To propagate purple fountain grass, it is best to do so when the plant is going dormant. This usually occurs in late fall or early winter. Start by preparing yourself with clean, sharp cutting tools such as pruners or a knife.
1. Dig up the plant: Carefully dig up the purple fountain grass plant, making sure to include as much of the root system as possible. Gently shake off any excess soil to get a clear view of the plant’s structure.
2. Divide the plant: Examine the plant and look for natural divisions or sections that can be separated. If the plant is small, you may only need to divide it into two sections. For larger plants, you can create more divisions. Each section should have healthy roots and leaves.
3. Remove rotten or dead plant matter: While dividing the plant, be sure to inspect the roots and leaves for any signs of rot or decay. Remove any unhealthy portions, as they can hinder the growth of the new divisions.
4. Replant immediately: Once you have divided the plant, it is crucial to replant the sections as soon as possible. Choose suitable planting locations that receive adequate sunlight and have well-draining soil. Dig holes slightly larger than the root ball of each division.
5. Planting depth: Place each section into its respective hole, ensuring that the top of the root ball is level with the soil surface. Gently backfill the holes with soil and lightly tamp it down to remove any air pockets.
6. Watering: After planting, give the newly divided purple fountain grass a thorough watering to help settle the soil and provide moisture to the roots. Keep the soil consistently moist, but not waterlogged, during the establishment period.
7. Care and maintenance: Purple fountain grass is a relatively low-maintenance plant. Regularly water the divisions to keep the soil moist, especially during the first few weeks. Once established, the plant is somewhat drought tolerant and requires less frequent watering.
8. Mulching: Applying a layer of organic mulch around the base of the plants can help retain moisture, suppress weed growth, and insulate the roots during colder months. However, be careful not to bury the crown of the plant, as this can lead to rot.
9. Winter protection: In areas with cold winters, it is advisable to provide some winter protection for newly propagated divisions. You can cover the plants with a layer of mulch or use burlap to shield them from freezing temperatures.
10. Monitoring and growth: Regularly monitor the newly propagated divisions for signs of growth. Within a few weeks to a couple of months, you should start to see new shoots emerging from the divisions. Once the divisions have established themselves and are actively growing, you can treat them like mature purple fountain grass plants.
Remember to be patient with the newly divided divisions as they settle into their new homes. With proper care, they will grow and thrive, adding beauty to your garden or landscape.
