Sadly my little Mam. haudeana has died. Only bought last autumn. Was inside indoors, on a south facing window. Just seemed to dry up and turn to crisp . Perhaps I should have kept a bit of moisture as inside and v warm?
Ho hum. Will have to see if I can find another one and try harder next time!

Re: Mammillaria haudeana: RIP
Some of these Mamms are tricky, and do dry up apparently without warning. M. haudeana comes from an area which is normally quite hot at this time of year, and the low typically is 8C. At the moment its unseasonably cold, with temps of +16/-2, so they can be tough and resist occasional lows. Mind you, they are also pulled down into the soil so have some insulation around them.
We grow them far more above ground than in nature, and in our centrally heated houses, a teaspoon or so of water a few times through the winter is a worthwhile precaution.

Re: Mammillaria haudeana: RIP
I doubt it died just from lack of water though. Anything except a tiny seedling will go through the winter completely dry. In a hot home it might look a bit shrivelled by spring, but wouldn't be a dessicated husk. The dried-out husk means it died a long time ago, the original cause will be guesswork.

Re: Mammillaria haudeana: RIP
A problem with autumn-flowering mams is that botrytis can develop on dead flowers before they dry up completely and the fungus then works its way into the plant body. This can also be a problem with M. solisioides. However, with the low relative humidity in a dwelling house, this shouldn't happen.
Re: Mammillaria haudeana: RIP
The above is rubbish of course. I was thinking of M. hernandezii with the autumn flowers.

Re: Mammillaria haudeana: RIP Solved
What's the problem, flowers failing to open? This species tends to flower October/November when light is starting to be problematic in UK greenhouses. My plant of M. hernandezii is about the same size as the one in your photo and some years it opens its flowers and in other years it struggles. It is on the top shelf in a greenhouse which has some shade from April-September. Last autumn we had some nice sunny days at the right time here in north Surrey and the flowers opened well. I think it is just a light factor.
