Nice flowers. My Turbs are flowering now also.

I had terrible results with organic substrates for sowing." Agree i don't use any at all . I use small sized Pumice mixed with sandy soil and spray the seeds with hydrogen peroxide then rinse with water before sowing. I also add diatomaceous earth powder to discourage insect pests.

Pictures taken with a big camera not my phone. Very dry and bright area with all the Limestone reflecting the sunlight. The Echinomastus could be warnockii not mariposensis ?

Thanks there will be a video my kids will make with way more pictures and plants youtube " cactusduty"

West Texas cactus from Big bend to Guadalupe Mountains to Franklin Mountain state park. Ariocarpus were photographed in big bend and the Epithelantha in the Guadalupe Mountains. Epithelantha were hard to find but the Ariocarpus were everywhere and often in the shade of Bushes or rocks. Echinomastus ...

I use normal sandy soil volcanic in origin mixed with Pumice which is also volcanic . Mexican cactus come from sedimentary soils of limestone origin so I add Gypsum. I just started though a year or so ago well see if it makes a difference. No organic wood products. I've tried them and don't like the...

They look very happy Mine grow much slower and less green in color. I had probelms with A. retutus from 2012 many died I think bad soil. Kotschobeyanus seem the easiest to grow less rot prone I have many now.

Conophytums start growing in Autumn so I think your plant is OK to start growing now. You're right in Summer not much water and shadier location.

Hi Hanazono, Did you graft that Ariocarpus fissuratus to get it to divide like that ?

Arizona valley weather is wonderful most of the time and only get brutally hot starting in June)."

yep I used to live there five seasons they divide summer into two parts dry and wet . I wouldn't water them until spring

Notocactus ottonis ? South American for sure

Looking good The northern hemisphere Spring is almost here so seed planting time

I trade extra cactus I grow from seed for species I don't have . I used to sell on Ebay but new tax laws have pretty much stopped that

I grow Lithops in sandy soil Plus Pumice 50% -50% . I think DG will work fine mixed with some kind of soil . There is a grower in the San Fernando valley that grows hundreds of Lithops in that kind of soil mix. "Succulents of the Veld ." What kind of soil IDK I think most people buy someth...

Cactus Duty on Etsy sells seeds but the selection is very limited All the Ariocarpus sold out quick because they sold way below market but more will show up in summer hopefully ...
