Flowering season of Astrophytum

My main collection is Astrophytum. It is quite warm today in SA and Astrophytums are in bloom. The following photos are some of my collections.

asterias seedlings, 4~5 years old

asterias cv kabuto, I think it is mixed a bit of miracle kabuto's gene.

senile x super kabuto, created by muself, I intoduced this plant once in the "Hybrid".

myriostigma cv Onzuka

As always, your cacti are stunning

Was wondering, do you have a technique for encouraging flowering in your Astros? I have a few, some of flowering size but sadly only one flowered last season. I guess good strong light and some decent periods of sun are ideal, do you have a feeding schedule that encourages flower formation? I was hoping to get alot of mine flowering this season and trying to cross a few to make some interesting hybrids.

Thanks.

Amazing once again! you have a trully incredible collection, congratulations.
p.s. i have checked out your website several times before and i am always very impressed. You are very good at grafting! is Mammillaria luethyi flowering yet?

I stop watering in the beginning of July and restart in the end of August.
This may give a good flowering, I think.
A strong sun light may be good for flowering but it is not good for growing. I keep my cactus under soft sunlight condition.

Although many Mammillarias are in flower, luethyis have just buds.
I hope they will be in flowering soon.

I do not know other places in Australia but there are two main flowering seasons in my place.
October and March/April are main flowring seasons but Astrophytum will be in flower through September to May.
I normally remove all buds on seedlings, less than 8 cm daimeter plant.
The photo on top shows seedlings with flowers. I kept buds for taking the photo.

Amazeing! I like Lewis, have visited your site many times, its the best
Im not at home, but hopefully when i get back some of my Astros will have buds, but i dont see it happening.
