how often do you water sans in winter
I happen to have a problem to figure out how often should I water my Sans in winter. They are in fast draining mix,terraccota pots. Room temperature around 64-66. They are in 6in pots with minimal soil,just to cover roots. the thing is my San. kirkii v. kirkii pulchra "Coopertone" leaves seemed wrinkled and half closed. I read it may due to underwatering(I water them only every 4-6 weeks)When I decided to unpot to check on roots they look completly dry and britle,no any sign of rot. Do I kill them with underwatering? last time I watered on Dec.20,2010. I'm afraid to water more.Any suggestions?
Thanks a lot
