@ketsui73 -- I tend to agree with Baja on this one. I keep most of my plants outside in summer and on a south windowsill in winter, so I see some distinct patterns of opportunism going on. My 'summer growers -- cacti, agave, adeniums and tiger jaws -- are certainly happiest in spring/summer. In winter the cacti and Adeniums go more or less dormant on the windowsill, while the agave and tiger jaws continue to grow at about 1/3 speed. My 'winter growers' -- Adromischus, Aloes, Graptopetalum and Buddha's Temple -- are happiest and most active in fall, but will grow through much of the winter, spring, and early summer, and really only seem to be dormant for the hottest couple months of summer and the coldest, darkest couple months of the winter. My Haworthias are inside year round, and grow so slowly at any time that it's hard to tell if they have any seasonal preference at all!
I continue to water moderately all winter, whenever they appear to need it. The only exception is my Trichocereus cactus this year, because I'm told I need to do that and force it into a deeper dormancy if I ever want it to bloom!
