Light Requirement
Lathyrus lanszwertii Kellogg var. lanszwertii grows well in partial to full sun conditions. It requires at least 6 hours of direct sunlight per day for optimal growth. However, it can tolerate some shade, especially during the hottest parts of the day.
Temperature Requirement
Being a native of the Western United States, Lathyrus lanszwertii Kellogg var. lanszwertii thrives in warm weather. It grows best in temperatures ranging from 60°F to 85°F (15°C to 29°C). It can tolerate slightly lower and higher temperatures but prefers a mild climatic condition.
Soil Requirement
The plant prefers well-draining and fertile soil. It can grow in a wide range of soils, but the ideal soil condition is sandy loam or clay loam. The pH level of the soil should be neutral or slightly alkaline, ranging from 6.0 to 7.5. The plant does not tolerate waterlogged soil and hence, good drainage is essential.
Cultivation
The Lathyrus lanszwertii Kellogg var. lanszwertii, also known as Sierra pea, is relatively easy to cultivate. It is a perennial flowering plant that thrives in areas with a Mediterranean climate. Sierra pea prefers well-draining soil with a pH range of 6.2 to 7.2. The plant does well in full sun or partial shade, and the ideal temperature range is between 50 and 86°F (10 and 30°C). Ensure that the spot chosen for planting has good air circulation.
Watering Needs
The Sierra pea plant requires moderate watering, especially during the growing season. Water the plant deeply once or twice a week, depending on how quickly the soil dries out. The top 1-2 inches of soil should be dry before the next watering. To avoid waterlogging, ensure that the soil is well-draining as the plant prefers slightly dry conditions.
Fertilization
Lathyrus lanszwertii Kellogg var. lanszwertii benefits from a well-balanced fertilizer. Apply a slow-release granular or organic fertilizer during the growing season, around the base of the plant. Fertilize the plant every 2-3 months to ensure robust growth and flowering. Additionally, you could add a liquid fertilizer every two weeks for lush blooms.
Pruning
The Sierra pea plant requires little pruning, but it is advisable to maintain it. Prune off any spent blooms as soon as they wilt. This practice encourages the plant to flower more. Cut back long shoots and remove older stems from the base of the plant to create space and maintain size. You can prune the plant in late winter or early spring before the new shoots emerge.
Propagation of Lathyrus lanszwertii Kellogg var. lanszwertii
Lathyrus lanszwertii Kellogg var. lanszwertii, commonly known as Sierra pea or Sierra sweet pea, is a beautiful plant species that belongs to the Fabaceae family. Propagation of this plant can be done through various methods, including seed propagation and vegetative propagation.
Seed Propagation
Seed propagation is one of the common methods of propagating Lathyrus lanszwertii Kellogg var. lanszwertii. The plant produces seeds in a pod, which can be harvested when the pod has matured and turned brown. After harvesting, the seed can be stored in a cool and dry place before sowing.
Before sowing, the seeds should be soaked in water for some hours to help germination. After soaking, they can be sown directly in the soil or started indoors and transplanted later. Plant the seeds at a depth of about 1 inch in a well-draining soil mixture. The soil should be kept moist but not waterlogged to promote healthy growth. The plant will germinate within 7-14 days if the conditions are suitable.
Vegetative Propagation
Vegetative propagation is another method of propagating Lathyrus lanszwertii Kellogg var. lanszwertii. This method involves taking cuttings from the parent plant and then growing them to develop new plants. The cuttings should be taken from healthy, mature stems and should be about 3-4 inches long.
After taking the cuttings, remove the leaves from the lower section of the stem and dip the cut end in a rooting hormone. Plant the cuttings in a pot filled with a well-draining soil mixture, and cover with a clear plastic bag to create a humid environment. Place the pot in a warm, bright spot, but avoid direct sunlight. Within two to four weeks, the cuttings will start to root, and new growth will appear.
Once new growth appears, remove the plastic bag and transfer the plant to a larger container or transplant it outdoors. The plant should be watered regularly and provided with adequate sunlight and nutrients to support healthy growth.
Both seed propagation and vegetative propagation are excellent ways of propagating Lathyrus lanszwertii Kellogg var. lanszwertii. By following these simple steps, you can propagate this beautiful plant and add it to your garden or indoor space.
Disease Management
Lathyrus lanszwertii Kellogg var. lanszwertii is susceptible to various diseases that can compromise the plant's health and productivity.
One of the common plant diseases of sweet peas is Powdery Mildew, a fungal disease that affects young leaves and buds. To manage this disease, remove the infected plant parts and apply a fungicide. You can also grow Powdery Mildew-resistant sweet peas to prevent the disease from occurring.
Another disease that can affect lathyrus lanszwertii is Fusarium Wilt. It is a soil-borne fungal disease that causes plants to wilt and eventually die. To control this, ensure you plant in well-draining soil, rotate crops, and remove the infected plants.
Stem Rot is also a disease that can affect the plant and cause stem degradation and loss of leaves. Proper plant sanitation practices and maintaining plant health through proper plant nutrition can prevent stem rot from occurring.
Pest Management
Lathyrus lanszwertii Kellogg var. lanszwertii is susceptible to pest infestations that can inflict considerable damage to the plant.
Aphids, for instance, are small sap-sucking insects that feed on the plant's leaves. To control this pest, introduce natural predators such as ladybugs or lacewings, or apply insecticidal soap.
Spider mites are another common pest of sweet peas, with symptoms such as leaf discoloration and webbing. To manage spider mites, increase humidity levels, prune out the infected parts, and apply insecticidal soap.
Sweet peas are also susceptible to cutworms, which feed on the stems of young seedlings and cause wilting. To manage cutworms, apply a biological pesticide or handpick and destroy the larvae.
