Venus fly traps are native plants and really cool


One group of plants that seems to fascinate people, particularly children is carnivorous plants. The one we think of first is the Venus fly trap, which is actually native to North Carolina. Its range is small and encompasses a small area near the coast along the border of North and South Carolina.

Venus fly traps are difficult to grow. They are also protected, so don’t try to find them and dig one up when you’re in the Wilmington area. There’s a thriving black market business, and getting caught in the middle could be costly.

People have a misconception that because these plants are only seen growing in pots they must be tropical. This obviously isn’t true. Winter temperatures in that locale can dip below 20 degrees.

Venus fly traps must endure a cool period during the year. The key here is that they must be allowed to go dormant during this time. They shouldn’t be fertilized or fed with insects. It’s winter to them.

Plants also require fairly high light levels to thrive. Native specimens live in a naturally humid environment but they adapt well when humidity levels are lower. Many people try to grow them in terrariums with other plants and don’t allow them the dormant period they require. The fly traps inevitably perish.

These curious insectivores should reside in a place with good light for a long duration. Plants respond well to an outside environment, at least for most of the year. Around here there may be times they should be moved inside. However, one should choose an area that would not encourage growth.

One problem many people have is that when Venus fly traps are first bought they already are on a downward spiral. Likely they have been subjected to insufficient light and improper watering. These plants like lots of light, but if you place them directly from a dim to a sunny location without conditioning them they will sunburn and die. Increase sun exposure gradually.

Proper watering with rainwater or distilled water is best. Most tap water around here is too hard and plants struggle. In their natural habitat fly traps grow in boggy areas. That might make you think they require lots of water. They don’t.

Soil should be well drained but kept moist. Plants should never be wet. This is especially true in winter when they’re dormant. Watering into a tray like many do for African violets is probably the best method. Never allow water to remain in the tray very long during winter.

Above all, don’t over fertilize them. Venus fly traps require infertile soil to thrive. Don’t use commercial potting mixes with fertilizer in them. A mixture of peat moss and very coarse sand or perlite is good. I like sand because it is heavier so pots are less likely knocked over. Sand also won’t float to the top of the pot after a rain.

Venus fly traps can be difficult mostly because their requirements are different than most of our plants. They’re really cool though.

About tedmanzer

I grew up in Old Town Maine and got a B.S. at the University of Maine in Plant Sciences/ minor in Botany. From there I moved to West Virginia and earned a M.S. in Agronomy at WVU. I also met my wife there. She grew up in rural WV as the daughter of tenant farmers who raised cattle and hogs. Their lifestyle at times was one of subsistence and I learned a lot from them. I've always been a foraging buff, but combining my formal botanical knowledge with their practical 'Foxfire-type' background opened up my eyes a little more. I now teach agriculture to high school students at Northeastern High School in Elizabeth City, NC. My wife teaches with me and we make a great team. I also write a weekly nature/foraging column for the local paper (dailyadvance.com) and frequently publish articles in several other newspapers in northeastern North Carolina. I also have written several Christian nature/adventure novels that I plan to publish eventually. One is a five book family saga I call the 'Forgotten Virtues' series. In the first book, Never Alone, a young boy comes of age after his father dies in a plane crash, and he has to make it alone. Never Alone is now available in paperback, Kindle and Nook. The second book, Strange Courage, takes Carl from his High School graduation to his recovery from a nasty divorce. The third book, Second Chances, takes Carl from his ex-wife's death and the custody of his son to his heroic death at age 59. The fourth book, Promises Kept, depicts how his grandchildren react and adjust to his death. In the final book, Grandfather's Way, his youngest and most timid granddaughter emerges from the shadow of her overachieving family and accomplishes more in four months than most do in a lifetime. I use many foraging references with a lot of the plants I profile in these articles in those books.
