🌱 How to Care for Wavy-Leaf Plantain Lily to Prevent Aphids?

💧 How to Water

Water deeply once a week, increasing to twice weekly during hot spells. Allow the top inch of soil to dry slightly between waterings. Avoid wetting the foliage to reduce fungal disease risk. Reduce watering frequency as temperatures cool in autumn.

☀️ Lighting

Provide partial to full shade — morning sun with afternoon shade is ideal. Direct afternoon sun will scorch and bleach the variegated leaves. Deep shade results in less vigorous growth. Dappled light under deciduous trees is the perfect environment.

🪴 Ideal Soil

Use rich, humus-laden, well-draining soil. Amend with compost or leaf mold at planting. A slightly acidic to neutral pH of 6.0–7.5 is preferred. Avoid heavy clay or sandy soils; mulch around the base to retain moisture and suppress weeds.
