G'morning oriky,
can you have any tips for selection of hanazono seedlings?
Since the character of hanazono will appear on a matured asterias, it is impossible to select when seedlings were very young.
If you grafted a seedling, you can see the character within two years but you can not select before the grafting.

Of all seedling photos that i have viewed...yours is the neatest
Peoples just scater their seeds on top of the media
But you arrange them neatly
Keep up the good job

G'morning Edwin,

I also scater seeds on top of media.
I think you saw my photos which were after repotted.
I repot 25 seedlings in a 10 cm square pot always.

This is slightly off-topic but Frank, when you repot tiny seedlings, do you have to moisten the soil a bit in order to make a hole? Mine cave in if the soil is dry and I am unable to get the roots in there. But common wisdom is that you need to wait a week or so to water until roots have healed from being removed from their original pot.

G'morning RichR,

I use two ways to repot very young seedings.
1. Cut tap roots of seedlings
Seedlings will be dried for 1 week before the potting
2. No touch on roots or trimed off fine roots only
Seedlings will be in pot without drying process
Soil in a pot was watered from bottom of the pot and so the soil is wet completely.
This condition is used for both 1 and 2.

You can see the repotting affects on the growing speed.

Those seem huge for 4 months old. Mine are still about the size of a pin head at 4 months.

G'morning RichR,

Since seeds were sown November 2018, seedlings are 1 year and 4 months old.

G'morning dwood5513,
Can you explain this setup ?
Why have you not planted the strombo in substrate in pots ?
Doesn't transferring them into soil harm the roots ?
What is the lighting/temperature needs for this plant ?
At what stage will you transfer them to pots ?
A solid plastic food container with a lid is used.
The main substrate is 2~4 mm pumice sand and top layer is 1~2 mm zeolite which is crashed permeable rock.
A tissue paper is laid over zeolite.
I used a normal method for fine seeds including this species before but it did not work well.
The germination rate was reasonable but small seedling went down into gaps of substrate grains and disappear gradually.
I found red flowering of this species were sold with a reasonable price, not expensive in Japanese E-bey.
I also found this method on the website of a Japanese professional cactus nursery.
The top is just a tissue paper. It will break down soon. I think rooting will be no problem.
The plastic container is accommodated in a large plastic box kept in my greenhouse.
The light is natural. No heating facilities are used.
The maximum temperature should be 40 'C in daytime and 15 'C at night.
I understand the maximum temperature is too high but it is not easy to reduce.
I will repot them when they reached to 2 mm in diameter, possibly it is one year old.
It is the 1st trial of the method for me.
Frank
Hi,
Are you still using this tissue technique for Strombocactus seeds? Seems like a great idea. When you say tissue paper, do you mean paper towels, toilet paper, paper napkins or tissue wrapping paper? Do you ever get mold or fungus growing on the decomposing paper?
Thanks!

I do not use the tissue technique anymore.
1 year old seedlings propagated by the tissue techinque were repotted in normal pots kept in a plastic box.
100 seedlings were repotted and it is enough strombocactus seedlings for me.
The paper is a facial tissue.
I used a fungicide and the tissue paper was just kept for 1 year. I could not see any mould and fungus during that time.

Hi Frank, thanks so much for your posts. It was quite a learning for novices like me. One question, do you have holes in the bottom of pots in which you grow your seeds? And also holes on the top of lid for ventilation?

Yes There are holes on the both bottom of pots and the top of lid.
