2 of grafted Ariocarpus fissuratus v intermedius have pushed flowering buds up.
The photo is one of two.
Refer to the posts on 12th Dec, 11th Jan, and 31st Jan.

A kotschoubeyanus was in flower in this morning.
This is the same scion posted on 11th March.
It took around 1 month from bud to flower.
Seeds were sown on 22nd August last year and so it took around 8 months from seed to flower.

An intermedius was in flower in the afternoon.
The body size of scion is just 3 cm diameter.

Are you gonna hand pollinate those flowers to produce seeds?

Also I'm getting a Harrisia jusbertii soon and after a while to build up a good amount of stocks from cutting propagation, I'm planning to do a seedling graft directly onto the Harrisia using the paper cap technique. Could this work? A source here says someone uses Harrisia jusbertii for seedling grafts: http://www.geocities.ws/lauii8/seed/seedgra.html" onclick="window.open(this.href);return false;

G'morning Driller64

No I am not.
I have several matured these species and have pollinated already for seed collection.

Harrisia jusbertii is a good permanent stock for seedling grafting.
It is a standard grafting stock for seedlings in Japan.

You have to graft seedlings when the stocks are growing vigorously in spring.
Wipe sticky liquid out on cutting face of the stock by paper before setting the scion. This can minimize the black skin problem,
30~40 days old seedling will give the best success rate.

lauii8 is myself.

I thought it was you that wrote that ;)

Also forgive my lack of knowledge, wouldn't wiping the wound before grafting cause contamination of the wound and cause graft failure? Or do you sterilize the paper you use to wipe the grafting wound.

I cut new tissue papers and make small piece of papers.
One piece of paper is used just for one wiping only.
This method will not give any problem for the grafting.

I do not sterilize papers.

Hrn, interesting. Maybe Harrisia has a better immune system that allows it to resist whatever bacteria live on the paper? I don't know :/

G'evening Driller64

Have you experienced bacteria related problem with seedling grafting by yourself?
I have grafted cactus seedlings with various stocks for 55 years but I have never experienced by myself.

About 15 years ago, I bought several cuttings of Hylocereus and built up numbers from their offsets.
Unfortunately original cuttings were infected by virus and made yellow/black spots on the body.
This virus did not affected on the grafting success rate but the virus moved up to the scion and made yellow/black spots on the scion also. (no wiping of cutting face by paper)
I stopped to use Hylocereus by the reason.

I knew the virus did not transfer though a seed and I started to use 3 years old H. jusbertii as the stock.
I used around 2000 jusbertii stocks with "wiping liquid by paper" method but I have never experience bacteria/virus problems.

I currently use Pereskiopsis for the trial of degrafting.
So far I used more than 1000 stocks without bacteria/virus problems.

Yes I have been experiancing problems with rust color on the graft wound with Pereskiopsis grafting. I believe this to be either due to the stocks I am using to be low to the ground (my Peresk stock plants are being lazy so I am forced to take small cuttings) or too high humidity in the humidity chamber. I use plastic cups to keep humidity around the graft. I recently drilled holes in the tops of those cups to allow air circulation so I will see how that goes.

Also on a side note, since I only purchased a single Harrisia jusbertii plant and plan on propagating only from it, how fast does Harrisia jusbertii grow typically? The person I bought it from said in no time you will have a huge cactus but that could just be advertizing :/

I use a plastic box with lid, assumed 100% humidity.
It is possible to accommodate 35 stocks at once.
Drips will never contact scions and cutting faces.
I use 2 knives, one is for scion and other is for stock.
I sterilize knives for every cuttings.

If you could maximize the growing period, H. jusbertii will grow 30 cm per year.
It may grow continuously even in winter.
You need 10 cm length for new cuttings.
A high nitrogen potting -mix is required for the good growing rate.

It is possible to harvest seeds by pollination with pollen of any Echinopsis.

Updated photos
I grafted 12 of Astrophytum myriostigma v nudum cv kikkou, khoyo f red bean.
11 of them look normal but 1 of them shows monstrose appearance.
Normal one ( refer to my post on 16th Feb.)

Abnormal one

Updated photo taken in this afternoon
June to August in here is winter in calendar but it is shorter actually.
Grafted scions have continued to grow as shown on the photo.
The shot spot is similar to the photo posted on 3rd Feb. in this year.
You can see how much scions grew since.

Nice work Hanazono.

I have a few questions to ask.
You said somewhere that before using pereskiopsis you were using hylocereus as grafting stock. Why did you sotp using hylocereus ? Only because of the lower success rates or for other reasons ?
You also said that you used pereskia long ago as a grafting stock. Why is pereskiopsis better ? And could you graft seedlings to pereskia ? What strain were you using ?
