When cultivating Carex lucorum, it is essential to ensure that the soil is kept moist at all times. It is also important to avoid exposing the plant to direct sunlight because it thrives in partial to full shade. It is best to plant Carex lucorum in the spring, after the last frost.
Watering Needs
As noted earlier, Carex lucorum requires moist soil to grow healthy. Depending on your geographical location, you might need to water your plants frequently during the dry season. However, it is important to avoid overwatering because it might lead to root rot. A good indicator that your plant needs watering is when the topsoil feels dry to the touch.
Fertilization
Carex lucorum is not a heavy feeder, and it does not require a lot of fertilization. However, to ensure that it grows healthy, you can apply a slow-release fertilizer during the spring. Alternatively, you can always choose to apply compost to the soil around the plant to give it the required nutrients.
Pruning

Since it grows up to 60cm, you might also want to cut it back after the flowering season to prevent it from getting too large. Prune the plant in the fall before the winter sets in.
Propagation of Carex lucorum Willd. ex Link var. lucorum
Carex lucorum Willd. ex Link var. lucorum can be propagated through both seeds and division.
Propagating through Seeds:
Seeds of Carex lucorum Willd. ex Link var. lucorum can be sown directly in the ground (or in pots) in spring or fall, depending on the geographic location. It is important to provide moist soil conditions and to keep the seeds at a cooler temperature during the germination period. The germination period can last from a few weeks to several months, depending on the conditions provided.
Propagating through Division:
Division is the most common propagation method for Carex lucorum Willd. ex Link var. lucorum. It involves separating the plant into several smaller sections, each with its own set of roots and foliage. Division is best done in early spring, just before the plant enters its active growth stage. Lift the plant carefully from the ground using a spade or fork, then separate the plant into sections using a sharp knife. The sections should be planted in soil that is moist, well-draining, and with similar conditions to where it was previously planted.
Once propagated, it is important to provide the necessary care for the plant to establish properly and thrive. Adequate watering and fertilization are necessary, as well as providing the right amount of sun and shade depending on the plant's preferences.
Disease Management
Just like any other plant, Carex lucorum is susceptible to various diseases. Some of the most common diseases that may affect the plant include leaf blight, smut, rust, and anthracnose, among others. Preventive measures are the best approach to managing diseases. Thus, it is important to ensure that the plant is well-watered, appropriately fertilized, and exposed to the right amount of sunlight. Additionally, regular pruning, especially of dead or infected areas, is crucial in prevention. In case of an infection, use of fungicides can help to stop the spread of the disease.
Pest Management
Carex lucorum can also be vulnerable to pest attacks. Some of the common pests include aphids, spider mites, mealybugs, and slugs, among others. Prevention is also crucial in pest management and can be achieved by ensuring a healthy plant by providing adequate nutrients, water, and sunlight. Additionally, avoiding over-fertilization, which can encourage pest breeding, is important. Handpicking of pests can help to manage the infestation. In severe infestations, the use of insecticides can be applied, but it should be done with caution to avoid damage of the plant.
