Cultivation methods
Lathyrus hygrophilus Taub. var. hygrophilus can be grown in a variety of soil types, including sandy loam and clay loam. It is best to choose a location that receives ample sunshine, and well-drained soil. Make sure to plant the seeds at a depth of about one inch and keep them moist.
Watering needs
Watering is essential during the first few weeks after planting until the plant is established. After that, it is best to water the plant when the top layer of soil is dry to the touch. It is essential to avoid overwatering, which can lead to root rot.
Fertilization
Lathyrus hygrophilus Taub. var. hygrophilus grows well in soil that is rich in organic matter. Using compost or well-rotted manure is an excellent way to add nutrients to the soil. It is best to fertilize the plant in the early spring before new growth appears.
Pruning
Pruning is not necessary for Lathyrus hygrophilus Taub. var. hygrophilus, but it can help keep the plant productive and healthy. Deadheading the spent flowers can prolong the blooming season, and cutting back the plant in the late fall can encourage new growth in the spring.
Propagation Methods of Lathyrus hygrophilus Taub. var. hygrophilus
Lathyrus hygrophilus Taub. var. hygrophilus, commonly known as Marsh pea or Large marsh vetchling, is a herbaceous perennial plant that belongs to the legume family. It can be propagated using different methods such as seeds, cuttings, and division.
Propagation via Seeds
The easiest and most preferred method of propagating Lathyrus hygrophilus is via seeds. The seeds can be collected from mature pods in autumn and sown directly or stored until spring. Before sowing, it is recommended to scarify the hard seed coat or soak the seeds in warm water overnight. Germination usually takes 2-3 weeks, and the seedlings can be transplanted in early summer when they are about 10cm tall.
Propagation via Cuttings
Lathyrus hygrophilus can also be propagated through cuttings. Softwood cuttings taken in early summer from the tips of healthy, non-flowering stems can be used for propagation. The cuttings should be about 7-10cm long and inserted into a potting mix of peat and sand. They should be kept moist and placed in a shaded area until root development is observed in 2-3 weeks. The new plants can be moved to a larger container or transplanted to the garden when they are established.
Propagation via Division
Another propagation method for Lathyrus hygrophilus is through division. This can be done in the early spring before new growth appears. The plant is carefully lifted from the ground, and the rootstock is divided into smaller sections. Each section should have at least one healthy shoot and root system. The divided plants are then transplanted to a new location in the garden or a container with the appropriate potting mix.
Regardless of the method used, ensuring that the plants receive adequate water and light is crucial for their survival and growth.
