Why Grasses Work So Well in Sandy Soil
Ornamental grasses are perfect partners for sandy, coastal gardens. They bring movement, contrast, and structure—while thriving in the very conditions that challenge many traditional plants.
Quick Answer: Grasses like Stipa, Festuca, and Miscanthus thrive in sandy soil thanks to their deep roots, drought tolerance, and low-maintenance nature.
