When to plant Hardy Geranium Rozanne?

Geranium 'Rozanne' thrives in full sun or partial shade, making it adaptable to most garden positions. It performs best with morning sun and light afternoon shade in warmer spots, though it will flower profusely in full sun if the soil retains moisture. This hardy geranium tolerates a wide range of soil types—loam, clay, or sandy—provided drainage is reasonable. Avoid waterlogged ground, but don't worry about achieving perfect conditions; 'Rozanne' is famously forgiving. Plant in March, April, September, or October when the soil is workable and temperatures are mild. Dig a hole roughly twice the width of the root ball and the same depth. Loosen the soil at the base to encourage roots to spread. Set the plant so the crown sits level with the surrounding soil—planting too deep can lead to rot. Space plants 60 cm apart; 'Rozanne' spreads vigorously to 60–90 cm, so give it room to sprawl without smothering neighbours. Backfill with the excavated soil, firming gently to eliminate air pockets. Water thoroughly after planting to settle the roots, even if the soil feels damp. A 5 cm layer of organic mulch—garden compost or well-rotted manure—around the base helps retain moisture and suppress weeds, but keep it clear of the crown itself. If planting in autumn, mulch will also provide a little extra insulation over the first winter, though 'Rozanne' is reliably hardy to zone 5a. No staking is needed; the stems are self-supporting and form a low, spreading mound.
