THE MOST BEAUTIFUL MAMMILLARIA

For me, MAMMILLARIA HAHNIANA is the most beautiful of all the species that this genus has to offer.

Some different varieties are created and propagated. I doubt their value.

If you offer this plant as much sun as possible, if you do not water her from above and give a little bit of lime to the substrate, you too might think of her to be the most beautiful one.

Substrate...is my standard substrate. BIMS ( = pumice ), GRANIT and LAVA are mixed up by 1:1:1. Around 10% of KALK ( = lime ) and 10% of TORF (= peat ) are added to the standard mixture.
The upper cm are filled up with lime grit. This ensures that water drains very fast and that I will be remembered to myself that this is an on lime growing species.

Growing season starts in April and ends in September or October. Flowering starts - as you can see right now - with the start of the growing season in April or May.

Winter begins in October - at the beginning or the end of - and ends in March or April. No water is given in winter.
