Various trichocereus hybrids. This is my second year growing cacti. I've lost many due to mites. I've sunburned a few plants, underwatered others. I've gotten a lot better at growing them and have lost zero plants my second year. I've actually saved a few with might damage by treating them with spinosad and powdered sulfur. I'm not quite sure what to do for winter because I don't have a greenhouse. Last year I brought them indoors under lights. But I guess keeping them warm is a mistake because it prevents them from entering dormancy. Many of them got etiolated because they were stilk trying to grow because of the warmth but had less light available. I think this year I'm gonna try to move them to an unheated garage under some LED lights for winter so they can stay cold and go dormant. Any one else grow these?
