Having been away for the past week, I came back and noticed that my cacti has a flower bud. My first! /proud parent.

Wondering how long before the flower will actually bloom.

Budding cactus do not like sudden changes. Sudden temperature too high, high dose fertilizer, insufficient light are causes.

I notice this with indoor growing too when the week is suddenly becomes very hot and humid and the indoor temp skyrocket. With outdoor in the open with sunshine, temp fluctuates and they open nicely. Next time when it buds, leave it outdoor where it expose to direct sun. Then again, so cactus are more picky. Astrophytum budding are more tolerant.

I figured I did change conditions.

I suspected that perhaps I overwatered it when I returned after neglecting it for a week.
So I emptied out the top gravel and true enough, the soil was super moist. :mellow:/>

Fingers crossed I didn't cause root rot

Gymnocalcyium horstii is not a difficult cactus to grow. Most Gymnocalcyium will do well indoors with very bright light though 1-2 hours of morning direct sun is best for optimal growth.
