hello,
what can cause phalaenopses' leaves to stop growing?
the problem: 2 phalaenopses (in same room -- with lights) have the
latest leaves ~ 1 inch long (for 6 months (at least))
1 has 2 leaves only (actually 1.25 leaves -- 1 leaf is only 1/4 inches
long)
the other has 3.25 leaves
please advise



Is it cool in the room? Phals are pretty sensitive to temperatures
below .... oh around 58F or so. They can sulk for weeks if not months
after getting cold. If that isn't it, and you haven't repotted
recently, you might want to give that a try. No roots = no growth.

Rob's Rules: http://www.msu.edu/~halgren
1) There is always room for one more orchid
2) There is always room for two more orchids
2a. See rule 1
3) When one has insufficient credit to purchase
more orchids, obtain more credit

thanks, Rob
the room they are in is 70 degrees (minimum)
both have root growth (the 1.25 leaved has a lot of root growth plus it is
growing a spike which is IMHO is a reason for concern (i don't know whether
the 1.25 leaves are sufficient for spiking?))
thanks,
sincerely
