Briza Minor L.

Overview of Briza minor L.

Briza minor L. is a plant belonging to the Poaceae family, also known as the grass family. It is commonly called small quaking grass, lesser quaking grass, or little quaking grass. This perennial species is native to Europe, but it is now found across many parts of the world, including Asia, Africa, Australia, and North America.

General Appearance of Briza minor L.

The small quaking grass typically grows to a height of 20 to 60 cm and has a tufted, erect, and glabrous stem. The leaves are narrow, flat, and taper towards the tip, with a green-blue hue on the upper surface and a light-green or almost white lower surface. The plant blooms from May to July, producing small, spike-like panicles that hang from slender branches, earning its name quaking grass.

Uses of Briza minor L.

Although it is not commonly cultivated, Briza minor L. is used by some gardeners as an ornamental plant, usually grown for its attractive and delicate inflorescence. The plant is also edible, with the young leaves and stems added to salads, soups, or stews. Moreover, the seeds of the small quaking grass can be used for decoration, particularly in dried flower arrangements, as they create a wonderful quivering effect when moved.

Light Requirements

Briza minor L. typically prefers partially shaded to full sun areas with moderate to high light availability for optimal growth. The plant can tolerate some shade, although it may result in less dense growth and shorter inflorescences.

Temperature Requirements

The plant is primarily adapted to temperate regions and can withstand cold temperatures up to -12°C (10°F). Briza minor L. grows and thrives best in regions with cool, moist summers and mild winters with temperatures ranging between 10-22°C (50-72°F). Extreme temperatures such as heatwaves or extended frost periods can negatively impact or halt growth.

Soil Requirements

Briza minor L. prefers well-draining, fertile soils where the pH falls within the range of 6.0 to 7.5. The plant is well adapted to growing in a range of soil types, including sandy, loamy or clay soils, as long as it is well-draining. Silt or muddy soils can be problematic and may lead to root rot and stunted growth. The plant is sensitive to drought, therefore, regular watering is recommended for optimal growth and reproduction.

Cultivation

Briza minor L., also known as little quaking grass or small quaking grass, is a cool-season annual or perennial grass that is easy to grow. It prefers a sunny site with moist, well-draining soil and can tolerate partial shade. The seeds can be sown directly into the soil in the early spring or fall. If starting indoors, sow the seeds about six weeks before the last frost date and keep at a temperature of 60-70°F until germination.

Watering Needs

Regular watering is necessary to keep the soil moist, but avoid overwatering as this can cause root rot. Water the plants deeply once a week, and more often during periods of hot and dry weather. Mulching around the plants can help retain moisture, reduce weed growth and prevent soil erosion.

Fertilization

Briza minor L. does not require much fertilization. If necessary, apply a balanced fertilizer in the early spring. Avoid using high nitrogen fertilizers as this can promote excessive leaf growth and reduce seed production.

Pruning

Briza minor L. does not require pruning as it is a clumping grass that naturally sheds its dead leaves. However, if necessary, remove any dead or damaged leaves or stems in the spring before new growth begins.

Propagation of Briza minor L.

Briza minor L., also known as little quaking grass, can be propagated by seeds or division.

Propagation by Seeds

Seeds of Briza minor L. can be sown in the spring or autumn. It is recommended to stratify the seeds in the refrigerator for two weeks before sowing, as this will enhance germination rates. Before sowing, the soil should be well-draining and enriched with organic matter. Sow the seeds about 1 cm deep and water well. Germination usually occurs within 2-3 weeks. Seedlings can be transplanted into individual pots or outdoors when they reach a suitable size.

Propagation by Division

The clumps of Briza minor L. can be divided in the spring or autumn. Using a spade or garden fork, gently dig up the clump and separate it into smaller pieces. Each division should have a good amount of roots attached. Replant the divisions in well-draining soil, water well, and keep them moist until they establish. Dividing the clumps every three years will help maintain the plant's vigor.

Disease Management

Briza minor L. is relatively resistant to diseases. However, it can be affected by fungal diseases such as rust, leaf spot, and powdery mildew. To manage rust, plant resistant varieties and avoid overcrowding the plants. Also, ensure that the plants are well-spaced to promote air circulation. For leaf spot and powdery mildew, prune off the affected leaves and apply fungicide sprays as recommended by a plant pathologist.

Pest Management

Several pests can affect Briza minor L., including aphids, mealybugs, and spider mites. To control aphids, introduce natural predators such as ladybugs and lacewings or wash them away with a strong jet of water. For mealybugs, remove them by hand or use insecticidal soap. For spider mites, use an insecticide spray or introduce natural predators such as predatory mites or thrips.

Another common pest that affects Briza minor L. is slugs and Snails. To manage them create copper barrier around the plants, use slug pellets or trap them
