Cintia knizei from seed

[AnTTun]

Seems we didn't help much about seeds but still.. some post-sowing experience shouldn't harm. If I got all this right I should keep one mature plant I got recently away from direct sun at very porous soil mixture. Hmmm... I might try to get one more and graft it just to see if there is any difference in behaviour, flowering...

I haven't grown this plant but I have visited the greenhouse of another Sheffield member who has great success with this plant and most other slow/ tuberous rooted cacti. He had many young plants and a number of older plants from seed all kept on the topmost shelf of his greenhouse which receives full sun all day. He ventilates well though.

Big difference between an adult plant and a one year old seedling. Clearly both direct sun and high heat was too much for the little one. I can't imagine that many one year old cacti would do well in Malta in full sun, there's few enough would like it in my well ventilated greenhouse.

Hi all,

Thought I'd drag up an old thread. Has anyone had success with Cintia knizei from seed in the time since? I currently have a pot full of bright green match sticks in the baggie method and not a clue what to do next

The same as you would for any other average cactus seedling in a bag - gradually get it used to dryer air and brighter light.

Why rush to take them out of the bag, they can stay in there for a long time. My blossfeldia were in their for a couple of years. I have four geohintonia Mexicana at last & they will be staying bagged until next year.

I have 6 month old Blossfeldia liliputana in a tub and have grown Geohintonia mexicana and Rebutia cintia from seed and I would say that the latter is much faster growing. Like many other Bolivians, they etiolate alarmingly as seedlings and I wouldn't trust myself to get them bright enough in summer without cooking them. But yes, a bit longer in a bag is an option.

Never sowed them but i keep the three seedlings , that I got from a friend, on the top shelf near the greenhouse door. Same treatment for the adult plant. I water it after it flowered in (early) spring. It feels kind of soft all the time .

In fact it grew in the negative way since I care for it....

As for Blossfeldias, they are best left to grow underneath the parent plants for about 15 years until they are big enough to notice, in my experience! :-) I've now got a couple of self-sown seedlings which are perhaps 3 or 4 mm across...

Speaking of cintia.. anyone knows good grafting stock for it? I tried three so far and it grows quite elongated on all of them.
