Light Requirements
Leucanthemum lacustre requires full sun exposure to grow and perform best. They can tolerate some shade, but it should not be excessive as it can lead to weak growth and fewer flowers. Therefore, it is best to plant them in an open, exposed area where they can receive at least six hours of direct sunlight each day.
Temperature Requirements
Leucanthemum lacustre is a hardy perennial plant that can tolerate a wide range of temperatures. They prefer cool to moderate temperatures between 60°F and 80°F, and they can handle light frost and snow. However, they are not well adapted to hot and humid conditions, and prolonged exposure to high temperatures can stress the plant and reduce its growth and flowering.
Soil Requirements
The ideal soil type for Leucanthemum lacustre is well-draining soil that is rich in organic matter. They can grow in sandy or clay soils, but it should be well-draining to prevent root rot. The soil pH should be slightly acidic to neutral, ranging from 5.5 to 7.0. It is recommended to amend the soil with organic matter such as compost or aged manure before planting to improve soil fertility and water retention.
Cultivation Methods
The Leucanthemum lacustre plant is best grown in full sunlight. It can tolerate partial shade but may result in fewer flowers. The plant prefers well-drained soil and can thrive in most soil types, including sand, clay, or loam. It is tolerant to drought and salt, making it ideal for coastal landscapes.
Watering Needs
Regular watering is necessary during the plant's establishment phase. Once established, the plant can tolerate drought conditions, and overwatering can cause root rot. Water the plant deeply once a week, or when the top few inches of soil are dry. It is advisable to avoid waterlogging, as the plant can be prone to root rot.
Fertilization
The Leucanthemum lacustre plant is a modest feeder and needs minimal fertilization. Apply a slow-release fertilizer at the beginning of the growing season, following the manufacturer's instructions. If necessary, top-dress the plant with a balanced fertilizer midway through the growing season. Avoid using high-nitrogen fertilizers, as this can result in a weaker plant with fewer flowers.
Pruning
Prune the plant after flowering to remove spent blooms and encourage bushy growth. If you wish to reduce the overall size or shape of the plant, trim it by a third. Avoid pruning the plant too heavily, as this can weaken it and reduce the number of flowers it produces.
Propagation of Leucanthemum lacustre
Leucanthemum lacustre, commonly known as the lake oxeye daisy or the clumping daisy, is a herbaceous plant species native to Europe. This plant species can be propagated through both sexual and asexual means. The asexual propagation of the species is by division, while the sexual propagation is through seed.
Division
Propagation of Leucanthemum lacustre through division involves separating the root ball of an established plant into smaller clumps. This method is best for maintaining the characteristics of the parent plant and ensuring uniformity. The best time to divide the plant is in spring or early autumn after the flowering cycle is complete. The steps involved in dividing the plant include:
- Carefully dig up the plant and remove any excess soil on the roots.
- Identify the natural points of division, which are usually where the stems emerge from the root system.
- Using a sharp, sterilized knife, carefully separate the clumps, making sure each division contains an equal share of roots and shoots.
- Plant the divisions in their new location at the same depth as the parent plant and water thoroughly.
Seed Propagation
Propagation of Leucanthemum lacustre through seed is an easy and cost-effective method of multiplying the plant species. It is best done in spring or autumn by sowing the seed in a seed starting tray, greenhouse or any well-draining soil. The steps involved are:
- Collect mature seeds from the plant when the seed heads have turned brown and dry.
- Clean the seeds by removing any chaff, debris, or non-viable seed.
- Fill the seed tray or pot with a moist, well-draining soil mix that is made up of a combination of peat moss, perlite, and vermiculite in equal measure.
- Sow the seed evenly on the top of the soil, lightly press them down and cover them with a thin layer of soil mix.
- Water the soil lightly and evenly, cover the seed with a plastic wrap to create a greenhouse effect, and place in a warm, bright, and humid location.
- After a week, remove the plastic wrap, and place the seedlings in a bright, but cool location.
- Once the seedlings are 3-4 inches tall with several sets of leaves, transplant them into their permanent location in the garden.
Disease and Pest Management of Leucanthemum lacustre
Leucanthemum lacustre, also known as lake daisy, is a hardy perennial plant that is native to Europe and Asia. It is commonly grown as an ornamental plant for its attractive white or yellow flowers. However, like all plants, it is susceptible to diseases and pests that can affect its growth and health. Here are some common diseases and pests that might affect the plant and ways to manage them.
Diseases
One of the common diseases that affect Leucanthemum lacustre is powdery mildew. This fungal disease appears as a white powdery coating on the leaves, stems, and flowers of the plant. It can cause the plant to wilt and become stunted. To manage powdery mildew, avoid overhead watering of the plant and maintain good air circulation around it. If the disease is severe, consider using fungicides such as sulfur or neem oil.
Another disease that can affect the plant is leaf spot, which appears as brown or black spots on the leaves. It is caused by fungal infections, and in severe cases, it can cause defoliation of the plant. To manage leaf spot, remove infected leaves and practice good sanitation by avoiding overhead watering and removing fallen leaves from around the plant. Fungicides may also be used in severe cases.
Pests
Like many other plants, Leucanthemum lacustre is susceptible to aphids, which are small insects that feed on the sap of the plant. They can cause the leaves to curl and distort, and also excrete a sticky substance called honeydew, which attracts ants and can lead to the growth of sooty mold. To manage aphids, spray the plant with a strong stream of water to dislodge them, or use insecticidal soap or neem oil if the infestation is severe.
Another pest that can affect the plant is the leaf miner, which is a small insect that tunnels into the leaves of the plant and feeds on the tissue inside. This can cause the plant to become weak and stunted. To manage leaf miners, remove infected leaves and practice good sanitation by removing fallen leaves from around the plant. In severe cases, insecticides such as pyrethroids may be used.
Overall, by being aware of the common diseases and pests that can affect Leucanthemum lacustre, you can take necessary steps to prevent them and ensure the healthy growth of your plant.
