ðą How to Care for Sea Lyme Grass to Prevent Aphids?
ð§ How to Water
Sea lyme grass is extremely drought-tolerant and only requires occasional watering every 14 days once established. Avoid waterlogging, as the plant prefers well-drained soils. Water regularly during the initial growth phase until the plant is well-rooted.

The ideal location is full sun to partial shade. At least 6 hours of direct sunlight daily promotes vigorous growth and the intense blue-gray coloration of the foliage. The plant does not grow well in full shade.
ðŠī Ideal Soil
Sandy, nutrient-poor, and well-drained soil with a pH value between 5.5 and 8.5 is preferred. However, sea lyme grass also grows in loamy and clayey soils, though it is less aggressive in its spread there. It tolerates saline soils and coastal locations.
