Growing notes

Light

Full sun or light part shade, best with the flowers in sun and the roots in shade. In too little light the stems grow weak.

Soil

Rich, well-drained soil that stays moist; pH 6.0–7.0, while Oriental lilies need acid soil. Heavy clay and waterlogged ground rot the bulbs; on heavy soil plant in a raised bed.

Care

Plant bulbs 10–15 cm deep and 15–30 cm apart; Madonna lily (Lilium candidum) goes in with its tip just below the surface. Mulch to keep the roots cool and keep the soil moist, never waterlogged. From when the shoots appear, feed lightly once a month with a low-nitrogen fertiliser such as 5-10-10. Stake tall stems. Cut off faded flowers so no seed pods form, but leave the stem and leaves until they turn yellow. Watch for lily beetle.
