The pH level of the soil should be slightly acidic to neutral, ranging from 6.0 to 7.5. It prefers soil that is moist, but not waterlogged, as excess water can damage the roots and lead to rotting. The plant can grow well in rocky areas, meadows, and pastures with well-draining soil.
Cultivation methods
Veronica serpyllifolia L. ssp. humifusa (Dickson) Syme, commonly known as thyme-leaved speedwell, is a hardy perennial herb that is easy to cultivate. It thrives in a variety of soil types, including sandy, loam, and clay soils. The plant prefers a location with full sun exposure, but it can also tolerate partial shade. The ideal planting time is in the spring, after the last frost.
Watering needs
Thyme-leaved speedwell is drought-tolerant, but it requires moderate watering during dry spells. Water the plant deeply once a week, but reduce the frequency during rainy periods. Avoid overwatering, as this can lead to root rot.
Fertilization
Thyme-leaved speedwell is not a heavy feeder, so it does not require frequent fertilization. However, adding compost or well-rotted manure to the soil before planting can improve soil fertility and promote healthy growth. In addition, a balanced fertilizer can be applied once in the early spring before new growth appears.
Pruning
Thyme-leaved speedwell does not require pruning to maintain its appearance, but it can be trimmed back after flowering to encourage bushier growth. It can also be deadheaded regularly to promote new blooms. Remove any dead or yellowing leaves throughout the growing season.
Propagation of Veronica serpyllifolia L. ssp. humifusa (Dickson) Syme
Veronica serpyllifolia L. ssp. humifusa (Dickson) Syme or Thyme-leaved Speedwell is a practical option for propagating in a garden setting. It is a low-growing evergreen perennial that produces blue flowers in the summer.
Propagation by Seed
The most common way to propagate Veronica serpyllifolia L. ssp. humifusa is by seed. Collecting the seeds can be done by harvesting entire stalks before they have fully dried out, to prevent the loss of seeds.
After collecting the seeds, it's recommended to stow them in a dry and cool area until the next growing season. Sow the seeds between March and April, allowing natural light to promote germination. Cover the seeds with a thin layer of soil and maintain a consistent level of moisture.
Propagation by Stem Cuttings
Propagation by stem cuttings is another viable option, especially for those wanting to produce exact replicas of their favorite plant. Take 5-10 cm cuttings of the plants' new growth during the spring or early summer months.
Strip the lower leaves of the cutting and dip the end of the stem in rooting hormone before planting it in potting soil. Make sure to keep the soil moist and avoid overwatering. Place the pot in indirect sunlight and wait for the roots to develop.
Disease Management
Veronica serpyllifolia L. ssp. humifusa (Dickson) Syme is a relatively disease-resistant plant. However, certain diseases can still affect it, especially in humid environments.
One of the most common diseases that affect this plant is powdery mildew, which appears as white powdery patches on the leaves and stems. This can be managed by ensuring good air circulation around the plant, avoiding overhead watering, and removing affected parts early on before the disease spreads. Fungicides can also be used in severe cases.
Another disease that can occur is leaf spot, which appears as circular brown spots on the leaves. This can be managed by avoiding overhead watering, keeping the plant healthy through proper fertilization and watering practices, and removing affected leaves early on before the disease spreads.
Pest Management
Veronica serpyllifolia L. ssp. humifusa (Dickson) Syme is also relatively pest-resistant. However, certain pests can still affect it, especially if the plant is stressed or weakened.
One of the most common pests that affect this plant is aphids, which suck the sap from the leaves and stems, causing them to distort and curl. This can be managed by introducing natural predators like ladybugs, applying insecticidal soap or neem oil, or spraying the plant with a strong stream of water.
Another pest that can occur is spider mites, which thrive in hot, dry conditions. They suck the sap from the leaves, causing them to turn yellow and fall off. This can be managed by increasing humidity around the plant, washing the leaves with a strong stream of water, or applying insecticidal soap or neem oil.
In any case, it is important to regularly inspect the plant for signs of disease or pests and to take action early on before the problem becomes severe.
