ðą How to Care for Loosestrife to Prevent Grey Mould?
ð§ How to Water
Keep soil consistently moist; most Lysimachia species tolerate or prefer wet conditions. Water every 3â5 days during the growing season, more frequently in hot weather. Avoid letting soil dry out completely. Ground-cover species like creeping Jenny may tolerate brief dry spells once established.
âïļ Lighting
Most Lysimachia species prefer full sun to partial shade (4â6 hours of direct light daily). Upright border types such as L. punctata perform best in full sun. Creeping varieties like L. nummularia tolerate more shade and are ideal for underplanting or woodland edges.
ðŠī Ideal Soil
Lysimachia thrives in loamy, moisture-retentive soils enriched with organic matter. A slightly acidic to neutral pH of 5.5â7.0 is ideal. Good drainage is important even for moisture-loving species to prevent root rot; avoid waterlogged clay soils.
