Amaryllis care requirements
water
Keep soil consistently moist but not waterlogged during active growth and flowering. Reduce watering gradually after flowering, then keep dry during the dormancy period (6–8 weeks) when the bulb rests.
soil
Use well-draining potting soil mixed with perlite or sand. Amaryllis bulbs must not sit in wet soil. Plant bulbs so the top third protrudes above the soil line.
light
Provide bright, indirect light once growth begins. After flowering, move to a very bright location (ideally sunny) to encourage foliage development and bulb strengthening for next season's bloom.
