Carnivorous Plants/Venus Flytraps
QUESTION: As you can tell this is my first time growing anything from seeds
I was adding a little water today and dunno if I never noticed 2 very small white spots in the media were I think I dropped seeds,they are so small ad the same color as the peat I forget where some seeds went lol !
My question is do these seeds turn white before they sprout or after? I also noticed some green moss starting to grow but an sure there are no seed there and was told this is not a threat if seeds are indeed there they will get through the moss.
ANSWER: Hello Dennis,
Drosera seeds do not change color. When the seeds sprout, the seedlings should have bright green sprouts that will form tiny, round, tentacle covered, leaves. Hopefully the white spots are not fungus. You can treat fungus with Neem oil or other fungicides so long as they are not soap based. Usually copper based fungicide is preferable. You might want to use a magnifying lens to determine if the white spots are fungus or not. They may be other plant material or possibly tiny roots growing down from the sprouting seeds. If you think it is fungus, use fungicide as directed on the bottle. Fungus can become a major problem since it can attack seeds and seedlings before they have a chance to grow.

QUESTION: Do VFT's have a memory or intelligence because it a insect hits a trigger hair flying away it does not close but if the same insect hit 2 trigger hairs its game over for the insect How does it tell if a hair or 2 are touched?
Venus Flytraps do not have a central nervous system nd do not really have "intelligence" or "active memory," however; the term memory can be applied to the trigger mechanism to some extent.
In effect, the trigger mechanism is kind of like a bear trap in that it requires enough force on the triggers to cause the tension in the trap sides to snap shut. Since it requires more than one touch on the triggers, either two or more touches on one trigger or one touch on two or more triggers, the plant has a simple system that prepares the leaf for rapid growth "movement". Every time a trigger is touched, it releases an electrical signal. It usually takes two stimulations of a trigger to build up enough of an electrical charge release to pass the threshold of stimulation. It is set up with a threshold so that a single stimulation usually does not cause the plant leaf to react. This informs the plant that something alive and constantly moving is probably in the leaf and causes enough stimulation to cause a rapid growth in the cells along the outer walls of the leaf. Making the leaf appear to move.
