A Den-phal type ? It seems about the right time of year for spikes (in the southern hemisphere). No winter rest, tho can just get slightly dry in-between waterings in winter, tho I don't think they need to in order to bloom - Mine need water less frequently in winter, due to lower temps, higher (usually) humidity here, but I don't let them sit dry at all. So, my experience is limited to just my two: bigibbum v compactum, and a bigibbum hybrid - but they both do great for me this way.
