Today my Mammillaria surculosa opened three flowers at once.



There is one more bud but very small.

The average temp in my greenhouse is 95 f/ 35c. 10% humidity. I have been watering all my 4" and smaller pots every other day. 6" and larger every 4 to 5 day.

Thanks for information. Much more water than my cacti was getting last summer (whole collection)! I don't know regarding humidity, but it was about 40 degrees C on my balcony windowsill and I was watering once per week in average. I used pots about 3" width.

The weather is mainly cloudy today. But Mammillaria haageana opened almost all flowers!

New flowers:

Gymnocalycium calochlorum







Gymnocalycium friedrichii

Blooming of Echinopsis subdenudata

Thank you

It is 16°С outside. So, I think that growing season is ending
A few cacti (two S.mirabilis and one T.swobodae) have buds and looks like they will not grow to flowers.

I think your collection looks lovely and well-cared for.

Gymnocalycium calochlorum – what is the diameter of that plant? First flower or not?
I like these deep pots.
