Temperature requirements
This plant is native to areas with a Mediterranean climate type, where summers are dry and hot and winters are mild and wet. Therefore, it can tolerate a wide range of temperatures, from 20-30°C (68-86°F) during the day and 10-15°C (50-59°F) at night. However, it may not tolerate extreme heat or cold, so avoid planting it in areas with harsh climates.
Soil requirements
Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa prefers well-draining soils with rich organic matter. It can grow in a variety of soil types, including sandy loam, clay, and rocky soils. However, it does not perform well in waterlogged or compacted soils. The ideal soil pH ranges from neutral (around 7) to slightly acidic (around 6).
Cultivation methods
Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa grows well in moist soil and thrives in partial shade. It is adaptable to various soil types, but slightly acidic soils are preferred. Plant the seeds in early spring or in autumn. As the plant grows, ensure that the soil remains moist, as the plant is prone to drought stress.
Watering needs
Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa requires regular watering to keep the soil moist. Water deeply once or twice a week, depending on the climate and soil type. Avoid watering the leaves and flowers, as this can lead to fungal diseases.
Fertilization
Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa does not require heavy fertilization. Applying a light, balanced fertilizer in early spring can help promote healthy growth. Avoid using high-nitrogen fertilizers, as this can lead to an overgrowth of foliage at the expense of flowers.
Pruning

Propagation of Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa
Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa is a plant that can be propagated through different methods including:
Seed propagation
Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa produces seeds that can be collected and used to propagate new plants. The seeds should be collected from the plant in fall as they begin to ripen and drop. To propagate using seeds, the seeds should first be cleaned, and stratified by placing them in a fridge for 30 days. After stratification, they can be sown in a container filled with moist soil and covered lightly with soil. The container should be kept in a cool and shaded area, and the soil should be kept moist until the seeds germinate.
Division propagation
Division propagation involves separating parts of the plant to create new plants. This method is effective for Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa as it forms clumps. To propagate using this method, the plant clumps can be carefully lifted from the ground, and the roots can be divided with a sharp knife. The divided parts can then be planted in separate containers or in different areas of the garden.
Cuttings propagation
Propagation by cuttings involves taking a stem cutting from the plant and rooting it to produce a new plant. This method is not commonly used for Cardamine trichocarpa Hochst. ex A.Rich. subsp. trichocarpa. However, if it is necessary, cuttings should be taken in spring or early summer when the plant is actively growing. The cutting should be about 3-4 inches long, and all but the top leaves should be removed. The cutting should be planted in moist soil and kept in a cool and humid place until it roots.
