Low Light Cactus Question
We bought my mammillaria at Cactus Jungle about four years ago, and it has been pretty healthy since then, though it never flowered since we got it (despite fertilizing).
About a week or two ago after watering it, it started to get smaller and paler, almost like it is collapsing in on itself. As pictured, it is now half the size it was before the last time I watered it. I always err on the side of not watering it since I know overwatering can kill them, but I’m not sure what went wrong this time. I usually water it every four weeks or so (sometimes longer). Is my cactus salvageable, and do you folks have any suggestions for reviving it?
I haven’t fertilized it yet this year, so that is also an option. I live in an apartment that I know doesn’t get as much light as the cactus needs, but it hasn’t proven to be an issue until now.
Any advice is welcome and appreciated. Thanks for your time!
I don’t think the plant is savable. It’s hard to tell for sure from the photo, so if you want to bring it in to the nursery we can take a look and see what we can do to try and save it.
You were probably watering the correct amount for not getting a lot of light, however those conditions generally mean that a cactus will have a limited life. So 4 years without a lot of sun seems like you did a good job keeping it healthy as long as you could.
If you want we can suggest a spiny plant that can handle lower light levels to replace it.
