Pruning Fountain Grass
Fountain Grass, or Pennisetum, is a beautiful garden plant that adds a graceful appearance to any border. This ornamental grass is known for its playful plumes and elegant growth habit, making it a beloved border plant. To keep fountain grass in top condition, it is important to prune the plant correctly and at the right time. In this blog, you can read everything about when and how to prune fountain grass, and how to maintain it further.
When fountain grass pruning?
Pruning Fountain Grass should be done at the right time to keep the plant healthy and stimulate new growth. This ornamental grass is best pruned in early spring, usually in March or April. By waiting until the worst of the cold has passed, you prevent the plant from sustaining frost damage.
Although it may be tempting to cut off the dead leaves and plumes in the autumn, it is better not to do so. The withered leaves actually provide protection against frost during the winter months. Therefore, leave the grass alone in the autumn and only prune in the spring.
How to prune fountain grass?
Pruning fountain grass is simple, but must be done with care so as not to damage the plant. Follow these steps for a successful pruning:
1. Choose the right moment The best time to prune fountain grass is, as mentioned above, in early spring, usually in March or April. Wait until the risk of severe frost has passed so that the new shoots do not suffer damage. The old leaves and plumes offer protection against the cold in winter, so do not prune too early. 2. Use the right tools Sharp pruning shears, hedge shears, or an electric trimmer are ideal for pruning fountain grass. Ensure that the tools are clean and sharp to prevent ragged cuts and damage to the plant.
3. Trim back the Fountain Grass
Cut the grass back to about 10-15 cm above the ground. This ensures that the new shoots get enough space and light to sprout. If you leave the grass too high, the old foliage can hinder new growth.
4. Remove old leaves and plumes By removing dead leaves and old plumes, you prevent mold formation and diseases. This also stimulates healthy and fresh growth in the spring. Use gloves if necessary to protect your hands from sharp leaf edges. 5. Dispose of the pruning waste Dispose of the pruning waste in the green waste container or on the compost heap. The old leaves and stems decompose well and can serve as natural mulch or compost for other plants in your garden.
6. Provide extra care after pruning
After pruning, you can consider giving the plant a light fertilization with organic fertilizer or compost. This helps the grass grow back faster and fuller.
7. Enjoy the renewed growth
Within a few weeks, fountain grass will form new shoots and have a full, graceful appearance again in the summer. By pruning annually, the plant remains healthy and retains its beautiful shape.
With these simple but effective pruning tips, you will enjoy beautifully flowering fountain grass in your garden every year!
