Growth Conditions of Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct.
Light: Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct. prefers full sun to partial shade. It needs at least 6 hours of direct sunlight daily for proper growth and development.
Temperature: This plant can tolerate a wide range of temperatures. However, it grows best in cool climates with temperatures between 15 to 19°C (60-66°F). The minimum temperature range for its growth is 4°C (39°F) while the maximum temperature range is up to 24°C (75°F).
Soil: Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct. prefers well-drained, deep soil that is rich in organic matter. It grows best in loamy soils with a pH range of 6.5 to 7.5. The soil should also be consistently moist but not waterlogged.
Fertilizer: These plants do not require much fertilization. However, adding compost or organic matter to the soil before planting can improve soil fertility and support the plant's growth and development.
Water: Watering frequency depends on the weather and soil type. In general, the plant needs regular and consistent watering, especially during hot and dry weather. It is important to avoid over-watering or letting the soil dry out completely.
Propagation: This plant can be propagated using seeds or stem cuttings. Seeds should be planted in moist soil, and stem cuttings taken from the parent plant should be rooted in a well-draining soil mixture.
Cultivation Methods
Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct. can tolerate a wide range of climatic conditions, from temperate to cold. It grows best in loamy, well-draining soils that are high in nutrients. The plant can be propagated from seeds, which are best sown directly in the ground in the fall or early spring.
Watering Needs
Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct. requires regular watering during the growing season. The soil should be kept moist but not waterlogged, as excessive moisture can lead to root rot. In summer months, it may need additional watering due to increased evaporation.
Fertilization
The plant needs a balanced fertilizer application during the growing season to promote growth and flowering. It is best to apply fertilizer after the soil has been moistened, as this will help prevent root burn. Regular applications of compost or well-rotted manure can also help provide the plant with the necessary nutrients it needs.
Pruning
Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct. should be pruned back after it has finished blooming for the season to help encourage bushier growth. Remove any dead or diseased wood, and prune any branches that are crossing or rubbing against each other. It is best to prune the plant during the spring or early summer months, before new growth begins to emerge.
Propagation of Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct.
Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct., also known as Alpine horseradish, can be propagated using several methods, including:
Seeds
Propagation through seeds is the most commonly used method for Lepidium armoracia. The seeds should be sown in well-drained soil, and the soil should be kept moist until germination. The seeds usually germinate within two to three weeks under optimal conditions. Once the seedling is established, it can be transplanted to a bigger pot or to the garden.
Root division
Root division is another popular method of propagating Lepidium armoracia. It is recommended to divide the plant during the dormant season, which usually occurs in fall or early spring. The root crown should be carefully dug out, and the visible buds should be separated using a sharp and sterile knife. The divided crowns can be then replanted in well-drained soil.
Cuttings
Lepidium armoracia can be propagated from cuttings, although this method is not as commonly used as the previous two. Cuttings should be taken from the plant's stem in the summer, and only the semi-hardwood cuttings should be used. The cuttings should be around 10cm long and should have mature knots. The cutting should be dipped in rooting hormone and then planted in a well-drained soil mix. The cutting should be kept in a warm and humid environment and should be irrigated and fertilized regularly.
Disease Management
Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct. is susceptible to a variety of diseases. Some of the common ones are:
- Black rot: This disease is caused by the bacteria Xanthomonas campestris. The symptoms include wilting, yellowing of leaves, and eventually blackening and rotting of roots. To manage this disease, remove infected plants, rotate crops, and avoid overhead irrigation.
- Clubroot: This disease is caused by the fungus Plasmodiophora brassicae. The symptoms include stunted growth, yellowing of leaves, and swelling of roots. To manage this disease, use pathogen-free seeds, practice crop rotation, and avoid planting in acidic soils.
- Downy mildew: This disease is caused by the fungus Peronospora parasitica. The symptoms include yellowing and wilting of leaves, and the appearance of a grayish-white mold on the undersides of leaves. To manage this disease, avoid overhead irrigation, remove infected plants, and improve air circulation.
Pest Management
Lepidium armoracia Fisch. & C.A.Mey. var. alpigenum auct. is also susceptible to various pests. Some of the common ones are:
- Aphids: These small insects feed on the sap of plants, causing stunted growth and deformities. To manage aphids, use a high-pressure water hose to wash them off, use insecticidal soap, and introduce natural predators like ladybugs.
- Cabbage worms: These caterpillars feed on the leaves of plants, causing holes and damage. To manage cabbage worms, practice crop rotation, use floating row covers to protect plants, and introduce natural predators like birds and wasps.
- Cabbage root maggots: These larvae feed on the roots of plants, causing wilt and stunted growth. To manage cabbage root maggots, use row covers, avoid overcrowding plants, and practice crop rotation.
