I really hated to do this, but the nectar from these blooms was dripping on everything including its own leaves. To stop sooty mold from forming, I cut them all off. There was a total of 58 flowers and buds that I removed. I left two on the plant as they were too difficult to get to. Occasionally I get chastised for cutting flowers off from Hoyas, but when you grow inside like I do, you just can’t let nectar drip on everything.
