Taxonomy
Common names
Spike Rush, Canada Spikesedge, Knoblike Spikesedge, Bent SpikerushHow to care for Spike Rush
Water
Spike Rush should be watered regularly, allowing the soil to dry out between waterings.
Soil
Spike Rush loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
Spike Rush thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Knoblike Spikesedge.
