Q.Echeveria flower stalks wilting, drying out
Echeveria “Lola”, received in bud (efflorescence emerged but not bloomed). I re-potted immediately into unglazed clay and a 2:1:1 mix of potted cactus blend, granite grit, and rinsed Perlite, and put very close under 5600K fluorescents. It has since bloomed on one stalk, while another more immature stalk turned pale and withered, first drooping and then drying out. A third stalk, barely emerged, is also pale and dessicated.
I’m quite sure I haven’t overwatered, as the rest of the plant is perfectly healthy. I’m wondering if the light might not be the issue, if perhaps I’m running them too cool to maintain flowering? But I would think that would affect formation, not kill them once emerged. Hopefully someone who knows much more about this can offer some advice!
It's possible that the repotting is responsible for the flower die-off. When plants are repotted, they often put energy into root production, and top growth appears to stop. When a plant is in flower, it's in reproduction mode, and just like mammals, if there is a stress the individual can't adjust to, the unborn young can suffer. The fact that one flower stalk is doing well shows it's adjusting to it's new situation. I would remove the unviable flower stalks.
They only bloom in high-light situations; if you’re growing them indoors and they don’t get enough brightness, your echeveria may not bloom.
Just remove the withered bloom stem and enjoy your plant.
