Propagation Ariocarpus fom seed

[keith]

I grew this cactus from seed only took 20 years

[Hanazono]

It is a very nice fissuratus.
I am not sure how long a fissuratus can survive but 20 years old is a good age and the plant is maintained neatly.

I think fissuratus is in flower relatively in young age.
5~6 years old is the flowering age.

An ariocarpus retusus cv Shinkawa Tama Zouge was in flower in the afternoon.
It is 1st flowering for the cactus.
I sowed seed on 11th August 2005.
The size is 12 cm in diameter currently.
It should be in flower earlier but this one experienced various issues during growing.

A rid of plastic box which accommodated in Ariocarpus seedlings was deteriorated and broken.
I bought a new one yesterday.
The original one was clear and covered by a 50% shade cloth but the new one is "pearl" and I do not use any shade clothes.
The photo is the new box accommodated in seedlings.

Seedlings of Ariocarpus grow very slowly but they will gain the body size and they need repotting.
It is spring in here and I will start to repot seedlings of Ariocarpus.

The photo is A. retusus v bicolor, sown seeds on 12th October 2012.
They are in 5 cm square tubes. I will select 20 and will move them to 6.5 cm square pots.

20 seedlings of retusus v bicolor were repotted in 6.5 cm square pots in this morning.

Looks good, they actually look bigger than I thought for 6 years growth. I guess you probably have all the environmental factors and light dialed in perfectly, but still. Are you growing any aztekium? I just sowed some seeds and I wonder what they'll look like 10 or 20 years from now. Also did geohintonia and blossfeldiana, all those real slow ones; I figure I'll be alive for another 50 years or so (at least) so I should get started early.

G'morning cosmotoad,

I use a special propagation technique for Ariocarpus seedlings,which was developed by a Japanese.
It is able to accelerate the growing speed of Ariocarpus seedlings.

I have Aztekium rittri, hintonii and Geohintonia mexicana, all flowering sizes.
Seeds were sown in 2006.
Since these seedlings grow very slowly, I grafted seedlings and degrafted later.

These are an other Ariocarpus seedlings sown seeds in 2012. They are retusus cv tri-fingers.
Unfortunately they have insect attack scars which may never disappear.
I repotted them in this afternoon.

Before repotting, in 5 cm square tubes


After repotted, in 6.5 cm square pots


I still keep may Ariocarpus seedlings which have to repot as shown on the photo.
They will go to 5 cm square tubes.

[Hanazono]

I have continued repotting of seedlings.
35 seedlings were selected including seedlings in 10 cm square pot shown on the photo posted yesterday.
Seedlings are hybrid, elongatus x fissuratus.

Removed from pots


Repotted in 5 cm square tubes

I found a fissuratus seedling sown seed in 2012 in a wet-box.
The seedling was never repotted since the germination.
I repotted it and removed from the wet-box.

On 06 July 2018 I sowed several pots of various cactus, including Ariocarpus. At 1 month I had taken them out of the bag to try grafting. This pot (below) fell behind the shelf and I could not move the shelf because it is so heavy. The seedlings spilled and were lost--or so I thought!

Last week I found these. They have been angled on the south windowsill for almost 10 months. Only 8 seedlings along the edge survived. I presume they got the least sun and most water because of the angle.

If they got any significant water at all, it was runoff from a big Kalanchoe that was not moved until last week and whose pot was pushed up against the window. As far as I remember I watered it only twice all winter. So these seedlings got very little water and lots of sun. I thought they had spilled and died!

Well, are these even worth saving? I guess it can't hurt to put them under shade and give them lots more water! I already watered them once in this picture and they swelled up within a day so I guess their roots still function...

G'morning Aloinopsis,

It seems they are health now. I hope they grew continuously in this season.

Seedlings of Ariocarpus grow slowly.
The photo is seedlings of A. retusus v furfuraceus cv Suguri cauliflower.
Seeds were sown on 19th July 2016.
I removed all fungi covering over the top-soil and watered in this morning.

Hanazono, I notice the grid fence or wiring in most of your posts. Is that to keep them off the bottom of the container or keep them seperated?
