My Mammillaria karwinskiana flowered a two months ago and recently it started growing the long white tuffs, they feel soft and feathery in the location where the flowers are. And now this bright, hard protuberance has appeared! I have been following Planta’s advice for care. I have watered and fertilized per their schedule. What is going on?? Is this a fruit? Whar are the white puffs??
