Cactus Blooms

Anonymous added on February 27, 2012 | Answered

I have a 12- or 14-year-old golden barrel cactus which (while in my possession for 10 years) has never bloomed. It seems healthy and has been repotted several times. It's now in potting soil. I've added a tiny amount of Osmocote to it over the years. What could be the issue?

It may be that it is not getting enough light or enough phosphorous. Check to make sure it is getting enough light (bright light) and give it some bone meal to help increase phosphorous. This article will help you as well:

More watering in spring can occasionally bring about flowering as well, though care should be taken not to overdo it, as this can also lead to root rot.
