Sow the seed during autumn in a well-draining medium. Level the medium and then sow the light seeds evenly, water gently, and cover with a thin layer of sand or bark. The seeds will germinate within two to three weeks.

The seedlings are ready to be potted as soon as they are large enough to handle. These potted seedlings will initially need a sheltered position, such as under a shade net, and can gradually be introduced to full sun.

Gazania rigida needs full sun and ample drainage. Plant it as a border plant, and use it en masse as a groundcover planting, in rockeries, or as a pot subject.

In its natural environment the Karoo gazania is found to grow with a variety of species such as Berkheya glabrata, Sparaxis pillansii, Heliophila spp., Lampranthus haworthii, Drosanthemum latipetaluma, Dimorphotheca sinuata, Cotula barbata, and Senecio cakeiliefolius.
