Cultivation
Bromus secalinus L. ssp. grossus (Desf. ex DC.) Domin, also known as the giant chess or the tall chess, thrives in areas with well-drained soil and plenty of sunlight. The plant is best grown in areas with a Mediterranean climate characterized by long, hot, and dry summers, and mild-to-cool winters with moderate rainfall.
To grow Bromus secalinus L. ssp. grossus, start by preparing the soil and removing any weeds. Plant the seeds in rows or patches, about 1-2 inches deep, and 6-12 inches apart. Cover the seeds with soil and tamp the soil gently to ensure good soil-to-seed contact. The best time to plant the seeds is in the early spring after the last frost.
Watering Needs
Bromus secalinus L. ssp. grossus requires moderate watering. Water the plants when the top 1-2 inches of soil is dry. Providing too much water can cause the roots to rot, which can be fatal to the plant. However, avoid letting the soil completely dry out as it can cause the leaves to wilt and become discolored.
Fertilization
For optimal growth, fertilize the plant every 4-6 weeks with a balanced fertilizer. A balanced fertilizer contains equal parts nitrogen, phosphorus, and potassium. Alternatively, you can incorporate organic matter such as compost or manure into the soil before planting. This will provide the plant with the necessary nutrients for healthy growth.
Pruning
Bromus secalinus L. ssp. grossus does not require pruning, but it can be beneficial to the plant's overall health and appearance to remove dead, damaged, or diseased leaves and stems. The best time to prune is in the late fall or early spring before new growth appears. Use sterilized pruning shears to avoid transmitting any diseases to the plant and to ensure a clean cut.
Propagation of Bromus secalinus L. ssp. grossus (Desf. ex DC.) Domin
Bromus secalinus L. ssp. grossus (Desf. ex DC.) Domin is an annual plant that belongs to the grass family. There are two main propagation methods available: seeds and division of clumps.
Propagation by Seeds
Propagation by seeds is the easiest method and is commonly used. The seeds should be sown in a well-prepared soil bed in spring or autumn. The topsoil must be fine and firm to enable proper seed-soil contact. A depth of 1-2 cm is adequate for seed placement. If sowing in rows, allow 10-15 cm between the rows. After sowing, cover the seeds with a light layer of soil and then water thoroughly.
The seeds take around 2-4 weeks to germinate, depending on the soil temperature. Keep the soil moist during the germination period. After establishment, thin the seedlings to 10-15 cm apart to ensure less competition for nutrients, sunlight and water.
Propagation by Division of Clumps
The division of clumps is a traditional method used by gardeners. It is often used when one wants to propagate the plant and at the same time renovate the lawn. Spring and autumn are the best seasons to carry out this method.
Start by digging out a clump of the plant using a garden fork or spade; ensure that the clump is not too big or too small. Remove the soil, including the roots, allowing the soil to break away from the roots smoothly.
Once the clump has been lifted, divide it into smaller sections using a sharp blade or spade. Each portion should have roots and green leaves. Ensure that the roots are not damaged during division. Replant the divided sections in another soil bed with well-prepared, fertile soil, ensuring that they are at the same depth they were previously planted, and then water thoroughly.
The divided sections should be planted with 30-45 cm spacing to ensure they have ample space for more growth, sunlight, water and nutrients. Regularly watering the plants is essential to ensure that they establish healthy roots.
Disease and Pest Management for Bromus secalinus L. ssp. grossus
Bromus secalinus L. ssp. grossus, also known as the giant brome grass, is a perennial plant that can be affected by several diseases and pests throughout its life cycle. Being aware of the common problems that can affect the plant can help prevent and manage them, ensuring a healthy harvest.
Common Diseases
The most common diseases that can affect Bromus secalinus L. ssp. grossus are stem rust, leaf rust, and smut. Stem rust is caused by the fungus Puccinia graminis, which infects the stems of the plant, causing yellow-orange pustules to form. Leaf rust, caused by the fungus Puccinia recondita, infects the leaves of the plant, causing small yellow-orange pustules. Smut is caused by the fungus Ustilago hordei and typically affects the flowers and kernels of the plant, causing them to turn black and swollen.
To manage these diseases, it's important to plant disease-resistant varieties of the plant when available. Crop rotation can also be helpful, as it prevents the build-up of fungal spores in the soil. Additionally, consider using fungicides and applying them as early as possible in the growing season when the plant is most susceptible.
Common Pests
The most common pests that can affect Bromus secalinus L. ssp. grossus are aphids, cutworms, and grasshoppers. Aphids are small, soft-bodied insects that feed on the sap of the plant, causing distorted growth and stunted plants. Cutworms are caterpillars that feed on the stems of the plant, cutting them off at the soil line. Grasshoppers are large, jumping insects that can cause significant damage to the leaves and stems of the plant.
To manage these pests, consider implementing cultural controls such as planting at the correct time and using proper planting density. Maintaining proper irrigation and fertilization can also help to minimize pest pressure. In addition, physical controls can be implemented, such as handpicking or using sticky traps. Biological controls, such as the introduction of natural predators of the pests, can also be effective.
In severe cases, chemical controls such as insecticides can be used to manage the pests. It's important to carefully read and follow label instructions when using any chemical control and to consider the potential impact on beneficial insects and the environment.
