Hello Gabriel,
first of all, I wish you a Happy Easter holiday. I know, that many people in Mexico used to travel and took a vacation during the "semana santa".
Because of the COVID-19 situation that may not have been possible for you this year.
At least, your cacti are flowering and producing pretty blossoms. You certainly do have a pretty good selection of Mammillaria spp. and some of them do have outstanding flowers. I only do have two or three plants of that genus altogether. I could grow a better assortment of them, if I were to get rid of even more of my prickly pear cacti.
Very soon a big, but dead tree in my front yard will have to be cut down and I could leave a piece of the trunk as a small platform to grow some trailing cacti like that beautiful Discocactus flagelliformis (syn. Aporocactus flagelliformis). Perhaps my wife would even allow me to take that kinf of cactus indoors during the winter months.
