How to care for your Acorus Ogon
- Sun and shade: Prefers full sun. However, in hot, dry regions, it’s best to provide some afternoon shade to protect the plant from scorching.
- Soil: Prefers moist, well-drained soil that is rich in organic matter. It can tolerate wet soil, making it an excellent choice for planting near water features or in boggy areas.
- Watering: Water the plant regularly, especially during periods of drought. However, be sure not to overwater as this can lead to root rot. Water the plant at the base, rather than from above, to prevent the foliage from getting wet, which can cause fungal diseases.
- Fertiliser: Does not require heavy fertilisation. A light application of balanced fertiliser in the early Spring should be sufficient to encourage healthy growth and foliage.
- Mulching: Mulch around the base of the plant to help retain moisture in the soil and suppress weed growth. This will also help to protect the plant from extreme temperatures.
- Pruning: Trim any damaged or discolored foliage regularly to encourage new growth and maintain the plant’s overall health and appearance. However, avoid cutting back more than one-third of the plant at once, as this can cause stress and reduce vigour.
- Propagation: Can be propagated by division in the Spring or Autumn. Simply dig up the plant, separate the clumps, and replant in a well-prepared soil.
By following these basic care guidelines, you can help to ensure that your Acorus Ogon remains healthy, vibrant, and glowing year after year.
