Boreal Bog Sedge

Carex magellanica subsp. irrigua

Boreal Bog Sedge (Carex magellanica subsp. irrigua) is an evergreen plant from the Cyperaceae family. It is mostly found in North Eastern parts of North America, typically in wet habitats. The perennial has an upright or prostrate habit and produces long, thin stalks that are often dark green in color. These stalks bear attractive triangular-shaped leaves. This species is dioecious, meaning male and female flowers are found in separate plants, with the latter producing small, nut-like fruits in autumn. Its tolerance to moist and acidic soil makes it an excellent choice for boggy areas and help to prevent erosion.

watering

Watering: Water regularly during hot, dry weather. In summer, water at least once a week and increase the frequency of watering during extra hot or dry periods. In spring and autumn, water every 2 weeks. During the winter, there is no need to water at all, as the plant dies back and does not require water. Amount: When watering, always water deeply to a depth of around 8-10 inches. This will ensure that the water reaches the root system and not just the surface. The quantity of water will vary depending on the size of the plant and on the type of soil it is planted in. Generally, it is recommended to use around 13 gallons of water for every foot of soil.

sunlight

Large Headed Sedge (Carex macrocephala) requires approximately 6 hours of direct sunlight each day. While direct sunlight is preferable, a slightly shady area will still be beneficial for this species. A light that is too strong can cause the plant to become damaged and may even negatively impede on the flowering of the sedge. To ensure that the Large Headed Sedge receives the right balance of direct and indirect light, it should only be in full sunlight during the morning and early afternoon hours.

pruning

Large Headed Sedge can be pruned in early spring, just before new growth. Pruning consists of cutting the stems back to their base, close to the ground. Removing spent flower stems and dead or damaged foliage also helps encourage healthy growth. Prune as much as needed to keep the plant shape but be careful not to prune too much as this could cause stunted growth. Pruning once annually, in early spring, is usually sufficient to maintain a healthy and attractive Large Headed Sedge.
