Why Add Ornamental Grasses to Your Garden?

  • Elegant Aesthetics: Ornamental grasses offer a graceful and aesthetic appeal to any garden. Their flowing blades and feathery plumes add a soft, swaying element that contrasts beautifully with other plant types.
  • Low Maintenance: Compared to many other garden plants, ornamental grasses are relatively low maintenance. Once established, they are drought-tolerant and can thrive in various soil conditions, making them an ideal choice for busy gardeners.
  • Year-Round Interest: Many ornamental grasses retain their beauty throughout the seasons, even in winter. Their dried seed heads and foliage create a captivating spectacle during colder months, providing visual interest year-round.

Thompson's Top Three Ornamental Grasses

How to care for ornamental grasses?

Ornamental grasses are easy to care for with these essential tips:

  • Planting: Choose a sunny spot with well-draining soil. Plant in spring or early autumn to establish strong roots before extreme weather.
  • Watering: During their first growing season, water regularly to aid root development. Once established, most ornamental grasses are drought-tolerant, but water during extended dry spells.
  • Pruning: In late winter or early spring, cut back last year's growth to a few inches above the ground. This encourages fresh growth and keeps the grass neat.
  • Fertilizing: Ornamental grasses don't need much fertilization. Use a balanced, slow-release fertilizer in spring for a gentle boost, avoiding excessive fertilization to prevent weak growth.
  • Division: To maintain vigour and prevent overcrowding, divide overgrown clumps every few years.
