Timing
The ideal timeframe for pruning and dividing ornamental grasses falls between late winter and early spring. This period is essential as it aligns with the natural growth cycle of these plants, allowing them to flourish once the warmer weather sets in.
Purpose
Pruning and dividing ornamental grasses serve multiple purposes. Primarily, it prepares the grasses for robust growth, ensuring they have adequate space and resources to thrive. Furthermore, this practice creates transplants that can be used to enhance other areas of the landscape, while simultaneously maintaining the visual aesthetics of the garden.
Benefits of Leaving Grasses
While pruning is beneficial, leaving ornamental grasses intact through the winter months provides significant advantages. They offer winter interest, adding texture and colour to the garden even in the colder seasons. Additionally, these grasses serve as a protective habitat for wildlife, providing essential nesting material for birds and shelter for small creatures.
Signs of Need for Pruning

Method
The recommended method for pruning ornamental grasses involves cutting them back to ground level. However, it is advisable to retain some of the old growth. This not only protects the new shoots that will emerge but also contributes to the overall interest in the landscape.
Cutting Depths
When it comes to cutting depths, there are specific guidelines to follow. For small grasses, a few inches is sufficient. Conversely, larger grasses should be cut back to a depth of 4 to 6 inches to ensure a healthy regrowth.
Tools
Utilising the right tools is crucial for effective pruning. Electric hedge trimmers are recommended for their efficiency in tackling larger patches. For smaller mounds, hedge shears are ideal, while a chainsaw may be necessary for large, thick grasses. Selecting the appropriate tool can make the process smoother and more efficient.
Dividing Clumps
Dividing clumps of ornamental grasses is a vital task that should be undertaken every 3 to 5 years. This not only promotes the health of the plants but also generates new ones, contributing to the overall vitality of the landscape.
Procedure for Dividing
To effectively divide ornamental grasses, the entire root ball must be dug up carefully. It is important to remove the dead centre of the clump while retaining the outer growth, which can then be replanted to establish new plants in different areas of the garden.
Creating New Plants
When creating new plants from divided clumps, it is essential to use sharp tools to ensure clean cuts. This practice prevents damage to the plants and promotes quicker recovery. Interestingly, these new plants can be planted directly into the soil without the need for any amendments or fertilizers, making the process straightforward and efficient.
Maintenance
Ornamental grasses are known for their low maintenance requirements, making them an excellent choice for enhancing landscapes. Their resilience and adaptability allow them to thrive with minimal intervention, providing beauty and structure to gardens.
Create your stunning garden
Incorporating ornamental grasses into your garden design brings lasting beauty with minimal effort. By following the simple steps of pruning and dividing, you ensure these versatile plants remain healthy, vibrant, and an enduring part of your landscape. Whether adding winter interest or providing shelter for wildlife, ornamental grasses prove their value year-round. With the right timing, tools, and techniques, you’ll enjoy the rewards of a lush, thriving garden that requires little maintenance but offers maximum impact.
