In zone 6b I pull the Hippeastrum bulbs out of the pots or let the soil completely dry out by late july or sept for storage. Allow the leaves to yellow which feeds the bulbs for next blooming cycle then remove any time placed in an open container until the next cycle of bloom.
In late Oct. Nov. replant bulbs 3/4 of the bulb above the soil line in slightly damp soil. Place in a warm area 70', with indirect bright light. At the first sign of leaf growth lightly water the bulb taking care the soil is light and drains well. Always empty the saucer to prevent root rot. 8-12 weeks for blooms. Plant in succession for holiday blooms thru Jan.
I never fertilize my bulbs . That is an option choice.
