Berkeley Sedge Carex divulsa
ABOUT
Carex divulsa, commonly known as Berkeley sedge, is a lush, clump-forming perennial grass-like plant. This species boasts slender, arching, bright green leaves which give the plant a cascading, feathery appearance. The foliage texture is fine, contributing to its dense and tufted look. The leaves emerge from a central point at the base, which allows the blades to spread out gracefully in all directions, presenting an overall fountain-like shape. During its flowering period, Berkeley sedge produces inconspicuous brown flower spikes that blend in with the greenery. These spikes give way to small seed capsules as the season progresses. The plant's subtle blooms are often overshadowed by its vibrant green foliage, which remains visually appealing throughout the growing season. Overall, the Berkeley sedge has a natural and unassuming aesthetic that can easily blend into various garden styles, from formal borders to informal, naturalized areas.

WaterThe Berkeley Sedge (Carex divulsa) should be watered deeply but infrequently to encourage a strong root system. For young plants, watering twice a week may be necessary, while established plants prefer drier conditions and should be watered every other week, depending on climate and soil type. Use approximately 1 gallon of water per plant for each watering session to ensure the moisture reaches deep into the soil. During hot, dry spells, you may need to water more frequently, but always allow the soil to dry out slightly between waterings. Over-watering can lead to root rot, so it's important to assess soil moisture before watering.
LightBerkeley Sedge thrives in a variety of light conditions, from full sun to partial shade. It is best suited to spots that receive morning sun and afternoon shade or dappled sunlight throughout the day. Avoid planting it in deep shade, as this can reduce the plant's vigor and density.
TemperatureBerkeley Sedge is hardy and tolerates a wide range of temperatures, thriving best between 60°F and 75°F. It can survive minimum temperatures down to about 0°F, making it suitable for many temperate climates. Protecting the plant from extreme heat or cold is advisable to maintain its health and appearance.
PruningPruning Berkeley Sedge is beneficial for removing old foliage and encouraging fresh growth. Trim back dead or brown leaves in early spring before new growth starts. This plant does not require frequent pruning; an annual tidy-up to remove spent leaves is usually enough. The best time for pruning is late winter or early spring.
CleaningAs needed
SoilThe best soil mix for Berkeley sedge (Carex divulsa) is well-draining, fertile, and loamy with the ability to maintain slight moisture. It should ideally have a pH between 5.5 and 7.5. A mixture composed of garden soil, compost, and perlite or sand would serve as an excellent medium for this plant's growth.
RepottingBerkeley sedge (Carex divulsa) does not require frequent repotting and typically can be repotted every two to three years. The main reason to repot would be to divide the plant to manage its size and rejuvenate its growth.
Humidity & MistingBerkeley sedge (Carex divulsa) prefers moderate humidity levels but is quite adaptable and can tolerate a range of humidity conditions. There is no specific humidity requirement, but ensuring good air circulation helps in maintaining its health.
Suitable locationsIndoor
Place Berkeley sedge in bright, indirect light with well-draining soil.
Outdoor
Plant Berkeley sedge in part shade to full sun with moist soil.

Life cycleThe life of Carex divulsa, commonly known as Grey Sedge, begins with seed germination, which occurs in moist soil conditions often in spring. The seedlings develop into clumps of grass-like foliage, featuring narrow leaves that are rolled inward at the bud stage, a characteristic trait of sedges. As the plant matures, it develops a dense root system and flowering stems called culms that rise above the foliage in late spring to early summer. The flowers of Grey Sedge are wind-pollinated and are not showy, comprising of small, greenish-brown spikelets. After pollination, the plant produces fruits called perigynia, which house the seeds that will disperse to produce new plants. In the autumn, the plant may die back slightly but as a perennial, it survives through the winter and resumes growth the following spring.
PropogationPropogation time
Spring to summer
The most popular method of propagating Carex divulsa, commonly known as Berkeley sedge, is through division. This technique is typically undertaken in late winter to early spring before new growth begins. To propagate by division, one would carefully dig up an established clump of Berkeley sedge, ensuring to keep a good portion of the root system intact with each division. The clump should then be gently separated into smaller sections, each with several growing points. These individual sections can then be replanted immediately in well-draining soil at the same depth they were growing originally. It is important to water the new divisions thoroughly after planting to help establish the roots. With proper care, these new plants will start to grow and establish themselves over the following growing season.
