Amaryllis plants like damp soil. A liquid fertilizer is also recommended at least once a week. After it blooms, cut off the dead flower stem and continue to care for it while it grows several long, thick leaves. After about eight months, stop watering and put in a cool, dark place and totally neglect it for 6-8 weeks. When you bring it out, cut off dead leaves, report with new mix and start watering again. Amaryllis should flower again in about 6 weeks. Once in while they need a year off so if it starts growing leaves instead of a flower stem just take care of it and try again next year.
You should water your Amaryllis about two to three times a week.
