Temperature Requirements
The optimum temperature range for the growth of Aira capillaris Host is between 15-20°C. It can withstand lower temperatures, but it may show stunted growth and reduced overall vigor. On the other hand, higher temperatures can lead to wilting and damage of the plant.
Soil Requirements
Aira capillaris Host can grow in a wide range of soil types, but it prefers well-draining soil that is moist, loose and rich in organic matter. It can tolerate soils that are slightly acidic or alkaline, but it grows best in neutral to slightly acidic soils. The ideal pH range is between 6.0-7.0. A good soil mix with added compost can encourage the growth and development of this plant.
Cultivation methods
Aira capillaris Host, non Savi, commonly referred to as hair-grass, is a grassy plant that grows well in most soil types. It can tolerate both acidic and alkaline soils, but it prefers neutral soils. You can sow the seeds of this plant in early spring or late fall, and it will germinate in a few weeks if the soil is moist.
You can cultivate Aira capillaris Host, non Savi as a ground cover in the garden or on a lawn. To achieve a desirable effect, plant them in groups of three or four rows, and leave about two inches between each plant. The plant grows up to six inches, creating a beautiful, lush carpet of green.
Watering needs
Aira capillaris Host, non Savi, needs frequent watering, especially during the hot and dry seasons. Ensure that the plant receives water evenly across the soil to prevent the roots from drying out. Avoid overwatering the plant as it can cause fungal infections that can kill it.
Water the plant twice a week or more, depending on the humidity and the soil type. If the soil around the plant feels dry, then it’s time to water it. However, if it feels moist, it is best to let it be and check the soil moisture after a day or two.
Fertilization
Aira capillaris Host, non Savi, is a low-maintenance plant that does not need frequent fertilization. However, you can fertilize it in late winter or early spring with a general-purpose granular fertilizer. Scatter the fertilizer around the plant, and water it in gently to promote absorption.
Alternatively, you can use organic fertilizer or compost on your Aira capillaris Host, non Savi. It provides the nutrients the plant needs gradually, preventing fertilizer burning. You can apply the organic fertilizer once a month, and water the plant immediately after application to encourage the absorption process.
Pruning
Aira capillaris Host, non Savi, does not need frequent pruning as it is a low-growing, compact plant. However, you can trim the plant to maintain its shape, especially if it spreads too far into the lawn. Use clean and sharp garden scissors or pruners to avoid damaging the roots or affecting the plant's growth.
Trim the plant once a year, preferably in late spring or early summer, when it's actively growing. Cut the plant to the desired height, leaving at least one inch of green growth to aid regrowth. Avoid cutting it too short or completely removing the green growth as it can weaken or kill the plant.
Propagation of Aira capillaris Host
Aira capillaris Host, non Savi, is a grass species that is commonly known as hairgrass. It is a low-growing grass that is native to Europe and it is often used as a groundcover. The plant can be propagated through various methods such as seed propagation, division, and stem cuttings.
Seed propagation
One of the easiest methods of propagating Aira capillaris is through seed propagation. The seeds need to be sown in a well-draining soil mix. The soil should be moist but not waterlogged. The seeds should be sown shallowly and pressed lightly into the soil. It is essential that the seeds are kept moist until they germinate. This can take anywhere from one to three weeks. Once the seedlings are established, they can be planted in their permanent location.
Division
Aira capillaris can also be propagated through division. This method involves dividing the plant into smaller sections and planting them in separate locations. To divide the plant, carefully dig up the entire plant and gently separate the individual clumps. Each clump should have roots and some foliage. Once the clumps are separated, they can be replanted in their permanent location. It is important to water the newly planted sections well to help them get established.
Stem cuttings
Propagation of Aira capillaris can also be done through stem cuttings. This method involves taking stem cuttings from the mother plant and rooting them in a soil mix. The cuttings should be taken from healthy stems and should be about six inches long. Remove the lower leaves from the stem and dip the cut end of the stem in rooting hormone. Plant the cutting in a well-draining soil mix and water it well. Keep the soil moist until roots develop and the new plant begins to grow.
Propagation of Aira capillaris Host, non Savi, can be done through various methods. Seed propagation, division, and stem cuttings are all effective methods for propagating this low-growing grass species. Choosing the right method depends on the individual gardener's preferences and the availability of resources.
Disease and Pest Management for Aira capillaris Host, non Savi
Aira capillaris Host, non Savi is a grass species with a reputation for being tolerant of adverse conditions. However, like any other plant, it is still vulnerable to pests and diseases. Here are some common disease and pest problems that might affect the plant, and ways to manage them:
Diseases
Fungal leaf spot - This disease is caused by various fungi and is characterized by small, round spots on leaves. Over time, the spots may grow and merge, causing the leaves to turn yellow and die. To manage this disease, avoid overhead watering and remove any infected plant debris. Also, ensure good air circulation around the plant to reduce the humidity that fungi thrive in.
Root rot - This disease is caused by overwatering or poorly-drained soil, leading to the fungal infection of the plant roots. Infected plants are susceptible to wilting and stunted growth. To manage this disease, avoid overwatering and make sure the plant is growing in well-drained soil. Additionally, pruning the affected foliage, cleaning up infected plant debris, and treating soil with fungicides will help curb the spread of root rot.
Pests
Grasshoppers - These voracious pests can cause significant damage to Aira capillaris Host, non Savi. They feed on leaves, causing the foliage to appear ragged. To manage them, use a combination of methods such as providing physical barriers such as mesh screens or netting, use sticky traps, use repellents, and treat with insecticides.
Aphids - These tiny insects suck the sap from the plant, leading to twisting or curling of leaves. Their secretions can cause fungus to grow on the plant's surface, further weakening it. To manage an aphid infestation, use insecticidal soap or neem oil, provide adequate plant nutrition, prune affected parts of the plant, and remove affected plant debris.
Proper care and maintenance practices, such as providing adequate water, sunlight, fertilizer, maintaining good soil health, and promptly addressing any signs of disease or pest damage, can significantly reduce the severity of diseases and pests.
