Beautiful blooms Lin. I'm so jealous of everyone's blooms. I'm still learning about the proper way to water my hoyas. It's nearly been 100 for over a week and I changed the potting medium to a mostly orchid bark mix. I thought I'd have to water every day but surprisingly the mix stays moist for a few days. Mine are in dappled shade and the humidity is high in the morning, around 66% by afternoon it's 36%.
