Medicinal Uses

While large speedwell is primarily valued for its ornamental qualities, it has historical uses in herbal medicine. The plant has been traditionally used for its potential medicinal properties, although its modern medicinal uses are limited.

Water

Large speedwell prefers well-drained soil and regular watering, especially during dry periods. It is essential to keep the soil consistently moist but not waterlogged, as excessive moisture can lead to root rot and other issues. When established, large speedwell demonstrates some drought tolerance, making it a great option for gardens in various climates.

Sunlight

Veronica austriaca thrives in full sun to partial shade. It requires at least 6 hours of sunlight daily to promote healthy growth and abundant flowering. In hotter regions, some afternoon shade can help protect the plant from intense heat and sunburn.

Fertilizer

When planting large speedwell, it is beneficial to incorporate organic matter or compost into the soil to provide essential nutrients and support healthy growth. Additionally, a balanced fertilizer can be applied in early spring to encourage vigorous flowering and overall plant vitality.

Soil

Large speedwell thrives in well-draining, loamy soil. It can adapt to various soil types, as long as the soil is not overly compacted or prone to waterlogging. Maintaining proper soil pH is important, with a slightly acidic to neutral range (pH 6.0-7.0) being ideal for optimal growth.

Pruning

Pruning is a crucial aspect of large speedwell care, helping to maintain a tidy appearance and promote continuous blooming. After the initial flowering period, spent flower spikes should be promptly deadheaded to encourage reblooming and prevent self-seeding. Additionally, pruning back the plant in late fall can help prepare it for the following growing season.

Propagation

Large speedwell can be propagated through division or by taking softwood cuttings. Division is best done in early spring or early fall, and the resulting divisions can be replanted to establish new plants. Softwood cuttings, taken in late spring to early summer, can be rooted to produce new plants.

Container Popularity

Large speedwell is well-suited for container gardening, providing the opportunity to enjoy its beauty on patios, decks, or other outdoor living spaces. When growing in containers, it is crucial to select a well-draining potting mix and ensure adequate moisture levels, as containers can dry out more quickly than garden beds.

Common Diseases

Disease Diagnosis

Large speedwell is generally resistant to most diseases when grown in favorable conditions. However, it can occasionally be susceptible to issues such as powdery mildew, leaf spot, or root rot, especially in poorly drained or overly moist environments. Proper cultural care, including good air circulation and avoiding overwatering, can help prevent these diseases.

Common Pests

Large speedwell is relatively resistant to pest infestations, but it can attract occasional visitors such as aphids, spider mites, or slugs. Regular monitoring of the plant and prompt action when pests are detected can help protect large speedwell from significant pest damage.
