Dying sprouts

[Bryan]

I have two fly traps right next to each other in 2 different pots of 50/50 peat and sand mix. I keep them in a tray of water 1/2" deep and just fill the tray when it drys out.

the other plant is fine and this one seemed fine until I looked at it today and noticed that one of the new growths has turned black... why?

any thoughts?

And for those interested here is a 3 day history of temps and rel humidity

Hmm... Maybe the sun was a bit too hot that day, and the soil too dry, nothing to worry about though.

Judging by your earlier posts, I think it is a bit sunburned because it was moved into full sun too quickly. Keep the soil moist and it will recover.

In case you are wondering, humidity isn't too much of a concern... there are people who grow flytraps in 15% humidity.

This happens occasionally to some of my plants which receive the lion's share of direct sun. I would agree that sunburn is the most likely cause. Provide a bit of shading for a bit and see if that helps . . .

Awesome thanks. I know that the majority of the "damage" is due to the harsh sun but this one was brand new and I thought it would be able to take the sun. I will move them to a shadier location.

As to the graph with humidity/temp... I was under the impression that humidity had to be high, but as a matter of practice I like to give as much information as I can... Just seems to make things flow more smoothly...

Humidity has turned out to be a much more minor issue with Dionaea, than many other genera, such as some Nepenthes, which will fail to pitcher or "suddenly" wilt under drier conditions . . .

I just want to make sure that everyone is on the right page... I am referring to the new growth that is (unfortunately) blurred in the picture. I know that the larger (old indoor) growth is sunburned.
