I have seen conflicting tips on the internet for how to care for an Amaryllis bulb after it has bloomed. What is the right thing to do once the bulb has flowered and the flowers are starting to wilt? I am growing the bulb indoors. I want to keep it healthy so that it will bloom so beautifully again.
