Designing with Decorative Grasses
Incorporating ornamental grasses into your landscape can create stunning visual effects and transform your garden into a multi-dimensional space. Here are some tips on how to design with decorative grasses:
Layering and Grouping
Consider planting grasses in groups for a more dramatic effect. Taller grasses can be placed at the back of a border, while shorter varieties can fill the front. This layering technique creates depth and visual interest.
Combining with Other Plants
Mixing grasses with flowering perennials and shrubs can create an eclectic garden. The movement of the grasses complements the blooms and adds a soft texture to the overall design.
Maintenance Tips for Decorative Grasses
Watering
Most decorative grasses are drought-tolerant once established, but during their initial growth, they require consistent watering. Aim for deep, infrequent watering to encourage deep root growth.
Pruning and Cutting Back
In early spring, cut back ornamental grasses to encourage new growth. This helps remove any dead foliage from the previous season.
Fertilizing
A light application of fertilizer in spring can boost growth, but be cautious not to over-fertilize, as this can lead to leggy growth.
