Light Requirements
Trichostema dichotomum L. var. puberulum Fern. & Grisc. thrives well in full sun exposure. It requires a minimum of six hours of direct sunlight per day. The plant's leaves are adapted to withstand high light intensity, and it usually grows on exposed rocky slopes and ridges with minimal shading.
Temperature Requirements
The plant can withstand moderate temperature variation. Trichostema dichotomum L. var. puberulum Fern. & Grisc. prefers warm temperatures ranging from 15°C to 30°C during its growth cycle. The minimum temperature at which the plant can grow is 5°C, and it usually goes dormant during the winter season.
Soil Requirements
Trichostema dichotomum L. var. puberulum Fern. & Grisc. prefers well-draining soils with a pH range of 6.0 to 7.5. Sandy loam to gravelly soils with good aeration is the best for the plant's growth. It also requires occasional watering to achieve the necessary moisture content in the ground. The plant generally does well in areas with low soil fertility.
Cultivation of Trichostema dichotomum L. var. puberulum Fern. & Grisc.
Trichostema dichotomum L. var. puberulum Fern. & Grisc. is an attractive native plant commonly found in dry areas, rocky slopes, and hillsides of California. It does well in coastal sage scrub and chaparral communities and requires minimal care and maintenance.
These plants can be propagated through seeds, which can be collected from the plant during fall or purchased from nurseries. The seeds need to be stratified for two months before planting in sandy soil. Planting should take place in spring, after the last frost.
Watering Needs
Trichostema dichotomum L. var. puberulum Fern. & Grisc. is drought tolerant and does well in well-drained soils. Young plants need regular watering to allow them to establish their roots. Once established, these plants can go for extended periods without water, making them ideal for xeriscaping.
In areas with extended drought periods, occasional deep watering is recommended to keep the plants from drying out. Watering should be done early in the mornings or late in the evenings to minimize water loss due to evaporation. Overwatering may lead to root rot, which can be fatal to the plant.
Fertilization
Trichostema dichotomum L. var. puberulum Fern. & Grisc. does not require frequent fertilization since the plants do well in nutrient-poor soils. Fertilization can be done once a year during the growing season using a slow-release nitrogen-based fertilizer. This will provide the necessary supplements to boost the plant's growth and flowering.
Pruning
Trichostema dichotomum L. var. puberulum Fern. & Grisc. requires minimal pruning to keep them looking neat and healthy. Pruning should be done in early spring before the plant begins its growth cycle. At this time, any dead or broken branches should be removed, and any overgrown stems should be cut back to promote bushier growth.
Trimming should be done with clean shears to minimize the risk of infection. Over-pruning may lead to weak and spindly growth, reducing the plant's attractiveness.
Propagation of Trichostema dichotomum L. var. puberulum Fern. & Grisc.
Trichostema dichotomum L. var. puberulum Fern. & Grisc. can be propagated through several methods, including:
Seed Propagation
Seeds of Trichostema dichotomum L. var. puberulum Fern. & Grisc. can be collected from the plant, dried and stored in a cool, dry place until the next planting season. The seeds can be sown directly into the soil in the fall or early spring. The soil should be well-draining and moist for successful germination.
Cuttings
Trichostema dichotomum L. var. puberulum Fern. & Grisc. can also be propagated through stem cuttings. Cuttings should be taken from the plant during the spring or summer and should be at least 4-6 inches long. The lower leaves should be removed, and the cutting should be planted in a container with well-draining soil. The container should be placed in a warm, humid place until the roots develop. The new plant can then be transplanted into the ground.
Division
Dividing an established Trichostema dichotomum L. var. puberulum Fern. & Grisc. plant is another propagation method. The plant can be dug up and carefully divided into smaller sections. Each section should have a well-developed root system. The divided sections can then be planted in a new location with well-draining soil and regular watering until established.
Disease Management
Trichostema dichotomum L. var. puberulum Fern. & Grisc. is generally a resistant plant, but it can still be affected by fungal or bacterial diseases.
Leaf spot disease: This disease is characterized by small, circular, grayish-white spots on the leaves. To manage this disease, it is best to remove infected leaves and avoid wetting the foliage. The use of copper fungicides may also help control the spread of the disease.
Powdery mildew: This disease is characterized by a white powdery substance on the leaves. It is caused by a fungus that thrives in warm and humid conditions. To manage this disease, it is best to keep the foliage dry and increase air circulation around the plant. The use of sulfur-based fungicides may also help control the spread of the disease.
Pest Management
Trichostema dichotomum L. var. puberulum Fern. & Grisc. is also prone to pest attacks. These pests can cause damage to the plant and compromise its overall health.
Aphids: These tiny insects can be found on the underside of leaves, sucking out the sap from the plant. To manage this pest, it is best to spray the foliage with a strong jet of water or insecticidal soap.
Spider mites: These pests can also be found on the underside of leaves and cause yellowing and browning of the foliage. To manage this pest, it is best to spray the foliage with a strong jet of water and increase humidity around the plant.
Caterpillars: These pests can cause damage to the foliage by chewing through the leaves. To manage this pest, it is best to pick them off and dispose of them. The use of bacillus thuringiensis (BT) may also help control the spread of the pest.
