mammillaria longiflora stampferi


so it arrived in August 2020

mammillaria compressa centralifera

It is an interesting irony. Small plants shoot up huge flowers compared to size and large plants push out small flowers, many not even making it past the spines.

mammillaria amajacensis

Hola! Amazing flowers, nice year beginning, lucky good climate )) How did you save the wool on the top of compressa? It has to be washed away by rain...

Hello anttisepp

nothing ... I have them in the sun, at this time they do not receive water,
until February where the temperature is no longer cold ... and I let them grow as they want


I did not know that wool is washed away by the rain, it is very rare that it rains in winter

Thanks for your comment

In photos 2 and 3 you can see how the lack of water has put it in more than 2 months, however it gives me a beautiful flower

Hello dinfelu,
it is astonishing for me to see all those cacti that already did go into flower since January 1st.
My cactus plantings are in the middle of the winter season. I am not sure, how many are going to survive and how many I will lose, because of the weather we have had thus far. While I covered my plants with a tarp the first time a temperature of around 25 degrees Fahrenheit (-3.9 degrees Celsius), I failed to do so, when the temperature hit 22 degrees F (-5.6 degrees C), coupled with some rain during the day. The weather forecast had predicted temperatures in the upper 20s to low 30 degree Fahrenheit range. Thus far I cannot see, if any plants have succumbed to the cold and slightly too wet weather. I shall find out in about two months from now. I am mostly worried about the tiny seedling Turbinicarpus plants I had purchased and also the Ariocarpus cacti that I had transplanted into pots.
To make matters worse, several of teose small seedling plants I had just purchased from Miles-to-Go last spring were plucked out of the ground by one of those nasty curve-billed thrashers. That is the only bird I have ever seen uprooting cacti. The plants were not pecked, but they were lying on their side on top of the growing medium. Their small roots most likely were too dry to be alive any longer.
I am quite sure, that all of my cacti would have survived, if they were housed in a structure like a cold frame or unheated greenhouse.

hola Harald


Also in the north of my country the temperatures are very low, the cold fronts arrive one after another

Look, I show you the temperatures in Mexico City that are very comfortable, only the mornings are a bit cold


I have also had problems with cacti taken from their pots by birds, the saddest thing is that two of them died, a lohophora williamsii planted with seeds and an obregonia
