However, it is important to note that Cotula multifida DC. cannot tolerate extreme temperatures. The plant prefers temperatures ranging from 16-24°C (60-75°F), but it can survive temperatures as low as -5°C (23°F).
Soil Requirements
Cotula multifida DC. grows in a wide range of soil types, as long as they are well-draining. The best type of soil for growing Cotula multifida DC. is a loamy soil with a pH of 6.5-7.5. The plant does not tolerate heavy clay soil or waterlogged soil. Before planting, ensure that the soil is well-draining by adding organic matter such as compost or sand.
In summary, Cotula multifida DC. is a hardy plant that grows in a range of conditions. To achieve optimal growth and development, the plant requires full sun to partial shade, temperatures ranging from 16-24°C (60-75°F), and well-draining soil with a pH of 6.5-7.5. With the right conditions, Cotula multifida DC. can thrive in both indoor and outdoor environments.
Cultivation methods
The Cotula multifida DC. is a low-growing, evergreen plant that prefers well-draining soil and full sun exposure. It can tolerate poor soil but does not like extremely wet conditions. The best way to grow this plant is through propagation. You can propagate it through seeds or division, or cuttings from healthy plants. Make sure the new planting site has enough space for the new plant to spread.
Watering needs
The Cotula multifida DC. needs regular watering, especially during the drier months. However, it would be best to ensure that the soil dries partially before the next watering session to avoid waterlogging and root rot. Water it deeply at the base of the plant, and avoid overspraying on the leaves as it can lead to fungal diseases.
Fertilization
You can fertilize your Cotula multifida DC. plant once every three weeks during the growing season using a balanced, water-soluble fertilizer. Reduce the frequency during the winter months or the plant's dormant season. Avoid overfertilization, as it can lead to excessive growth and reduced flowering.
Pruning
The Cotula multifida DC. plant requires no pruning, but you can trim it if it outgrows its space or to retain its shape. The best time to trim it is during the spring before the new growth appears. Use clean and sharp shears to avoid infecting the plant with diseases. Trim the plant to your desired size and shape, but avoid cutting it all the way back to the woody stems.
Propagation of Cotula multifida DC.
Cotula multifida DC., commonly known as fernleaf or lacy cotula, is an easy-to-grow plant that is native to South Africa. The plant is a member of the Asteraceae family and is a perennial ground cover that typically grows up to six inches tall and spreads up to four feet wide. Propagation of Cotula multifida DC. can be done through various methods.
Propagation by Seeds
Cotula multifida DC. can be propagated by using seeds that are sown directly outside in their desired location. The ideal time to sow the seeds is in the spring season, and the location should be the one that has well-draining soil, a full sun exposure, and a moderate level of moisture. The seeds should be sown at a depth of 2mm to 5mm in rows that have been spaced 15 cm apart. Germination requires temperatures between 18 to 21°C and may take around two to three weeks. Regular watering of the area should be done during the germination period, keeping the soil moist until the plants have started growing.
Propagation by Cuttings
Propagating Cotula multifida DC. can also be done through cuttings. The steps involved in cutting propagation are as follows; firstly, select a healthy stem from an existing plant, then cut it about 5cm-10cm in length. Remove the lower leaves on the stem and dip it in a rooting hormone solution that stimulates root growth. Insert the cutting into growing medium and keep it moist at a suitable temperature of 18 to 21°C. Roots usually develop between three to six weeks. Once the roots start to develop, they should be transplanted to a larger pot or directly to the garden where they can grow.
Propagation by Division
The propagation of Cotula multifida DC. can also be done through division. It is a suitable method for older plants that have become overgrown. The ideal time for division is in the spring with an already established plant. Dig up the plant and gently separate the plant's clumps with a garden fork or hands, ensuring that each division has roots and leaves. Transplant the separated divisions to a suitable location with well-draining soil, moderate moisture level, and full sun exposure. Water the plants for the first week while the roots establish, and the plants regrow.
Overall, Cotula multifida DC. is an easy plant to propagate and maintain, making it ideal for use in border gardens, rock gardens, between stepping stones, or any place where plants with small foliage are desired.
Disease Management
Cotula multifida DC. is generally a hardy plant and has no notable diseases that affect it. However, like all plants, fungal and bacterial infections are possible. The most common issues that arise are fungal infections such as leaf spots and blights. These diseases spread by water splashing the spores from diseased to healthy plants. Overhead watering should, therefore, be avoided, or it should be done early in the day so the water has a chance to evaporate before evening.
If leaf spots or blights appear, it's best to remove the infected leaves and dispose of them to prevent the spread. Fungicides containing copper can also be used to control the disease. To prevent bacterial infections, plant spacing should be sufficient to allow air circulation through the foliage. This helps reduce the humidity levels, which are a breeding ground for bacteria. Proper pruning of the plant is also necessary.
Pest Management
Cotula multifida DC. is relatively pest-resistant. However, some common pests that might affect the plant include a variety of mites and insects such as aphids, thrips, and whiteflies. The best way to prevent these pests from infesting your plants is by keeping your garden beds clean and reducing the incidence of weeds. A clean garden prevents these pests from finding a haven.
If pests are present, identifying them is the first step in controlling them. Once identified, insecticidal soap or oil spray can be used to control aphids and other insects. Neem oil spray can also be used as a deterrent. Mites, on the other hand, can be controlled by maintaining proper humidity levels or releasing natural predators like ladybirds or lacewing insects. Using chemical pesticides should be a last resort. These chemicals can be toxic to beneficial insects, including bees and butterflies.
