Soil for Hippeastrum hybrids

Plant a Hippeastrum hybrid in a free-draining container mix and leave the upper two-thirds of the bulb above the mix. The pot must release excess water.

Best soil mix

For an indoor Hippeastrum hybrid bulb, RHS specifies peat-free John Innes No.2 or peat-free multipurpose compost. The university sources also frame the medium as a container mix rather than heavy, permanently wet garden soil.

Use a pot with a drainage hole and a free-draining medium. Avoid excess water collecting in the saucer because Hippeastrum hybrids do not tolerate permanently wet conditions.

Match the mix to the pot and setting

This target is a cultivated hybrid group commonly grown as a potted indoor bulb in colder climates and outdoors in warm climates. Keep the upper two-thirds of the bulb above the compost or soil line, and remember that the common name Amaryllis can refer to a different plant group.

Use an exact target only when one is known

Soil pH

Hippeastrum hybrids tolerate a wide pH range and have no special soil-pH requirement. UF lists acidic, loam, and sandy soil tolerances, so do not import a narrow rule from another bulb genus.
