Help please!!
My cactus has turned purple and is looking a bit wrinkly and shrivelled. What does this mean?
I am an inexperienced cactus grower and would appreciate any advice!
Many thanks.

Just to point out that I don't mean the purple bits on top as these are flower buds. But on this subject, I have a few cacti which were flowering last year. Is there anything I can do to ensure that they will also flower this year?

You cactus is changing color because it is stressed. Depending on how often you water it could be water stress or if you have recently exposed it to more sunlight it could be sun stress.

In both cases giving the plant a little more water than normal could help change it back to more green colors, but it is not uncommon for these kind of cacti to remain in their stressed look for months at a time.

Some cacti will flower every year without any help, others will not and with those there is not that much you can do. For some a little bit of bloom stimulating fertilizer in the spring can help, but in my experience it is hard to determine beyond doubt that that has a direct effect. I think it has some effect.
It is what it is!

Thank you very much for your advice.

In fact I have recently moved it to a window which receives more sunlight so perhaps this is the cause. Would you suggest moving it back to an area of reduced sunlight exposure?

Long term it probably will like the extra sun it is getting, assuming you do not live in a hot desert...

Behind glass the sun should not go beyond stressing the cactus (ie. there is very little risk of actual sunburn occurring), but you may want to see if your current watering regimen is in tune with the new lighting conditions. Ie. the new lighting conditions may cause your pot to dry out faster because it is a lot warming in the window sill compared to where it was before.

Just be careful if you increase your watering frequency to make sure the pot still pretty much dries out before watering again.
It is what it is!
