Cactus / fukuryu

I got a small numbers of Astrophytum myriostigma cv fukuryu seeds and sowed on 27/07/2012.
The germination success retio was not too bad.
I grafted young seedlings and some of them were taken.
The photo is one of them.
I hope this should be true fukuryu and is in flower within a year.

Cactus / khoyo

I grafted several seedlings of Astrophytum myriostigma v nudum cv khoyo last autumn.
Khoyo turns the body color during autumn to spring and retuns to green in summer.
They have started to grow.
The photo is one of them, also starting to show kikkou character.

Cactus / denigrii

This degrafted and rooted Obregonia denigrii was in flower yesterday.
I bought seeds and sowed on 28/09/2005.
Several young seedlings were grafed but degrafted later.

The rooting of denegrii is not so difficult.

Cactus / aselliformis

Pelecyphora aselliformis have been starting flowers.
I did cuttings last spring and rooted 14 plants.
I found it was not difficult to root if the plant size was more than 3 cm diameter.
I added 4 more cuttings in this spring.

Cactus / repotted seedlings

I have completed repotting of 2 years old miracle kabutos which I posted on last Saturday.
Pumice sand is used as the pottingmix for a trial.
I expect a good result.

Cactus / 2 years old seedlings

I do not touch any roots of 1 year old asterias seedlings during repotting but I adjust the length of roots for 2 years old seedlings.
The photo is 2 years old asterias cv miracle kabuto under drying after washing.
I will cut tap-root before repotting.

Cactus / red fower aserias

An astrophytum asterias f red flower was in flower yeserday.
I could not pollinate because just one cactus was in flower.
It seems this cactus has never become a large body size because of frequent crossings in history.

Cactus / myriostigma

This is a normal astrophytum myriostigma.
Since I have never sown myriostigma seeds, I believe I bought seedlings from someone but I can not remember when I bought.

It is good looking but the body size is quite small unfortunately.

Cactus / coahuilense

Some of Astrophytum were in flower yesterday afternoon.
This coahuilense was one of them.
Coahuilense is very close to asterias and can make a hybrid easily.
The flower color is yellow petals and orange throat as same as asterias.

Cactus / Degrafting of Ariocarpus

Winter in here is relatively mild.
Pereskiopsis can grow in winter in my greenhouse.
They can keep leaves 1st winter when they were used as grafting stocks but loosing leaves during 2nd winter.
The growing speed of scions will be dramatically reduced when stocks lost leaves.
I degraft scions when they are 2 years of old because of the reason.
The photo is 2 years old Ariocarpus retusus v furfuraceus cv Sugri cauliflowers with short Pereskiopsis stocks, 10 mm length.
Potting medium is pumice sand. I completed defrafting and potting in this morning.
Pots are 10 cm square pot.

Cactus / valdezianus

I attached Turbinicarpus valdezianus v albiflorus before.
This is standard flower one.
I thought I sowed albiflorus seeds only but it might be mixed standard one also.
