After the flowers are spent, cut off the flower stem. By now leaves have probably started to emerge from the bulb. To get your Amaryllis to flower again, it’s important to promote this leaf growth. Think of the leaves as solar collectors that convert sunlight into energy that’s stored in the bulb for the next flowering cycle. Bright light (but not direct sun) is the source of next year’s flowers. Keep the soil lightly moist and feed with a soluble plant food like Jack’s Classic at half strength about every two or three weeks. Wait to until the flowering cycle has finished before you start feeding. The best way to strengthen your Amaryllis is to sink the pot in a semi-shady flowerbed outside when things warm up next summer. Sink the pot into the soil so that the exposed part of the bulb is almost covered. Before frost, bring your Amaryllis inside and allow it to dry out completely. Keep dry and store at 60 to 65 degrees for at least a month. This dry storage period is necessary to stimulate your Amaryllis to begin its next growth cycle. Remember, Amaryllis like to be potbound, so leave it in the same size pot for two or three years.
