It belongs to the family of Aspleniaceae, and it is commonly known as pineland spleenwort or narrow-leaved spleenwort. It is native to various parts of Europe and North Africa, but it is also found in some parts of North America and Asia.
Light Requirements
The plant prefers partial to full shade conditions and cannot tolerate excessive exposure to direct sunlight. Therefore, it thrives in areas under the canopy of trees or in places where it receives dappled sunlight. It can also be grown successfully in areas with artificial shade covers.
Temperature Requirements
Aspalthium herbaceum Medik. prefers moderate temperatures that range between 15°C and 25°C. However, it can tolerate a wide range of temperatures, as long as they do not fluctuate significantly. Extreme temperatures can cause stunted growth or damage to the plant.
Soil Requirements
The plant requires well-drained soil that is rich in organic matter. The soil should have a slightly acidic to neutral pH (6.0 – 7.0). Aspalthium herbaceum Medik. prefers soil with good moisture retention but not waterlogged conditions. It can also tolerate a wide range of soil textures, including sandy soils and loamy soils.
Cultivation Methods
Aspalthium herbaceum Medik. is commonly known as Prickly Restharrow, and it belongs to the Fabaceae family. This plant is best grown in well-drained sandy soil under full sun exposure. It has a spreading habit and does not require much space between plants. Propagation can be done through seeds or by dividing the roots of mature plants in early spring or late fall.
Watering Needs
Aspalthium herbaceum Medik. has moderate water requirements and can tolerate short periods of drought. It is advisable to water the plant once a week during the growing season or when the top inch of the soil feels dry to the touch. Overwatering can cause the roots to rot, and proper drainage is crucial.
Fertilization
Aspalthium herbaceum Medik. does not require much fertilization, but adding compost or well-rotted manure before planting can improve the soil structure and provide essential nutrients. During the growing season, a balanced fertilizer with an NPK ratio of 10-10-10 can be applied once a month. However, too much nitrogen can cause excessive vegetative growth and reduce flowering.
Pruning
Aspalthium herbaceum Medik. requires little pruning except for removing dead or damaged stems. The plant has spiny stems, and it is advisable to use gloves when handling it. Pruning can be done after flowering or in late winter or early spring before new growth. Over-pruning can reduce flowering, and it is advisable to maintain the natural shape of the plant.
Propagation of Aspalthium herbaceum Medik.
Aspalthium herbaceum Medik., commonly known as soft shield fern, can be propagated through various methods. Here are some propagation methods:
Spores
Propagation of Aspalthium herbaceum Medik. through spores is a time-consuming process but is the most natural way to propagate the plant. Spores can be collected from the fronds and sowed in a well-drained potting mix. The pot should be kept in a warm, humid environment until the spores germinate and grow into young plants.
Division
Division is the most common way to propagate Aspalthium herbaceum Medik. This method is best done during the plant's active growth period, which is in spring or early autumn. The plant can be carefully dug up, and the roots can be gently teased apart into smaller sections. Each division should have several fronds and a few healthy roots. The divisions can be planted in a well-drained soil mix and kept moist until they establish.
Offsets
Offsets are small plantlets that grow at the base of the parent plant. They can be gently detached from the parent plant and planted in a well-drained potting mix. The pot can be kept in a warm, humid environment until the offsets establish roots and grow into young plants.
Cuttings
Cuttings can be taken from the rhizome of Aspalthium herbaceum Medik. Cuttings should be taken during the summer when the plant is actively growing. The rhizome should be cut into sections, and each section should have a bud and some roots. The cuttings can be planted in a potting mix and kept moist until they establish.
Disease and Pest Management for Aspalthium herbaceum Medik.

- Slugs and snails: These pests can feed on the leaves and stems of the plant, causing damage and potentially killing the plant.
- Aphids: These tiny insects can suck the sap out of the plant, causing leaves to curl and yellow. They can also transmit plant viruses.
Managing Diseases and Pests
To manage fungal diseases, it is important to remove any infected material and dispose of it carefully. Avoid watering the plant from above, as this can help to reduce the risk of leaf spot and powdery mildew. Additionally, you can use fungicides to manage fungal diseases, but be sure to follow the instructions carefully and use them sparingly.
To manage slugs and snails, you can use physical barriers, such as copper tape or eggshells, around the plant to deter them. You can also use slug pellets, but avoid using these near food crops. To manage aphids, you can use insecticidal soap or neem oil to kill the insects.
Overall, Aspalthium herbaceum Medik. is a relatively low maintenance plant. By promoting good growing conditions and taking steps to manage common pests and diseases, you can help to ensure that your plant thrives and stays healthy.
