Step by step: plant daylily

Daylilies thrive in full sun or partial shade, though 'Stella de Oro' flowers most freely with at least six hours of direct sunlight daily. They tolerate a wide range of soils—loam, clay, or sandy—provided drainage is reasonable. Heavy clay benefits from the addition of grit or well-rotted compost to improve structure, while very sandy soils appreciate organic matter to help retain moisture. Plant bare-root divisions or potted daylilies in March, April, or May for establishment before summer, or in September and October so roots settle in before winter. Dig a hole roughly twice the width of the root ball and deep enough that the crown (where roots meet foliage) sits just at or slightly below soil level—burying it too deeply can inhibit flowering. Space plants 45 cm apart to allow for their mature spread of 40–60 cm. If planting bare roots, spread the roots out in the hole and backfill with soil, firming gently to eliminate air pockets. For container-grown plants, tease out any circling roots before positioning. Water thoroughly immediately after planting to settle the soil around the roots and eliminate any remaining air gaps. Apply a 5 cm layer of garden compost or well-rotted manure as mulch around the base, keeping it a few centimetres clear of the crown to prevent rot. This conserves moisture, suppresses weeds, and feeds the soil as it breaks down. Daylilies establish quickly and typically don't require staking, even in exposed sites, as their clumps are sturdy and self-supporting once mature.
