I posted about this #Dracaena awhile ago. It looked like sunburn or underwatering so I moved it to a window thats bright but always has the shade down to avoid direct sun. It’s been in the new spot for 3 months but no improvement. Any guesses? I struggle with this plant the most and it’s supposed to be one of the easier ones it gets 40%-60% humidity, watered every 10-12 days, has drainage. The tallest one is doing better than the others, if that’s a clue! Has anyone had good luck with a Warneckii? How often did you water it?
