How do I care for a castle cactus that was exposed to freezing temps? Cactus was on a covered screen porch during a freeze.
The best you can do is to continue normal care and hope for the best. Hopefully, because it was in a sheltered location during the freeze, the damage will be minimal. The reason there is not much you can do is because when a heat loving plant freezes, the water in its cells forms ice crystals and these crystals pierce the cell wall. It is akin to poking a water balloon with a needle. You cannot fix that kind of damage. But, because it was in a sheltered location, it may not have frozen all the way through and it may only have surface damage. Give it the best care you can and if it can recover, it will.
I've had my fairy castle cactus for 6 months now and it's turning brown. It sits in an east-facing window and I've been careful not to water it too much. What should I do?
It sounds like it may be suffering from the onset of root rot - a result of too much water. Succulent plants should only be watered when their soil has dried out. At any rate, this article will help with root rot: https://www.gardeningknowhow.com/plant-problems/disease/treating-root-rot-gardening-tips-for-housplants.htm Here is info on caring for your cactus plant: https://www.gardeningknowhow.com/ornamental/cacti-succulents/fairy-castle/fairy-castle-cactus.htm
I've had a fairy castle cactus for 3 years now. I put it outside when the weather was nice and my son dropped his bike handle on part of it. It is now turning white. Is there anyway to save it?
Is it only turning white where the bike hit it, or all over? It may be suffering from sunscald. This happens when you bring indoor plants outside without acclimating them. If this is the case, is should recover, but in the future, here are some directions on how to acclimate it: https://www.gardeningknowhow.com/houseplants/hpgen/move-houseplant-outside.htm
I just purchased this cactus, with a flower, from Home Depot. It is about four inches high, with many little 'pups' growing to give it that castle look. How do I propagate it? I'd love to get a bunch of them growing in my house, not outdoors, as eventually I'd like to make terrariums and shallow groupings of different succulents and cactus.

I have had this plant for several years and it has always been happy and health. It about 10" in wide and a foot tall: quite a fat little plant. Recently, it got brown spots on it in a few places. The local gardening store told me to simple prune it off and the plant should be fine. I did that and waited about a month before replanting. Now all hell has broke loose, as the plant has an area on the lower portion that has turned a brown color and it's developed what looks like white fuzz but is actually hard. Anyway - I don't know what to do to help it. Any advice?
When plants are showing brown spots, it normally signals the onset of a fungal infection. Treating the plant with a fungicide (neem oil works well) should help take care of this - if it has not progressed to the point of no return. Additionally, it could be an insect pest, like scale or mealybug, affecting your plant. Again, neem oil can help. Here is more information on neem oil: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
I purchased this cactus and it's growing fine but has a white powder like matter. I did use some diluted peroxide a few months back but I'm seeing it again. I irritated some of the outer flesh using this but not enough to worry myself over. Take a look...I'll try and get a good picture.
Anyone know what I should do?
I just got a fairy castle cactus. How often do I water it and how much water each time? Is watering seasonal? This is my first cactus and I worry about over-watering him.
Here is a link with great care information.
