Question
Venus Fly Trap
Hello
1) Venus Fly Trap
2) My venus flytrap died down due to low light but now has more light. The problem I have is that the new traps that are growing out are not opening at all. Sometimes these new traps (that don't open) get a black tip which eventually makes the whole trap black. Why is this? I'd like to add that there is a venus fly trap seedling that is growing in the same pot and it seems to be doing very well.
3)I believe there is adequate lighting as I have other carnivorous plants (including another venus fly trap) who are growing very well. They get about 4 hours of direct sunlight in the morning with bits of sun throughout the day until about the late afternoon where it gets full sun again for about a hour. I use purely rain water on all my carnivorous plants. The soil is peat which is what all the plants came in.
4) I live in Pretoria, South Africa which has an almost identical climate to North Carolina.
Hope you can help me
Kind Regards
Geraldine
AnswerThere are a couple issues going on. First is lighting. Flytraps are really full sun plants. At our nursery, we grow our flytraps exclusively outdoors. During the growing season, they receive 10+ hours of direct sunlight. Flytraps can grow in a minimum of 4 hours of direct sun, but it'll never look as robust as one grown in direct sun throughout the day. Your plant has the signs of being grown in low light - dark green leaves, oversized leaves, no redness, lack of traps opening and lack of turgidity in the leaves. Keep in mind that these plants need a lot of energy to create those traps, and they get their energy from sunlight. Remember, it doesn't matter whether or not you think the lighting is adequate. Your plant is always the final judge, and you'll need to adjust your growing conditions accordingly. Since you live in a climate that is similar to North Carolina, you could easily grow them outdoors. Also keep in mind that you're entering your fall season, so your plants will natural slow down and go dormant.
The second issue is fungus and soil health. With poor lighting, the plant becomes weak and isnt't capable of sustaining itself against fungus. Poor lighting also encourages fungus to grow in the soil. The signs of traps turning black prematurely is usually caused by poor root health, and fungus is often the primary culprit.
I recommend repotting your plant in a fresh soil mix, spray the roots and bulb with a sulfur fungicide and acclimate your plant for outdoor growing. For information on using fungicides, watch our video on the subject:
