I have a tender spot for D. auriculata. Tom gave me some seeds when I was just a wee CPer and they kept on going and going.

I like Drosera Auriculata too!

Hi WillyCKH - Looking good there! Especially in the midst in your basement disaster. Don't worry too much about the tuberous dews drying. Where I grow mine the RH is rarely higher than 35%.

They seem to love the extra light! Apoplast, you are right, the humidity drop didn't affect them at all! Drosera Auriculata Drosera Graniticola Drosera Stolonifera

Hi WillyCKH - They are looking great! Much better than my first year with tuberous dews. Glad to hear they didn't flinch at the dehumidifier.

Hi Willy - They are looking pretty good! I see the D. graniticola has decided to progress along. The D. stolonifera does look a little unhappy. I've not seen that before on my tuberous dews. To me, it looks a bit more like the blackened growing ends you occasionally get on rosette dews. Because I've not directly observed what you are seeing, I can't be certain, but even if you lose the growing tip I would expect the plant to grow another. I say this largely because that is what happens when he main growth point is snapped off on the emerging plant for tuberous dews - I am clumsy enough to know that from numerous experiences. You are clearly using a much more peat heavy mix than I use. Not sure if that the the cause, but it was a distinction I noticed when checking out the growth point on the D. stolonifera. I'll be curious to see what happens. Thanks for sharing!

I will keep it drier from now.. Hopefully it will make it ><

Hi WillyCKH - I wouldn't cut the growing end. If it's dead it should develop an abscission line and drop the dead tissue. But it is hard to know where the plant will be able to recover, so if you cut it too far back, or if the meristematic tissue is still alive beneath the dead tissue, you might set the plant further back by clipping. I'd wait it out and see.

Seems like only the two Drosera Auriculata can survive at my home... Sad but on the bright side, Drosera Auriculata are beautiful

Hi WillyCKH - They are looking good! Did something happen to your other tuberous dews?

D. graniticola looks to be not doing anything after growing 2 carnivorous leafs, D. stolonifera never came back from the fungus attack.

Hi Willy - I am very sorry to hear the other two species are struggling for you. Forgive me for offering advice where none was requested, but I would like to suggest a serious intervention. Very carefully repot the two that are not doing well.
It looks like the mix you are using is heavy on the peat moss. Typically, most experienced tuberous dew growers use a mix of 3 or 4 parts of coarse, rinsed, CP-safe sand to one part peat. Heavily water holding mixes seem to cause issues for many of the species that are used to faster draining conditions. D. auriculata ranges into areas where it experiences much higher organic content in the soil than do most tuberous dew species, which are confined to the very sandy southwestern portion of Western Australia. It is possible to cultivate tuberous dews in much "wetter" mixes, but it is more of a challenge. Okay, so if I've convinced you to repot, here is my advice on how to go about it.
You will need to carefully follow the main stolon down to what will likely be a shriveled tuber. Don't worry if the tuber looks bad, if they've grown a bit they will have translocated much of their stored energy to this year's growth, only to produce a new tuber later for the coming summer dormancy. The critical thing is do not break this main stolon! Then side roots growing horizontally from the main stolon are less critical. You can even leave much of the heavier soil mix around stolon to prevent breakage if you like, the new soil will allow better drainage. Once you've carefully extracted the plant, replant it using the 4:1 sand:peat mixture. It's easier if the sand is dry when you make the mix, so you can carefully pour the new mix around the plant. Then water it in, and don't have it sit in water for a couple weeks. Just carefully top water it every day or over other day.
Yes, repotting tuberous dews in active growth can be risky (it's all about not breaking that main stolon connecting the top to the tuber), but if you are likely to lose them anyhow, this intervention might just salvage the plant. Anyhow, I know you didn't ask for any advice, but that's what I would do.
