Cactus / crossing variegation

The variegation over a nudum body shows a clear distinction.
I do not have a variegated nudum plant. People said "A variegated plant should be used as father plant when you want to create new varigated plants."

I have a varigated Astrophoytum asterias and try to crossing over variegation onto Ruri kabuto (nudum). The variegated asterias was in flower yesterday but the Ruti kabuto was not. I collected pollen. Pollen will be dried and kept in a gelatin capsule, and be stored in fridge until flowering of Ruri kabuto.

Cactus / cutting roots

Astrophytum asterias likes warm climate. The growing speed of asterias is normally quite slow but it is growing quite well in hot summer if you feed a lot of water.

Asterias has a thick tap root. If you feed a lot of water in summer, asterias is rotted out from the tap root easily.

I cut tap roots when the seedling is 2 years old. Fine roots will grow a simmilar manner to cuttings. Fine roots are never rotted out even if you feed a lot of water. I cut roots every year after that.

The photo is asterias Hanazono kabuto x superkabuto, cut tap roots.

Cactus / caput-medusae seedlings

Germination of caput-medusae is easy and seedling grafting also same.
I am not sure why but own-rooted seedlings are picky.
I can collect seeds from my grafted plants and can sow a lot of seeds.
I lost a lot of seedlings so far. It may dislike repotting.

I repotted 100 seedlings this morning.

Cactus / Onzuka seedlings

I have continued repotting 1 year old seedlings.
The photo is Astrophytum myriostigma cv Onzuka, developped by Mr. Onzuka.

Whey you germinate Onzuka from seeds, they do not become all Onzuka. Some of them will be normal myriostigam.
When seedlings are 1 year old you can crealy recognaize Onzuka character.
I selected Onzuka only and repotted 75 seedlings.

Cactus / Cauliflower

This grafted cacti is Ariocarpus retusus v furfuraceus cv Sugri Cauliflower. I collected seeds from my plants and sowed on 02/10/2010. I grafted 22 of young seedlings on Pereskiopsis stocks.

Pereskiopsis may fall leaves off when you stopped watering in winter. As the result, the speed of scion's growing is slowing down. I kept watering to Pereskiopsis stock in this winter.
It is still in winter but some of scions strat to grow.
