How to Divide Large Overgrown Ornamental Grasses: To keep large, overgrown ornamental grasses healthy, attractive, and to encourage vigourous development, dividing them is an essential gardening activity. Here’s a detailed tutorial on splitting these plants successfully:
Select the Appropriate Moment
When ornamental grasses are dormant, which is usually in late winter or early spring before new growth begins, this is the ideal time to divide them. This time frame enables the plant to recuperate and establish itself prior to the start of the growing season.
Fall is a good time to divide grasses that grow in warm climates. Steer clear of splitting the plant in the height of summer or the winter, when it is stressed or dormant, respectively.

Set Up Your Space and Tools
Assemble the following equipment: gloves, pruning shears, a garden knife or saw, and a sharp spade or garden fork. Make sure the space is ready for work by removing any mulch or rubbish. Having compost or a balanced fertiliser on hand is also a good idea for amending the soil following division.
Fill the Well with Grass
Water the grass well a day or two before you intend to divide it. This facilitates the lifting of the clump by softening the soil. Additionally, it lessens plant stress, which facilitates a more seamless division process.
Undredge the Grass
With a garden fork or spade, carefully excavate the area surrounding the grass clump. To reduce root damage, try to get as much as you can under the root ball. Take the clump out of the ground gently and shake off any excess soil. To lift a particularly huge or heavy clump, you may need help or a garden cart.
Split the Bulge
After the clump is out of the earth, split it into smaller pieces with a sharp knife, saw, or shovel. There should be a good amount of roots and leaves in every region.
It is manageable for many grasses to split the clump into portions that are between 6 and 12 inches in diameter. Depending on the size of the clump and the plant’s vigour, aim for 3–4 sections.
Clean and Trim
Once divided, give each section a trim to remove any overgrowth. This lessens the amount of water required by the plant as it forms new roots. Eliminate any unhealthy or damaged roots and dispose of any dead or infected clump parts. Replanting only the healthiest portions of the plant is ensured by this process.
Treat and Replant
To prevent drying out, immediately replant the separated pieces. Select a spot that satisfies the soil and light needs of the plant. Create a hole that is big enough to hold the separated parts’ roots. After gently spreading out the roots, place each part in the hole.
Fill in the hole with soil, gently compacting it around the plant. After planting, give the soil a thorough watering to assist settle and remove any air pockets.
Water and Mulch
Mulch the area beneath the recently planted parts to help control temperature and hold in soil moisture. To aid in the plants’ root establishment, keep giving them regular watering, especially in the first few weeks. Take care not to overwater since this can cause rot in the roots.
Keep an eye on it
Once they settle in, keep a watch on the segregated sections. Keep an eye out for symptoms of stress like withering or discoloured foliage. As necessary, modify care and watering to promote healthy growth. Check for illnesses and pests on a regular basis, and add more compost or mulch as needed.
Final Thoughts
Large, overgrown decorative grasses can be divided to revitalise your yard and guarantee that these plants keep growing. You may successfully manage and propagate your decorative grasses by following these steps timing your planting, getting your equipment ready, watering beforehand, dividing and replanting your grasses carefully, and providing the necessary care.
This approach not only makes your garden seem better, but it also encourages strong, healthy development in the coming seasons.
