Re: Overwintering Suggestions for Cactus
Even Vancouver Island is pretty frigid right now - but nothing like Calgary!

Re: Mammillaria
No doubt. Kept in a very bright location, I take it, from the color and heavy wool production.

Re: can you tell me what these are?
Yes, alcohol will kill them, as will soap sprays. The eggs will survive, though, and more will hatch out - you need to repeat the treatment weekly until you're sure they're gone. The advantage of systemic insecticides is they have residual action, they will continue to kill the new hatchlings for mo...

Re: chamaecereus luisramirezii repot
If you can't keep it cold enough it may need a dribble of water once a month or so to keep the roots alive, but the ideal would be to keep it cold once it gets dry (they can even take some frost when dry) and give no water at all - that's the way to get the most abundant flowers.

Re: chamaecereus luisramirezii repot
It's growing when the light is not good enough, which is why it has those skinny tips. Also, it needs a winter rest if you want it to bloom. See: http://www.cactus-art.biz/note-book/Dictionary/Dictionary_W/dictionary_winter_rest.htm If you can't provide the cool temperatures recommended you should s...

Re: chamaecereus luisramirezii repot
The cactus is big enough that it should fill that pot with roots before long. Be extra careful with watering for the first year or two - make sure it's really thirsty before you water it. I have been watering it every 20 days give or take a day. It has been sending out a lot of roots in search of s...

Re: Opuntia azurea?
The taxonomy of that species is controversial, and it's quite variable, but I think that's correct.

Re: Seeking help from everyone, what kind of bacteria is this and how to deal with it?
You shouldn't heat the potting mix enough to completely sterilize it, more accurately you pasteurize it - hot enough to destroy fungal spores and weed seeds, no hotter than 140f - 180f is needed. Enough heat to sterilize the soil totally will not only eliminate beneficial microbes, it can produce to...

Re: Watering at night or early morning -- does it matter?
Correct - except that young cactus seedlings don't use CAM photosynthesis. Not something you need to worry about, just keep them evenly moist all the time and they'll be happy. I usually water my adult cacti in late afternoon, because I'm not a morning person and there's no sense in standing out in ...

Re: Cacti flowering in fall
I've often had Echinopsis set flower buds that don't bloom that year - they may bloom the next year. or even after several years, but sometimes they never bloom.
