The Ultimate Guide to Dividing Ornamental Grasses
For gardening enthusiasts, discovering that the center of your ornamental grass is dying isn’t a disaster; it’s an opportunity! Dividing ornamental grasses not only rejuvenates the plants but also allows you to multiply your favorites without any additional cost. With the right timing, some physical effort, and strategic moves, you can ensure your ornamental grasses thrive for years to come.
Timing is Everything: When to Divide
The secret to successful grass division lies in its timing. Recognizing the early signs of new green growth marks the perfect moment to divide your grasses. Typically, warm-season varieties such as blue stem and switchgrass thrive when divided from mid-spring through early summer, while cool-season grasses, like blue fescue, should be split in early spring or fall. Evergreen varieties, including mondo grass, are best divided late winter or early spring, ensuring robust growth and vigor.
The Benefits of Regular Division
Every seasoned gardener knows that most ornamental grasses benefit from division every 3-4 years. Delaying this task can lead to overcrowded conditions, where plants struggle for space and nutrients. As Bala Dommeti from Pixie Gardens advises, “Grasses don’t like tight spaces.” Providing ample room for root growth is essential for their health and growth; after all, just like in housing, a little space can go a long way.
Essential Tools and Safety Measures
Before diving into the division process, it's crucial to gather the right tools: safety gloves, goggles, a hedge trimmer, a sharp spade, and a mattock. As with any hands-on gardening task, safety should always come first—especially as grass blades can be sharp. The estimated costs for tools may range between $150 to $225 depending on what you need.
Steps to Successfully Divide Ornamental Grasses
Following a structured approach will yield the best results. Here's a breakdown of the key steps:
- Step 1: Prepare – Water your grass heavily a day or two before diving in. This softens the soil and helps keep the roots moist during the process.
- Step 2: Cut Back – If you haven't trimmed the grass in the fall, now is the time to cut it back to about 3-6 inches above ground, making the job easier.
- Step 3: Digging Out – Using a sharp spade or shovel, carefully dig out the clump of grass. Don’t hesitate to cut through roots—most grasses can recover from this.
- Step 4: Splitting the Roots – You can split the clump using a sharp spade or even tow forks back-to-back to pry them apart.
- Step 5: Replanting – Ideally, replant the divisions within 2-3 days to ensure the roots establish quickly.
- Step 6: Care After Division – Water apropriately and consider mulching, but ensure you do not pile mulch too closely to prevent rot.
Common Misconceptions in Grass Division
Many gardeners mistakenly assume that all ornamental grasses require the same division timing or method. As referenced by RHS guidelines, grasping the unique needs of each grass category—cool and warm climate varieties—is essential for success. Ignoring these differences may lead to subpar results or stunted growth.
Future Trends in Ornamental Grass Care
As interest in sustainable gardening grows, so does the significance of maintaining healthy ornamental grasses. Effective division reduces plant congestion and can ultimately improve air circulation, potentially mitigating diseases, such as rust. Moreover, community gardening initiatives are increasingly promoting shared gardening practices that encourage division and sharing of plants among neighbors.
