I read on Wikipedia that sclerocactus wrightiae only grows on special soil with cryptobiotic crust and special mineral composition. Is this true? Did you have to use a special mix to grow it or did you just treat it like normal?
Thank you so much for this update! I hope you will do more updates :) ! I mostly grow mesembs so some of your beautiful plants might be convincing me to try cactus, they're so cute when they're small ! I also noticed in some of your older videos there is a metal tool you use for repotting seedlings, what is it ?
Depending on the greenhouse,. Outside down to -18 Celsius. Greenhouses vary between -12 to -15 Celsius. We just had though soft winters the last two years (only - 9 Celsius)
I just binge-watched all your wonderful grafting vids. how did you get pereskiopsis without spines? i cannot handle mine like you showed. on grafting tubercles, i have seedling ariocarpus retusus, can i graft tubercles from those? they are still very small(1/4 inch). and will it result in a regular cactus, or just a fat tubercle? also, do you have any de-grafting tips? on the Schlumbergera root stock, it looks like you could just add soil up to the scion base and leave the leaf buried. would that work? thanks for any info on these.
The Pereskiopsis do have spines (and i do not like them either). But you can do two things to minimize that. When the Pereskiopsis is grown in shade with enogh supply of water and nutricients, they will grow fast and the new growth will not have many spines. Also what you can do is remove the spines by cleaning the stem with a wet (glasscleaner i use) cloth or paper and wipe of the spines. I would also consider grafting on Schlumbergera, as this can give excellent results and tou do not have to bother about spines
