For the genus swainsona, well-draining soil is essential; a sunny position ensures healthy growth, while regular watering fosters establishment, tapering as plants mature. Begin by amending soil with organic matter. Plant swainsona at the same depth they were in pots, spacing them appropriately. Water thoroughly after planting and mulch to conserve moisture. While general guidelines apply, specific swainsona species may require tailored care; always verify individual needs for optimal growth.
