Following are the results of a [i]Melocactus matanzanus[/i] rehabilitation project I carried out at Bach's Cactus Nursery (Tucson, Arizona) some twenty years ago. I decapitated the cephaliated aberrant apical offsets from some mature plants that had been damaged by red spider mites. The severed surfaces were dusted with powdered sulphur as a prophylactic and put aside to dry. When sufficiently calloused, the offsets were potted up using my regular soil mix with the surfaces just resting on top of the soil.

Please excuse the quality of the photographs - they were taken before the advent of digital cameras.

Hi, I am new on this forum. I am a cactus grower from Poland. I started to cultivate Melocactus just recently, but they have already become one of the most interesting genus for me.
I found excellent movie about hummingbirds in which they pollinate Melocactus species (the species name is not mentioned) from Brazil. I still remember excellent pictures by Marlon Machado published on this thread. You can watch this in 32:45 of the movie. Best regards, Piotr.
