WHAT??? Captain "I switch my scape monthly" let his crypts go so long they die off? Just kidding
I have never had that problem. I dont usually have anything emergent for more than 6-8 months (im impatient) so I dont really know what to say. Maybe some Osmocote caps or clay tabs would help out a bit. Are they all hardwater sp. that are slimming down? I would try some clay for those. Maybe repotting would help too. Im sure they suck alot of nutrients trying to flower. I do know that they are known for losing some mass after flowering because of the enegy it takes for them. BTW, your latest image of the Florida Sunset Crypt is probably the best ive ever seen taken. awesome job bro!
