I’m new to this group, but not new to cacti! Here’s my good fortune after six days... close to 95% germination. I purchased eight different varieties of Astrophytum asterias from Koehres. They always have very fresh seed. More photos to come in the next few weeks.

Thanks for your reply. Yes, I agree. The reddish tips on the seedlings indicate strong light. I would like to add that the photo is not the best... the seedlings are much greener. After another day or two, I will raise a bit the light up and away from the seedbed. The current closeness provides just the right amount of heat to reach the desired 80 degrees F.

G'morning Paverpicker,

It is a very good germination rate.
I hope you could mange seedlings well and could see some flowers 5 years later.

I sowed seeds of asterias related species last year. They will be repotted soon.
They are in 10 cm square pots currently.

1. Astrophytum asterias cv Oibo ruri kabuto
Seeds were given by my friend and sowed on 26th July 2018.

2. A. asterias 1st filial hanazono kabuto x red flowering asterias
Seeds were harvested from my cacti and sowed on 15th November 2018.

3. A. asterias 2nd filial hanazono kabuto x red flowering asterias
Seeds were harvested from my cacti and sowed on 22nd December 2018.
It seems these ones will be small plants due to more crossings.

Thank you for your comment. For me, the harder part is the germinating of seeds, and the easier part is growing them to maturity! I have decades of experience with Sulcorebutia, Lophophora, and Turbinicarpus, always on their own roots. A.asterias is new for me. I will keep on posting photos as time goes by. Cheers!

G'day Zonengorg,

Yes Hanazono kabuto is an asterias cultivar of Japanese origin.
Histroys of miracle kabuto and super kabuto are very clear but None can tell the clear history of hanazono kabuto unfortunately.

Hi Frank
I have read your post several times and I think it is one of the most instructive ever read in years of cultivation.
Thank you for sharing your experience with the community.

If I can I ask you some questions about it:

Does the entire cultivation process involve the use of fertilizers?

How many times a month do you water? Do you fill the pans up to the edge of the pots? what kind of water do you use (normal or from reverse osmosis)?

You write that in the sowing potting mix (zeolite, scoria, clay, coarse sand) if you do not have the scoria available you replace it with pumice. If clay is bentonite clay, the sowing potting mix is composed of only inerts substances?

The 20% of organic matter that you introduce after the first year, what is it? peat, akadama or similar other? the cactus mix of the market how it is made?

What are the average temperatures min. and max. in the 4 seasons inside your greenhouses?

Finally a little curiosity some boxes that containing the pot have a wire mesh. can I ask what is it for?

thanks Frank and sorry for the many questions and compliments for your wonderful plants!

GRAZIE!!!
Ciao Marco

G'morning Ciao Marco,

Yes it does.
I start to use old chicken manure form 4 years old seedlings.

I am not familiar with bentonite clay.
Clay which I used is too light and I mixed also heavier permeable materials.

Water every week in growing season by 5 years old seedlings and every 2 weeks more than 6 years old.
Water over pots. Pan is just received drain.
Water is rain water collected from roof of greenhouse into water tanks.

Organic matrial for young seedlings is mainly peat.
Main material of cactus mix in market is pine bark whick is normally used for any plant potting mix in here.

Max and Min temperatures in greenhouse are:
Spring: 40'C, 10'C
Summer: 50'C, 20'C
Autumn: 40'C, 10'C
Winter: 30'C, 5'C

The wire mesh supports tubes.
The size of tube is 5 cm square and 140 cm tall and hard to stand securely by themselves.

Frank, Do you sterilize soil mix by heat before sowing? Do you ever use a fungicide on soil mix before sowing seeds? Thanks.

G'morning RichR,

I do not sterilize soil mix by heat.
I use a fungicide, 3 sprays during sowing.

1. Spray over soil mix surface before sowing
Sowing seeds
2. Spray over seeds and soil mix
Setting top dressing
3. Spray over top dressing

G'morning oriky,

The degree of variegation is not stable normally.
It may be loose variegation and turns to green body or 100% yellow body and die.

Hake-han
Varigation pattern is similar to painted by a brush.
Varigation degree is very stable.

Hade-han
Varigation degree is unstable and may turn to completly green or yellow.
