My biggest orchid is getting a bit rampant, it’s ariel roots are slowly growing across the cupboard. The smallest one is gradually dying. I think I need to give its roots a bit more air and fresh orchid medium. The middle one seems OK although it’s flowers only lasted a couple of weeks. The house isn’t very warm (usually between 18 and 20°C, sometimes as low as 16°C) but I’ve made sure they are not in a draft. I found out they like to grow in clear plastic pots, they like the light getting to them. I’m planning to repot after the flowers die off… Any advice about ariel roots. Can I cut them back…. I don’t want to damage the plant.
