My Christmas Cactus is already blooming. I've had my Cactus in the same south window for as long as I've had it (7 yrs). It grows fine during the summer because I have mini blinds to block out the hot sun. I have two questions actually: 1. Why is it blooming so early and will it bloom again for Christmas? and 2. How or what can I do to make it bloom later? I usually have blooming at Christmas time.
