: I would be grateful to receive advice
: on a problem that I am experiencing
: with my C. panzhihuaensis
: seedlings. Five seeds germinated
: quite quickly and within about three
: weeks of being planted four of them
: sent up leaf shoots. Unfortunately
: each emergent leaf has withered and
: dried when it is about a quarter
: inch out of the growing medium. All
: five seeds seem to have formed
: strong root systems with tap roots
: about five inches long. I am trying
: some other Cycas , Dioon and
: Macrozamia species and those that
: have sent up leaves so far are fine.
: Any suggestions?
:
With a good root, they should be fine, but the reason for this could be for two totally different reasons. If the soil was too wet, and the leaves looked like they rotted off, you would want to water less, or get a better draining soil. The most probable reason will be that you didn't water enough and the leaves aborted. This happens with cycas a lot, enough that I mention in my article on water what to do about this. I'm going to guess that this is your problem, but let me know which was most likely.
