Cactus / khoyo

This cactus is a grafted Astrophytum myriostigma v nudum cv red bean khoyo kikkow.
I lost several good mature plants in summer and so I grafted 9 seedlings after that to maintain the numbers.
This cultivar is green in summer but the body color is turned to red bean during autumn to spring as similar to autum foliage. Since it is just the beginning of autumn, the color is orange.

Cactus / denegrii

I bought 50 seeds of Obregonia denegrii and sowed on 28/09/2005.
Although some of seedlings were grafted, I kept own root seedlings also.
Some of these seedlings have started flowering in this season.
Own root denegrii grows very slowly.

Cactus / Miracle kabuto

Astrophytum asterias cv miracle kabuto has been in flower continuously.
The flower is a bit small because of autumn.
I collected plenty of seeds and sowed in this season.
The success ratio of germaination for asterias seeds becomes the highest if you could sow immidiately after the collection of seeds.
Since it is in autumn, seeds collected from now will be for next season.

Cactus / grafting practice

There are various way of graftings.
I did a practice of the grafting using super-glue.
Scions are Ariocarpus tubercles. Since it was hard to give continuous pressure onto scions, I used the super-glue method.
Stocks are Myrtillocactus geometrizans, thick pups grown outdoor.
I think I can see the result next spring.
