and sand mix. The seed requires a
cold period, called "stratification" and this can be imitated by
placing the pot in a sealed bag in your refrigerator. The seeds sprout
in 4-6 weeks and even the the first young leaves have tiny
traps! They sit 4-6 inches from standard shop lights, or outside in
full sun, standing in 1/2 inches of water. From seed, it may take a flytrap
4 to 5 years to reach maturity and they can live several
decades. |
