Astrophytum myriostigma cv. ONZUKA
cactus seeds

Astrophytum myriostigma cv. ONZUKA is probably the most beautiful, sought after and attractive of all Astrophytum. The cultivar ONZUKA has snowy-white, heavily speckled epidermis with fabulous markings. It was created in Japan around 1974-1977 by Mr. Tsutomu Onzuka (hence the name).

There is no pre-treatment of the seeds required.

The seeds are sown in mineral-based cat litter (no clumping litter) or perlite (germ-free) in plastic-pots. Please sow the seeds on the mineral soil. Bigger seeds need to be covered with the mineral soil, small seeds should remain on the surface.

Then put the plastic pot in a zip-lock bag - with a pot size of 6 cm , a zip-lock bag of size 12 x 17 cm is recommended . Fill in the zip-lock bag as much tap water with a few drops of universal fertilizer, so that after the absorption of the substrate a few mm of water remain on the bottom. 

Location: on the windowsill or in a small greenhouse in partial shade, daytime temperatures at about 73-83 F, somewhat lower at night at 68-72 F. 

Price is for 5 seeds
