Light Requirements
Matthiola longipetala subsp. livida requires full sun exposure for optimal growth. It thrives in areas where it receives at least 6-8 hours of direct sunlight per day. Insufficient sunlight exposure may result in stunted growth and reduced flower production.
Temperature Requirements
This plant is a cool-season crop that grows best in temperatures between 50-70°F (10-21°C). High temperatures can induce early flowering and reduce the overall size of the plant. It is important to protect the plant from extreme temperature fluctuations as it is relatively sensitive to heat stress.
Soil Requirements
The ideal soil for Matthiola longipetala subsp. livida should be well-drained, rich in organic matter, and have a slightly acidic to neutral pH level (6.0-7.0). The plant prefers a deep, fertile, and loamy soil that retains moisture but does not become waterlogged. The addition of compost or aged manure can improve soil quality and enhance the plant's growth and development.
Cultivation methods
Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire prefers well-drained soils and plenty of sunlight. It grows best in full sun, but it can tolerate some shade. The plant should be spaced at least 6 inches apart to give each one enough room to grow. If the soil is too clayey, add compost or sand to improve drainage.
Watering needs
The plant requires regular watering, and the soil should never dry out completely. However, be careful not to overwater the Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire, as the roots may rot if the soil is too wet. Water the plant deeply once a week, and make sure the top inch of soil is moist. In extremely hot or dry conditions, water the plant more frequently.
Fertilization
Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire benefits from regular fertilization to promote healthy growth and flowering. Use a balanced, general-purpose fertilizer every four to six weeks during the growing season. Follow the instructions on the package, and be careful not to overfeed the plant, as this can damage the roots.
Pruning
The Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire does not require much pruning. However, you can pinch back the tips of the plant when it is about 6 inches tall to encourage it to branch out and produce more flowers. You can also deadhead the spent flowers to promote new growth and extend the blooming period.
Propagation of Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire
Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire, commonly known as Night-scented Stock or Evening-scented Stock, is propagated through seeds. Propagation through cuttings and division is not a common practice for this species. The following are the propagation methods used for Night-scented Stock.
Seed Propagation
Seeds for Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire can be collected from the plant itself or purchased from nurseries. The best time to collect seeds is after the seedpods have dried on the plant. Seeds can then be sown directly into the ground or in containers. The soil should be well-drained and fertile, with a pH range of 6.5-7.5. Sow the seeds at a depth of 1/16th of an inch, as the seeds require light to germinate.
Keep the soil moist by watering gently. It takes approximately 10-14 days for the seeds to germinate. Once the plants have established, they require little maintenance, except for regular watering and fertilizing. It is best to sow the seeds in the spring, once the soil warms up.
Disease Management
Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire is susceptible to various diseases. One of the most common diseases that affect this plant is fungal leaf spot disease, which is caused by the fungus Alternaria brassicicola. This disease is characterized by circular, dark brown spots on the leaves, which can cause the leaves to drop prematurely. To manage this disease, it is recommended to remove infected plant debris and avoid overhead watering.
Another prevalent disease in Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire is powdery mildew, which is caused by a fungus called Erysiphe cruciferarum. This disease is characterized by a white powdery coating on the leaves and stems, which can stunt the plant's growth and reduce its yield. To manage powdery mildew, the infected plant parts should be removed and destroyed, and the plants should be watered early in the morning to prevent the growth of the fungus.
Pest Management
In addition to diseases, pests can also damage Matthiola longipetala (Vent.) DC. subsp. livida (Delile) Maire. One of the most common pests that affect this plant is the aphid. Aphids are small insects that feed on the plant's sap, causing the leaves to curl and wither. To manage this pest, it is recommended to use natural predators such as parasitic wasps, ladybugs, and lacewings. Additionally, spraying the plants with a strong jet of water can help to dislodge the aphids.
Another pest that can damage this plant is the flea beetle. These beetles leave small, circular holes on the plant's leaves, which can cause the leaves to wilt and die. To manage flea beetles, it is recommended to use row covers to prevent the beetles from laying their eggs on the plants. Additionally, spraying the plants with a neem oil solution can help to repel the beetles.
